Comments about PIONEER GMD7500M MONO AMPLIFIER SUPER SMALL:

I have a 2008 Jeep Wrangler and the amp fits perfectly in the small trunk located behind the rear seat. Though not flush on the floor because the sides of the trunk are tapered, the amp still has plenty of breathing room both below and above it...and it is 100% HIDDEN! I have the gain on my RCA line out converters set to about 90%(because my head unit has no RCA jacks) and the gain set on the amp to about 90%, LP (low pass) enabled, Bass boost set to 6 and the bass is Crisp and sounds excellent. Though It is not going to rattle windows of passing cars, it will make your music sound excellent...even with the top of, and all for about 120 bucks!
