Hook up radio to amp
And if you ever did want to change the stereo, keep a look out for Alpine and iDatalink. So in the future there may be some nice options. Does tieing an LOC in parallel to the speaker circuit effect the circuit impedance? I think maybe you just mean running along side with rear speakers operating. So you can and are supposed to have your LOC installed along side your rear speakers. I hope that makes sense! Next how do i connect the wires in any case?? Do i have to keep the harness plugged into the head unit or do i have to keep it unplugged as i read somewhere you cannot power the speakers from both factory hu and amp simultaneously..
And while feeding the amp output back to speakers n subs we connect speaker wires to each speaker leads, so whats the difference between amp input signal n amp output signal, its confusing me as for eg. You can take the speaker leads off the back of the stock stereo and route them directly to your amp. The LOC is your input signal. That is feeding the actual audio signal to the amp.
The amplifier amplifies that audio signal and feeds it the speaker output. What if I were to tap into the factory speaker wires without the converter by cutting and splicing a rca cord? I think he only does this in cars that have a stock amp and have a direct low noise pre-amp level audio signal. I have an 07 maxima with a Bose amplifier. Should I tap into wires that input into the bose amp or the output wires and which colors. Hey Chris, sorry for the late reply, was busy trying to survive the holiday season at our shop. OnDemand lists black as negative and white as positive on the stock subs.
Other wise, probably behind the radio. Sounds great only one problem when car goes on or off i get an annoying distortion sound on subwoofer. Try switching the source for your remote turn on lead to a different accessory power source. What would work best? When in doubt, I would go straight to the stock sub. Where is the best place to hook up a line output converter when adding an amp for a sub? I may have missed it somewhere.
Hey Keith, you can grab that signal right at the stock Bose subwoofer. Like a positive one side of sub and negative on other side of factory sub? The stock amp really is not powerful enough nor designed to run the impedance of your MTX. So definitely get the LOC and a separate amp to power your MTX — you could also get an amp that has the LOC built into it too, but either way definitely just grab your signal from the stock sub, but use that signal to feed a dedicated amp to power your MTX. I have a ram with premium alpine system.
I want to add amps and a sub. The car is canbus equipped. How do I get a clean signal for amps. Anything I add must be tied in post factory amp. I need to clean the heavily processed signals. I will tune via aftermarket amps. Not interested in complicated dsp…. Hi Fred, I feel your pain.

You might want to would wait to see what JL comes up with, but it may be another 9 months or so before they release anything. They talked about this very problem at CES recently and they are in the process of designing a new product which tackles this exact issue. You can read more about the new JL Audio processor here , scroll towards the bottom of the post.
With this processor you also have the option of using a digital aux in so for a dedicated super high fidelity source, you can use an iPod running through a high quality digital to analog convertor straight into the processor. With Audison I had many defective units and it would take months, even over a year in one occasion, to have them repaired or exchanged one of the reasons we stopped carrying them. Sometimes you really only need to use two audio signals. So whichever route you decide to go, make sure you go to an experienced installer who knows what a frequency sweep is, a scope is, and what an RTA is and make sure he knows how to use them because you really need all three to set up a processor correctly in a vehicle like this.
Then when the Fix and the Twk comes out from JL you can clean it up even more. Those will be designed to do the tuning and tweaking themselves, making it a much simpler install. Hey I have a ram pickup with factory alpin system and touch screen deck. Has factory sub under back seat.. Had 4 wires going to that one sub.. Hi annie i have a question if i am connecting a line out converter on a factory rafio but there are no speakers installed the wires are there and i know which ones are going to each speaker how would i find out polarity on the wires.
Hi there, I just bought a cadillac CTS and I wanted to know if its possible to hook up a sub and amp to the stock stereo,if I can how do I do it?
How to hook up an amp and sub to a stock stereo.
Of course you can! I would add one clarification to your speaker polarity testing. Thanks for taking the time to post it! For readers that need more details on polarity testing you can check out this video post or this post on wiring up a head unit when the wires have been cut. Hi i just bought a Lincoln mkz. I hooked up a line output converter and when i shut my car off the amp begins to work and apply bass.
Im not sure why this is happening i read the directions,followed step by step. Everything works fine when i turn my radio on and off the amp goes off and on…. I got 2 10 inch kicker competition,and a watt power bass amp,stock radio….? Did you run the remote to an accessory or ignition wire in the vehicle so the amp goes on and off with the key? Sounds like maybe you used the signal sensing feature of your line output convertor, they can do funky things like that.
Try to find a true accessory or ignition wire to get the timing right. Hello, I just recently purchased a 04 Audi 2. I have a Infinity reference a mono-amp and 2x Infinity Reference w Inch that I used in my previous car and I have all the wiring as well looking to upgrade in the future but its what I have for now: Im thinking this will be a fairly easy task since I have everything except the LOC. What im wondering is how would I wire the input to the LOC so that I can power both of my subwoofers. The Infinity subs would be wired to your amp just like any other setup. Your only wiring options are running each subs voice coils series, then parallel the subs for a final 4 ohm load or wire the voice coils parallel, then parallel the subs for a final 1 ohm load.
That amp is not rated as 1 ohm stable, which means you were probably running the amp at 4 ohms in your last set up. At 4 ohms it only puts out watts RMS. Your subs are rated at watts RMS each. Do I need to pull the rear speaker wires from the deck and wire them into the LOC? There is also no remote wire in the harness, how does my am know when to turn on?
