Sound quality amp

I hooked this up to my Jl vr5.25" door speakers and this amp produced exceptional sound quality. It matched the speakers very well. I love the small form factor design of this amp because it can be hidden under your passenger seat. It should be enough power for most entry to midrange speakers.
