It's better to run an amp at 3/4 of the max RMS of subwoofers?
I have two 500wrms sub so 1000wrms total...what if i run an amp at 1100wrms?

nothing's gonna happen

Will I see a big difference if my last amp was shooting 600wrms? now i'm going to 1100 wrms, in terms of DB and clarity?

what he said


edit: didnt read the thread properly

You are better off having more power and using less of it, the amp will work less and be more efficent in the perfect world.

^ actually most amplifiers are most efficient and run cooler when they are at full voltage swing

powerhandeling depends on the subs, box, and duration... ie. you may find your subs can take 2kw for short periods... or you could end up with blown subs using 1/2 rated power on a long road trip....

yah you will see a gain of about 1.5 db if the gain is linear

Thats true but only for a class B amp (output stage). If your amp is putting out 50% of its max voltage, half the votage is across the transistors/mosfets (dissipated as heat) and the other half is going to your sub.

Thats why class D amps are so efficient. Then send out pulses at the amps max voltage, later filtered into waves with kinda a crossover network and sent to the sub.

Youll be fine running that amp. At least youll have some peace of mind knowing your subs are getting clean power, clipping causes a lot of heat. Plus your probably not running the amp at 14.4v anyway to get that rated power output, assuming its rated at 14.4v, usually is.

thankx guys I am getting the amp install as we speak , can't wait to see the difference.


it's for Two rockford fosgate P3 rated at 500wrms.
I had a 551s before, now it's gonna be a 1051s.
