I have two 12 inch subs and the rms is 300 for each, they are 4 ohms each, so to reach the 320 watts for each on the amp, should I use the amp at max?

never run your amp at max gain it causes distortion which can kill your speakers

You can use the amp in bridged mode, but my advice is to buy a better amp..

The important factor is what max are these speakers rated at for me I am running two component sets (8) speakers with 400 max on each set comfortably and as loud as anybody would want, but I got a seperate 400 watt amp to run my single comp 12 sub. If you like it loud you want the amp max to come close to the speaker max, this amp will rate around 700 max.

I have three of these and have a 1600 watt hifonics Brutus amp and it powers them fine. The rms is 300 watts so if your getting one I'd say go for a 500 watt amp. Don't go cheap on the amp though.

From what I've read, that 4 ohm sub wants 150 watts RMS. That Alpine puts out 300 watts RMS at 4 ohms. You might save some money by looking for a bit smaller amp. But, if you don't overdrive the sub, that amp will work. It is nice clean power.

I'd suggest a 1000 watt or 1600 watt alpine my amp I had blew cuz subs couldn't reach limit at 1600 watts rms so I figure since alpine knows alpine best use it!

It's gonna be better to get two having one hooked up to 400 rms is overpowering the sub having two hooked up to 185 is not overpowering it but it isn't gonna under power it so 2 is the better option

That amp would be pushing the max RMS power for 2 subs running at 2 ohms overall.... (That amp is showing 1,200 RMS watts at 2 ohms. Each SA-12 is rated for up to 600 Watts RMS.) I run Hifonics Amps in my cars and am quite pleased. Honestly, unless you want to be heard from a mile away, you don't need two of these subs.... one is PLENTY..... That being said, once upon a time 1 had 2 JL 12" W0 subs plus 2 8" Rockford Fosgate DVC subs in a Jeep Grand Cherokee.... yes, overall the 4 subs were louder, but this is damn near close to the same loudness as those 4 were....

This amp at 4 ohms is rated at 1500 watts max and 750 watts rms. Your subs are rated at 800 watts rms & 1600 max so this amp is perfect to push them with. Now how long will this amp last is anybody's guess. Remember you get what you pay for.

Make sure you have high capacity alternator, 4gauge wire or bigger, and that your subs can be wired to 1ohm. I have mines running 2 alpine type-x 12's at 1ohm fine all day long. Great amp for the price. Best money I've ever spent on an amp.

As long as you are truly running 2ohms and the amp is pushing 300w RMS than you will be pushing it just fine. Not too hard, not to little. I run my single 10W3v3-2 by a 500/1 JL slash- which is a true 500 RMS and have had it for several years with no problems. In my opinion, don't run that sub any less than a true 300 RMS!

Hello. At 4 ohms that amp provide 525 watts. That is plenty so I would just use both channels of your amp, on for each speaker. You would not want to bridge your amp with these speakers as you would then be providing 1550 watts at 4 ohms and would almost definitely blow the speakers. Also if you bridged your amp you would only have one channel. So either you would need two amps, or you would try to daisy chain these speakers and I don't believe that amp will work at 2 ohms.

Just as long as your sub and speakers watts/rms all adds up to about 300, you should be good. Bridge the sub to get more oomph. But this can have your speakers with less power. You don't want to overload your amp. IMHO, get a mono amp that will power your sub and leave this 300w amp for your other speakers. It's what I did.

75 watts RMS Recommended and it can handle up to 150 watts RMS MAX. or if you want to go by peak power 300 watts PEAK is the max.[edit](D.J.) is right and I should have mentioned that these maximum ratings (150 watt RMS and the 300 watt PEAK) are at 8 Ohms

It'll push 225w to each so yes, it will move them, but not well and if it were my setup I'd get a bigger amp. Generally the rule for amps/subs is to match within 25% of the rated power. So 25% of 400 is 100 so I'd run between 300w-500w rms. Although, this is a cheap amp and I would not recommend it. Buy quality or else end up regretting it like I did.

I don't think I would run two of that sub because it is a 4 ohm sub. That would restrict your watts from the amp to about 300 watts output. If they were 2 ohm subs it would probably be fine. I am running one kicker 12" sub ported and it is a 2 ohm sub so I am getting 500 watt output.

Yes... BUT you need to get the dual 2 ohm versions or the single 4 ohm versions. Look up series and parallel wiring if you get the dual 2 ohm versions so that you get them wired up properly. The amp is rated at 1200 RMS at 1 ohm but when you put your three subwoofer's on you're going to be aiming for 1.3 ohms. That will put out a few hundred watts less than the 1 ohm rating and that will be just right for these champions.

Maybe too much power. Difficult to get rms figures for the amp but I reckon 300w per channel works. The amp seems quite happy driving one cabinet with one channel only. You can always use the second channel for a second cab should you ever get one. BTW. Amp still going strong. No problems.
