Thread: Wiring an amp in a car with factory deck.

Yo
u can use high level inputs. Which means you wire each speaker channel ie the positive and negative of each of his speakers in the amp. This is the less desirable way but will work for your application. As for a remote turn on you can run a line from the acc position on the ignition. So whenever the car is on the radio's amp is on. Good luck.

yes that would work or you could run a loc (line output converter) takes the high level and converts it to a low level out (rca out) a good converter will run around $20 this will let you tie into the front or rear left and right channels to get a rca out

But by using a speaker level to line level reducer (whether in the amp or external) will seriously (ie you will hear the difference ) degrade the sound. Far better to get a new head unit with line out, and spend a little less on the other.

I guess what you mean is that he intends to use the stocker speakers hooked up to the head unit. Then he wants to also have his new sub hooked up to a new amp and somehow connected to the head unit.

Actually I don't know how to do this. I suppose you could clip the rear speakers and run the rear outs into your amplifier... but then you have no rears. I'm not sure if you could run the rear speakers and a LOC in parrallel, but something about that idea makes me think it won't work too well.

Anyone else???
