So what can I say....This amp is powering my MB Quart QS216 Components. (Alpine CDA 117 deck with the PXE100 processor).
It does a great job. The SQ is great. I had really good SQ using my Kenwood amp; but this takes it to a whole new level...... Soundtage keeps getting better and better....... WOW.
The amp gets warm, but I am cranking it up often. Still has not hit protect mode yet.....
(And yes; I have a solid 4G ground).
The bass EQ and crossovers are nice features; that I do not need. (Not complaining; they seem designed to provide tight, detailed bass!)
But; If I ever decide to do subs with this amp; this will prove useful.....
I got mine on Ebay for about $40 less......
Positives:
POWERFUL.
ACCURATE.
GREAT SOUNDSTAGE.
HEAVY.
Negatives:
Big. (It is bigger than many 4 channel amps!)
No other complaints......
Buy one. Soundstream IS BACK!
Soundstream Reference Lives!
