Interesting.

I wonder what actually comes out of the thing as far as signal quality. I've yet to even see one in person, So I have no clue about them.

The only other car amplifiers I've owned personally other then A/D/S is Zapco and this Infinity amp someone gave me. The infinity i've yet to open and have barely used. The Zapco I thought was built like garbage. Someone burnt it up and i repaired 90% of it. Got bored of it and gave it to another friend that finished

However none of that has anything to do with the Hifonics amps, So i'll have to take your guys word for now
