Factory head unit in 2007 Camry. I have a new set of Kicker speakers to replace my rear speakers. I have a 12" Fosgate powered sub, and a 4 channel Fosgate amp that I'm going to bridge and power the new Kickers. I have a high level to low level (RCA) converter (don't know for sure if I need it). The powered sub and the amp will take high level or low level inputs. I currently have a 8gauge power wire coming from the battery to the trunk but wonder if I need to up it to 6 gauge to a dist block, then 8 gauge to the sub and amp. I don't know if I have to put signal to both the front AND rear inputs of the four channel amp if I'm going to bridge it. Please, based on all of this info, how should I wire all this up?
Thanks so much!

I would recommend downloading the manuals for your gear. They should have most of the info. you would need and it will be a long post to explain how to install all of this. You may or may not need the LOC depending on if your amp has seperate speaker wire inputs or just RCA's.

Usually you only need to supply signal to the amp channels that you are powering a speaker with. It sounds like you may want to go to 4 gauge or larger if you have two amps running off one power wire. I think most people replace the front speakers before the rears... Also what are the models of all your gear?
