What size amp do you reconmend for two 12" 750watt subwoofers?

Question

*Impedance: 4ohm
*Max power: 750watts
*RMS power: 150watts
*Voice coil diameter: 2"
*Magnet: 40oz
*Frequency response: 20-100Hz

Answer 1

A 300 watt RMS @ 2 ohm amp would be fine with the subs wired like so http://i81.photobucket.com/albums/j230/sparky3489/PARALLEL.jpg

Be sure the amp is CEA-2006 compliant.

RMS (root mean square) watts is a more accurate means of measuring power as opposed to max power. The reason is that an amp rarely ever reaches max, and when it does it's only for about 1/10 of a second. RMS is the nominal (average) watts an amp can push or what a sub can handle.

When subs are wired together, the watts RMS of both subs gets added together as well as the impedance (ohms) changes as well. Two 4 ohm subs wired as in the link above provides a 2 ohm load to the amp. So an amp that matches the total watts RMSa nd the new load is ideal. This is why the 300 watts RMS 2 2 ohms.

Answer 2

I've been an installer as my hobbie and for employment for fifteen years now. Brand name means alot in the car audio industry. A more expensive sub can handle the power that it states in its specs, a cheaper sub can not. The same goes for amps, a cheap amp might say that it puts out 1000 watts, but trust me it is more like 400 watts. How they get away with these misleading specs I still haven't figured that out. It also matters what type of enclosure the subs are using. A sub in a sealed enclosure can handle more power than a sub in a ported enclosure. Ported enclosures are louder than sealed, but don't handle as much power. A sealer enclosure handles more power, hits harder and sounds cleaner. So do you want to be loudest on the block or hit hard and clean??? The vehicle makes a big difference as well. SUVs are great for subs and don't take a huge amp to really pound. If you are putting the twelves in a trunk with the back seat up, you will want a bigger amp (and some Dynamat). For your subs based on the info you provided, I would choose an amp that is 2 ohm stable(wire subs in parallel) when briged (most amps are), and that puts out 500 to 800 watts total power. Hope this helps.

Answer 3

Well I would go to crutchfield and find one that has the right
RMS watts,

That is a low RMS for such a high max.

Kicker ZX350.2
2-channel car amplifier
110 watts RMS x 2

Would make those sub's hit great, You don't want you amp pushing more than your RMS

Answer 4

300 watt rms
600 max

and taht is way to high to have a rms is 150 so the guy lied to u the max i probuly only 300 i bet u hook up a 1500 watt amp it blow as soon as u hook it up

Answer 5

500 Watt if you want good base or maybe even a 500x2, just dont push it to the max.

Answer 6

all i know is over power them and not under power them or you wil damage the drivers.soz not much help but somting to start with.
