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

For amplifiers the formula for every manufacturer is...

14.4 VOLTS x AMPS x EFFICIENCY % = RMS WATTS

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.

I dont re-call soundstream making any bad amps. Considering their old amps which were under-rated and thats what i loved about it. pretty much getting it at this price is awsome and worth the steal on it. I agree with Sam 100% less than 1-ohm is great which means you dont have to worry about non-sense. Add more power and putting this amp on a atkins power diet is a waste of your money.

 
4 Star Rating Jesse From Maine

This amp is pretty stout and you can run it at .5 daily with no issues. The only problem with it is that the amp is a bit over rated (it does closer to 2200-2300w) and it's not very efficient. I did a direct swap between this and an audioque 2200 and the AQ was a little louder and seemed to hit the lows with more authority (the subsonic filter for my 2500 wasn't set incorrectly, but because of the efficiency, the lows are louder on the 2200).

Overall the amp isn't bad at all especially if you need something inexpensive that you can run below 1 ohm. But for a daily amp @ 1 ohm I would go with something different. AQ2200, BC2000, SAZ-1500/SAZ-2000, etc.
