"Small footprint, reduced heat, clean sound, Bass++"5.0 starson by TPECanuck
Pros: Amazing sound clarity and bass performance.
Best "$ per high quality watt of sound"
Automatic on/off with the head unit; no fussing around or modifications to OEM dash unit.
1 year warranty
Amp + Focal speakers, no woofer, full impact, rich sound.
Cons: The only con is that I did not try this amp before I spent big money on a Focal Solid 4 amp that turned into a nightmare. Ok, in fairness, this unit was available then.
Summary: I have no regrets about this unit and it is one of the few electronic purchases I have made where there really aren't any clear trade-offs. To me, and for my needs (not audiophile but certainly discriminating taste in sound), this is the perfect unit.
