Would this amp safely and efficiently power a 450 watt dual 4 ohm subwoofer or would I need something more powerful at 4 ohm

Yes it would run it safely and efficently, im running a alpine type r 10 with dual 4ohm voice coils wired to 2ohms on this amp, and it hits hard. mines running at 550 watts
443456
Mine came tested from alpine at 580 watts. I'm running a 300w 4 ohm dual voice coil at 2 ohms. The amp is set on 50% and it kicks. The added bass boost sets it over the top.
443457
you would put the speaker in series to drop it down to 2 ohms if you parallel it it will come out to 8 ohms check with ohm meter if you don't believe
443458
If it is dual 4 ohm wire it in parallel and it will be a 2 ohm load on the amp which is 500 rms which should match it perfect
443459
yes. since it is a dual 4 ohm sub, it should be wired down to a 2 ohm load. and the amp does 500 on a 2 ohm load. it will be best to set gains with a multimeter.

It'll certainly work and work nicely. If you're looking for a lot of power you may want to consider a unit with more wattage. If you are happy with moderate volume you're certain to enjoy this amp.

Or 93watts x4 at 2 ohm is what my alpine sheet says i definately suggest alpine amps ive had a 500 watt mono for 4 years now still goin strong

yes, you can, but keep in mind that the nominal power for the amp is 300 W, you won't be able to extract more energy from the amp. (300 W is still a lot for a subwoofer!). You might want to connect the two subwoofers in Parallel and that will reduce the total ohms from 8 to 4. You can also connect them in series, but that is going to increase the resistance (to 16 ohms) and that will mean that the transfer of energy won't be optimal (i.e. they will sound with low volume)

Yes it would be a lot of power indeed. But take note. It might be to much. Check to see how much your subwoofer peaks to. The boss amp is 5000 so u would need both subs to be 2500 max peak. Hope this helped. If ur confused ask me again.

As long as u dont rasie the volume too much it should be fine but i would get a more powerful amp

I am using this amp for 2 4000 watt subs. Might be a little strong for 1 2700 watt. I also have 2 1300 watt subs powered by a 1000 D class amp that sound great. If you're only using the one sub, I recommend a 2000-3000 watt amp. Take a look at the AC3000.1D. Should be plenty of power. AND, cheaper. Hope you're his helped.

The Sound Storm 4000 watt that I looked up is 1 ohm stable, so yes it would work. To get the most power, you would want to hook the sub up in the 1 ohm configuration, not the 4. 4000 watts is huge overhead, so just be careful not to blow the sub by turning the volume up too high.

Thank you for asking. The powered outputs on this are stable down to 4 ohms. As long as the impedance on your speakers is high enough the amp will be ok. If the speakers are rated to the right power they will be safe as well. Have a great day!

the amp is 2 ohm stable so you can use a single dual 4 ohm voice coil sub wired in parallel and see the rated output of 350 Watts but you must be aware that at 2 ohms more potential for stuff to go wrong. it is theoretically more stable at 4 ohms so its really up to you, how loud do you want it.

You need to dual voice coil 4 ohm with that amp. You can only drive as low as 2 ohms stable with that sub set if you try for 1 ohm you will end up with a 1/2 ohm load. And the amp is not rated for that

not too sure i have it running at 1ohm and it's great, the amp pushed my Diamond 12" 400watt sub great, clean sound too, getting the Alpine SWR-12D2 12 next week I'll let you know well it pushes that. I have my doubts but only time will tell, I can tell you that's it's not 3000 watts tho, but from experience it's enough for a single 12" 400 watt sub.

Jonathan, here is some information that might help320W @ 8 Ohms480W @ 4 Ohms700W or 480W Amp Only:¼" speaker outputjacks. Impedances Lower than 4 Ohms should not beused. Higher impedances such as 8 Ohms, 16 Ohms,or No Load are acceptable. One 4 Ohm, one 8 Ohm,or two 8 Ohm cabinets are okay. One 4 Ohm and one8 Ohm together is not recommended. The internalspeakers equal an 8 Ohm load. No damage willresult from operating the amplifier with the speakersdisconnected.

Depends on your setup - if you are going to use it just for sub then 4 ohm, if you are going to use it multi channel, then 2 ohm. Caution, this amp shuts down easily when "overloaded" or too much current is drawn.

This amp is good for any subs, the factor is to get the Ohms as low as possible so you can get advantage of the full power. If you can get 1 ohm you will get the full 1100 Watts. What are your subs specs?

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

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.
