I installed Focal 165KP component speakers in the doors using the stock Bose amp. The sound of the new speakers is still bad, barely hear the tweeters. I'm blaming the crappy sound on the amp so I’m going to replace it with an ARC Audio 4150-CXLR.

My question is: Does any sell a wiring harness to connect the ARC amp to the stock wiring harness?

As you can tell I don't know much about car audio, just like quality sound.

 

I just did a full system with the OEM head unit. Focal 165K2 in front, JL 12" freeair, and an ADS P650.2 amp. I dropped the Bose amp, and it was an easy install, and it sounds amazing! I'll have pics later this week.

 

What do you mean you "dropped the Bose amp"? How did you deal with the balanced line outputs from the head unit, or do you mean that you just took the speaker outputs from the Bose amp to feed your new amp(s) like I did.

Where did you put the jl "12" sub. Since it is free air is it on the rear deck?
