So I'm looking to put some bass in (who isn't that's on this board).

In the front, I put 2 eclipse components (built-in crossover) and put the tweets in the sail panel. Sounds good

Since I'm keeping the stock system, because I like the features, especially the sync, I'm going to put an AudioControl LC6 pre-amp in (I had one in my RX8 and it cleaned up the signal, nicely).

Sub - supercrew single enclosure (10 inch model) - it's tough to find a 12 inch that would fit, depth-wise http://www.supercrewsound.com/commer...d=375&catId=58

Amplifier - This is where I really need some advice - would like a 5 -channel only because I think it would be cheaper and easier to install than 2 amps whether it's a 4 channel plus a mono or a 2 channel plus a mono.
I used a 5-channel Eclipse in my last car that was decent, but I'm open to suggestions on any part of this.

Thanks
