Single channel amp question

[chevynut402]

I've got an Alpine V12 single channel amp (300 w). I'm going to install 2 10" Fosgates and was told i could split the ohms on the V12 and double the power to get 600 W. I'm trying to save space and get away with using a single amp setup. Can anybody tell me if this will work and how to do it? Any info would be great!

running 2 subs from 1 single channel amp, it's do-able, not ideal. i don't understand how it would give you double wattage though... if anything (if it's a 4 ohm amp) and you split it into 2 subs, each sub would get a maximum of 2 ohms, and you'll never get peak performance out of your subs, and you may over power the amp if you turn it up too loud for too long. 300 watts is max because that's all the amp will give, and my 12 inch sub has a 300 watt rms so i don't think that's a good setup for 2 10's.

i may be wrong and you may disagree with some stuff, but i'm no expert, just my 2 cents

If the amp is 4 ohm mono stable you will be fine if your subs are 8 ohm. If it is 2 ohm stable than you will need to 4 ohms subs to get the power you want

yea like he said u need to go with ohms for power my amp is 1100 watts a 1 ohm and im runnin it at 2 ohm which is 600 watts

Yea, you can bridge it to 600, but that is puttiing a lot of strain on the amp. And depending on what the peak is at each of the subs, you can do just as much damage to them with not enough power, as you could with too much power. If you asked me i would get a bit bigger amp. Makes it worth it, and the power will sound more solid, not like the ragged 'wanna'be' power, as i call it.... when you listen to alot of car audio setups, you'll understand what im talking about... hah. But anyway, thats my 2cents.

I've run the old V12 amps down to 1.5 ohms bridged and they have been fine. Make soure it gets good cooling! If it goes into protection mode, then the poor amp just cant take the pressure Which model amp is it? Saying its mono sounds like the new class-D sub amps, which are 2 ohm stable and put out approx double their 4 ohm rating.

I think you should be fine running two 10"s off that amp. I did have two subs hooked up to a 200W amp and they worked fine. If your subs are really power hungry though, it may have trouble keeping up with them. What model subs do you have?
I would hook it up and try it. Just make sure you don't have any distortion when you play them.

If the sub is 2ohm stable, you should be able to run both subs in a parallel circuit. Meaning both + terminals of the subs to the + terminal of the amp. And same with the - terminals. If it is not 2 ohm stable and you are dead set on running both subs off this amp, you can wire the subs in series. This means running a wire from the + of the amp to the + on one of the subs. Then from the - of that same sub to the + of the other sub. Then the - of the second sub to the - of the amp. This is all assuming that the subs are rated at 4 ohms.
