All the ideas are great and some of the installs are truly AWESOME. I didn't want to spend a fortune or a lot of time on my install so I simply bought a nice Bazooka subwoofer with amp installed, Put a pair of 6 1/2" pioneers in pre made kick panels, another pair of 6 1/2 pioneers in the rear deck lid, and made a simple box under the dash for the head unit. Sounds great and only took a weekend to complete.
