I have 2010 SV with nav, rear cam, and a crappy Bose system. I am keeping the stock head unit (for obvious reasons) and replacing amps, speakers, and adding 2 10s. My question is, if I install a sound processor, shouldn't I tap in pre amp? The amp is what destroys the signal, isn't it? I have heard some say tie in after the Bose amp, at the speaker wire. Any advice would be appreciated, and a wiring diagram would be helpful too. Thanks.

 

Why put it up twice?
