Well, after hacking into my custom made, thick plexiglass stereo plate, I put the EQ where the XM Radio used to be. I don't know where I will put it, that is I use it at all, since my headunit is XM ready. I just need that IP-Bus cable to link my CD changer to the XM reciever. I thought that I would lose my Crossover when I put in the EQ (it had a seperate subwoofer output) but it turns out that Crossover worked without using the seperate output and still dropped the bass! Tommorrow, I will put in the Infinity Kappas into the doors and rewire the enitre speaker system with Monster Cable S16-2XLN. It has 2 16 gauge wires shielded into one cable. I will run these to my front and rear speakers. I know you guys may use better wires, so which speaker wires do you guys prefer?
