Uh, what?
Amps don't have SQ? I guess Sinfoni should close it's doors then. It's all been a waste.
Let's face it, Hifonics *****. Sure, it sounds fine when you have only run other Hifonic amps, Alpine, Pyramid, or crap alike.
People are better off investing in a quality amp. It may cost an extra $150, but atleast it does rated power and has atleast decent SQ. Not to mention, it might actually last you more than a a year or two unlike most of the budget amps.
The reason amps like this exist is to be cheap for people who don't want to spend money. With cheap, means built cheap, means crap. Simple logic.
Hifonics doesn't have some sort of secret to mass producing inexpensive amps that put out power and sound good while doing it. The secret is, silly consumers, misinformed consumers, or just people who don't care.
At the very least, and this is the very least, get a JL.
