I have a 2012 jeep compass limited with the premium sound system (9-speaker boston acoustics sytem with factory amp & 8" sub). I am installing an aftermarket subwoofer and amplifier but before I begin I have some questions. I was reading on another thread that in order to install the amp I will need a line out converter because my amp doesn't have high level inputs, but on that thread the guy said if the jeep has a factory amplifier (which mine does) that I would need to tap into rear speaker outputs at the amp and not at the head unit....the problem is I can find a wiring diagram anywhere for the amp so I don't know which wires are the rear rights + & - and rear left + and -
also im not sure if that information is accurate, do I have to tap into the wires at the amp outputs or can I do it behind the factory head unit? and if so can someone tell me which wires and the rear speakers? thank you!!!
Have you already bought the amp ? Nowadays the amps come with high level input, so you can check other options as well. If you buy a high to low converter, and if that makes it easier for tapping wires- I would say do that.
I have installed kicker hideaway subwoofer and was tapping the full range signals as high level input. For some reason, the kicker never liked that input and always distorts the bass no matter how I set the gain. With increasing volume the amp will just cut off ( gain minimum position on the amp). So I had to use the high to low converter and that solved the problem. Again, this could be my kicker amp and not necessarily the be the scenario with every amp.
I tapped into the wires from the headunit but if you can find some location near to the factory amp, would be cleaner
