This amplifier is for people who are very serious about music.Lightning fast transients,crisp airy treble. Very accurate in the midrange. Bass is deep,tight,pitch perfect with Visceral impact! Revelation of low detail is superb! Installation should be done by a Certified Professional. I am very satisfied with this purchase.
This amp is running my front rear Infinity Kappa 60.9CS components 12" sub. The sound quality is fantastic and this amp has sufficient power for my speakers. I would like to point out that Soundstream's website does not provide a user manual for this amp; However, the manual I received with the amp contradicts Soundstream's specs (If you look at the pictures on Soundstream's website you will see REF5.900). The printed manual shows RMS output (@14.4v) 75X4 + 275X1 @ 4ohm or 120X4 + 450X1 @2ohm which would make it a REF5.930 @ 2ohm. I am not disappointed in the actual power output. The only thing I don't like is that the RCA inputs are not color coded or labeled for L/R; The amp states Ch1/2, Ch3/4, Ch5 (I assumed that channels 1 3 are Left and 2 4 are Right). After 30 minutes the amp was cool when I touched it though I did mount it on 1/2" standoffs because it has cooling vents on the bottom. Since this is an audiophile quality amp there are numerous crossovers, boosts, and filters. I don't know if this is good or bad but it doesn't have a built-in fuse; I'm using a 100A mega fuse which is located inches from my dual batteries.
Love this amp . Everything you need in one package. I use it daily and it hasn't let me down in the past year.
