If your only doing the 2 subs and no other speakers. a decent 4 channel will do it easy, try and find a high wattage one.

depends on the RMS value of the subs. if they are about 350W RMS u might want an amp that can put out at least the same amount of power...or else u won't get the full potential. either 2 channel or 4 channel.

something like this

ahh no id be running these of a single mono block...not a multi-channel amp....it'd wanna be a damn good multi channel.

Run the subs in parrallel.

More info is needed tho.....the 1200w value is this continual power output (an RMS value) or just watts (most likely being the peak power value) meaning these subs will be round 500-600w RMS if there a decent sub....not too many 2/4/5 channel amps are gonna be able to power them to anywhere near there potential.

Let us know the sub brand and model....then we can provide a more concrete answer...on whtas gonna be the best value for money/power and how to wire it up.

if he ran them in parallel would that mean that its running at 1Ohm?

Not necessarily - the impedance (ohms) value for his woofers havent been provided yet :) why I asked fo his make n sub model :P so I coul look up specs....same with the specs of his amp so I can see what its capable of handling stable.

What is sorry dude i take it by "They" u mean the subs ? I can find any info on google anywhere for that model ?

Can u tell me whether each individual sub is a Single or Dual Voice coil sub....and it should have an ohms value....normally 2 or 4.

Their a 12" so was 1200w peak ? or RMS.... id double check that part number.

ok which is a good idea since there severly under powered at the moment...will be like a whole new sub system when ya get that amp in there :)

Clarion subs...is that 600w RMS or peak ? and rampage amp is that also 1200w RMS or peak value ?

The 2 channel - did u have them wired in parrallel and then bridged over both channels or...individually wired to a channel...and was the 400w rating also RMS rating at 12 or 14.4V at 2 or 4ohms....were the subs single/dual 2 or 4 ohm coils ...

Sorry for all te questions...but gives a soo much better picture to comment on ..

clarion sbus are 600 peak power each cant say much more then that as i am not sure on the right details rampage amp is 1200 watt peak and 400 watt amp individually wired to a channel 4ohms i think the subs are duel 4 ohm dont hold me to that as they were bought as a kit form a local clarion dealer if you need more details i will try to find out for you