You may want to get your signal from the speaker wires before or after the stock amp which is located underneath the rear deck in the trunk. I have installed an amp and speakers to my factory stereo, the problem I am having now is that every time I shut off my car and turn it back on there is no signal to the back speakers. Hi Heather, I think I know what it might be, but to really answer this I would need to know a bit more. A line output convertor? Or did you cut and splice RCA cables into the stock speaker wire? Hi Brandyn, Probably running too low an impedance to the amp, this is the most common issue I see.
If your subs are dual 4 ohm voice coil, and you wired them in parallel positive to positive, negative to negative that reduces the final impedance to 2 ohms. Check out this post for more details. Theres no stock sub or anything like that its the low end model jeep. Its got 2 RCA out-put side i dont know which one to use and about 16 diffrent places to put the wires into i thought i only needed 4 slots.. What are you having trouble with exactly? Running the power wire? Where to get your signal from? How to get accessory?
I tapped into the rear speakers before the aftermarket bose amplifier because ive heard tapping into the lines after the amp will really destroy the quality of sound. What can I do to eliminate the high frequencies coming out of the subs. I have a Razor amp and 2 Zstat Razor 12s. Is there a stock subwoofer??? Look for the stock amp under the center console and look for the gray 8 pin plug, pins 7 and 3; 6 and 2.
It may be different in your truck, so always use a multimeter and battery speaker popper tester to confirm wires are correct. Also, on your aftermarket amp, make sure the low pass filter is on. Have you considered maybe the quality of the product is not up to par? Or have you used this product in other applications? They have a few applications for GM trucks shown here and they kick ass. Whenever you build an enclosure while taking into account the cabin acoustics, cabin size, subwoofer parameters, you can really build an awesome sounding enclosure.
All of those things effect the sound quality and output you will achieve. If you wanted to build your own box, we like Bass Box Pro software. How do I do this? The remote turn on could be a white wire in the stock radio harness listed in directechs software for and up. You would just need to hook that up to the remote turn on lead from your aftermarket head unit blue with white stripe.
Therefore when you adjust the bass going to your regular interior speakers, you are also adjusting the signal going to the amp. This boost in signal to the amp can result in a modest increase in bass going through your subs, but it can also put more stress on your stock speakers. With the factory premium system, the stock amp is already filtering out the bass to the stock speakers.
Most likely this is because the signal for the sub is coming from the stock sub, not the interior speakers. Most factory stereos including many premium models do not have a separate subwoofer control adjustment. So whenever I sell an amp and sub to be installed with a stock system I always sell a bass knob. A bass knob is basically a control knob that is daisy chained between the RCA connections at the amp and your high to lo level convertor. Check out this one from a BMW 3 series we recently did. Should I be able to control the bass through the bass adjustment on the factory radio?
I had this same system installed on a gmc sierra and was able to control the bass through the factory radio bass controls but nor sure why it doesnt control it on the jeep? Any suggestions would be greatly appreciated? Hello I have a question for you Annie? I just purchased an audiocontrol eqs to start my system upgrade in my chrysler with a stock head unit. My car has 6x9s in the front and the back.
My question is should run the line level in from the front speakers or the back speakers as they are the same size speakers. To check the frequency response and make sure they are playing full range and not crossed over, you can play a frequency sweep through the front speakers, then the rear and measure the response. I like this app. If so, you can:. But you can tune the Front and Rear channels separately on the amp to get a balanced sound that is appealing to you. Have a 08 ford shelby gt Sorry, saw this comment after I responded to the other one. So definitely the upgrades for wiring I mentioned earlier.
You will need a line output converter as mentioned in this article and definitely an adjustable one like the Stinger one that is shown. Sometimes you need to go before the amp, sometimes after. Every car is different, but I would try it at the factory sub first, see how it sounds and then go from there. Hi Cammy, you really should get signal from both rear speakers as your factory stereo is putting out a stereo signal to the rear speakers and the amp wants to see stereo mixed into mono.
You can grab those wires either at the speakers themselves or behind the radio. Just make sure to test for positive and negative so nothing is out of phase. Unless you can get a full range signal behind the head unit you should get your signal at the stock sub. You still need to run a remote turn on lead to the amp from an ignition power source unless you bought a signal sensing LOC with remote turn on lead. But my question is, i just bought an infinity reference a amp and want to hook it up but not sure what kind of subwoofer i will go good with it?
The other possibility here is your phase is incorrect, are you sure you got positive and negative correct? Stock wiring is never color coated to be anything like aftermarket wiring.
For example, positive in most Jeep Grand Chrerokee tweeters is usually black, and negative is green. If you have one or both of the speakers out of phase compared to all the other speakers in the car, it will sound pretty bad. One way to check this is try fading just to those speakers, than balance it left and right. The larger surface area will give you a little more kick. Very important tip here, if you are adding the amp and sub to the stock deck, you must get your signal using that hi to lo level converter at the stock subs.
This is the type of information that should be shared around the web. Shame on the search engines for not positioning this post higher! I read some of your blogs but want to get more specific with my car. It has a Harmon Carmen premium system. Is it possible to just hook up a LOC to the rear factory sub and then just run the amp from there? I was also wanted to know if it would be beneficial to put in a digital bass reconstruction box in line with this?
Thank you for your time and consideration to replying to this question. Hi David, Yeah, definitely tap your audio signal off any stock subs in the vehicle. Having a bass knob is nice even if you have an aftermarket stereo.

When connecting a line out connector to a factory head unit, it is advisable to use both sets of speaker wires to maintain the left and right stereo effect from modern music. Always remember to shut off the amp if you do so manually Soldering 12v power and ground connectors to the wires will reduce circuit resistance and make your power cleaner, giving you better sound. Make sure that you use cables with the correct resistance or impedance for your setup.
