I bought this amp because I needed to push 2 t2 12's and rockford 2500 amp is to expensive for me. This amp is great! Even with the amp gain all the way down the bass still hits. I have a Hifonics Brutus 2000 watt amp that doesn't put out as much power as this amp. I have an 170 amp alternator and zero gauge wire everywhere. Also I'm using 4 gauge wire to the speakers. This is a great amp at a great price. Most people just don't supply enough power to there amplifier and think the amp is the problem. Do your homework before trying to use an amplifier this powerful.

Love this. If you want the best bang for your buck this is the way to go.

Amplifiers follow the same laws of electricity that apply to everything else. AMPS x VOLTS = WATTS.

For amplifiers the formula for every manufacturer is...


I love how someone can say an amp is under or over-rated and GUESS what it is capable of. 99% of all car audio systems are severly underpowered. The amp NEEDS AMPS of current. A 2500w RMS amp needs OVER 200 amps of current to produce that much power.

When someone says a smaller amp is louder it is usually because they are deficient in current and the smaller amp needs less and if more efficient in turning the available current into watts. NO STOCK ALTERNATOR CAN PRODUCE OVER 200 AMPS OF CURRENT AT IDLE.

If you have a stock alternator, you are just pretending to have big power....period. Power cells help but the power still ultimately comes from the alternator and once the power cells are drained they cannot refill fast enough to keep up on a stock alternator.

Soundstream amps are awesome! Anyone who says otherwise is not qualified to give a relevant opinion.
