I just recently did what BigRed did with the 8"s in the floor. There was a major improvement with output, but I think I may have to do some dampening behind the 8"s.Yea.. especially with the clutch pedal in the way. I was thinking something similar to big reds installation, but protruding door pods can also be a option. Time will tell I suppose.
Anyhow, with the amps you listed above, you can be able to have a 3 way front stage if you go with the Diamond amps.
The 4 channel can power the mids and midbass, and the tweeters can be ran off the HU. On two recent active installs, I powered the tweets off the HU and there was more than enough output
