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? 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.

Wiring a 2 or 4 channel amp to your stock speaker harness without cutting the factory wiring

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?

  5. 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.

    How to hook up an amp and sub to a stock stereo.

    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?
