Wiring 2 Amps to a factory deck

[williams22 10+ year member]

I am installing a speaker amp and a sub amp in my car and keep my stock head unit. I have a 2003 Mazda 6s with the Bose system. Can someone explain what I will need and how to do this? I know there is a way to get RCA outputs from the stock deck but I don't know how to wire that. And I will need two sets of RCA cables right? Any help would be great. Thanks.

its worth it to even get a cheap headunit befor you run them off the stock

This is not an option....I would need to buy a dash trim piece that costs $170 to replace the stock head unit plus the cost of a new head unit. There's not an advantage to me.

line out converter (LOC) it will connect to your speakers and give you RCA outputs, and then from there just run (2) y adapter off the LOC to get (2) runs of RCA's

I'm pretty sure I don't need a LOC with this setup, I just don't know how to hook up RCA cables....can I just splice into the outputs to the factory amp and crimp onRCA ends? I don't even know if this is sold.

Can someone explain how to take the speaker outputs from the deck and turn them into and RCA cable that I can then split to two amps? Thanks.

I've got a 6i, and this forum has been very helpful.

I've been pm'ing one of the guys who is really hardcore into modding the car and this is the LOC (line out converter) that he uses. I think the advantage is that you can turn your gains/sensitivity up to 8V.

blackbonnie just told u how use a LOC

 

[williams22 10+ year member]

I don't need to use an LOC because the wires are already low level lines of 2v. I just need adapters to put on RCA ends and I dont know where to find these.

Helpful.

Look I'm just confused. I read a post specifically talking about my factory system and it said I don't need an LOC. The guy in that post just hooked up the speaker inputs going to the factory amp to RCA cables and he was done. My problem is I cant find RCA plugs running to bare wire to hook up to.

If you just want to hook up RCA ends that you crimp on yourself I'm pretty sure Radio Shack sells those.

Ok...I'll go searching when I have time.
