This is my first amplifier buy off sonicelectronix.com, shipping was fast and product came in perfect condition. This this looks and feels great, feels solid and not cheap.

Notes:

-Power terminals will accept wire up to 5mm in diameter, I measured myself and that is an accurate measurement.

-Width with end caps: 11"

-Width without end caps : 9"

I'm going to rate 5 stars for now, because the only complaint I have, which is not even a big deal, but is that the gain/level/hpf/lpf/bass boost adjusters aren't flush with the side of the amp but instead are recessed about 2mm, I'll write another review of this amp after I install it and use it for a bit.
