I have 2, 250watt subs, 700watt peak, what kind of amp should I get?

the focus on class D is unnecessary.

Needing 500w rms at 4 ohms makes a standard 2 channel amp the most logical choice. Many mid-size 2 channel amps that are 125-150w rms x 2 will bridge to around 500w rms at 4 ohms.

never use peak or max ratings to match any sub woofer to a class d amplifier.you want the normal or continuous power your amplifier can supply and your sub woofers can handle.you have 2 250 watt sub woofers you must add the RMS rating of both and find a match for continuous power from a class d amplifier at a 4 ohm load.you need a class d amplifier that's making 500 RMS at a 4 ohm load.go to (www.rockford fosgate.com woofer wiring wizard) and use there chart to wire your sub woofer to the ohms load the amplifier and sub woofers can handle.a match from subs to class d amplifier is what your looking for.or as close as possible.a channeled amplifier is not the way to go when looking for a way of powering subs.have seen many channeled amplifiers that never ran as a channeled amplifier again after being abused running sub woofers it was not built to run. a class d amplifier is set up for running sub woofers only and is built for the job. if you want a cooked channeled amp in 2 yrs go with a channeled amp.some people have to pay the price to learn a lesson.im 56 and been installing this crap for 40 yrs.(www.ebay.com/car audio then( class d amplifiers.) the same amplifiers the guy posted for a much better prices,but are not the way to go.

ok. you need to know if the subs are dual voice coil or single. you want to get a mono (1 channel) amp, they are mainly made for subs. also i recommend getting a class D amp, which basically means it will put out the rms (continuous power) it says it will. So, if your two subs are 250w rms each, you want to find a class D mono amp rated around 500w rms (don't want to over power and blow your subs, this much will be a good amount)

NOTE: DON'T EVER EVEN BOTHER WITH LOOKING AT THE PEAK WATTS OF SUBS AND AMP, RMS IS ALL THAT MATTERS.

LASTLY, you want to know how to wire your subs and amp once you pick an amp. make sure your amp is capable of powering your subs @ whatever ohms STABLE. You can find out very simply how to wire your subs and amp here:

just fill in the info as asked, and it will give you diagrams of all the possibilities.

Hope I helped (:

Well you could look at something like this and the first one would be a nice match

http://www.jlaudio.com/jx1000-1d-car-audio-jx-ampl... < 500 watts @ 4 ohms

http://www.rockfordfosgate.com/products/product_de... < 225 @ 4 ohm

you need a amp that is stable at 4 ohm
