I have 3 DVC 4ohm subs (HX2 10in.) and i need an amp for them..i want to stay with fosgate for the amp also, but im not sure which one i need.
My question is, how do you determine which amp will work with which sub? the subs are rated at 500wRMS and 1000wPEAK....so im assuming i need 500w on each sub, right? so does that mean i need an amp that says it will produce 1500wRMS? @ 2 ohm (subs wired in series-parallel). or can you look at the peak output?

With a torch and a big enough hammer...it WILL friggin fit!!
Since you have 3 DVC 4ohm hx2's, I would say look for an amp that has about 1700wRMS @ 2ohms, since if you wire the 3 subs in series/parallel, you are looking at a 2.67ohm final impedance. I believe there is a way to wire the 3 subs so that the final load is 2ohms, but the power to each speaker would be different, and one or two may recieve more than 500wRMS. Here is a
diagram for series/parallel wired subs. The whole point of wiring this way is for each speaker to recieve the same amount of power. If you don't mind putting a little over 400wRMS to each speaker and you want Rockford, I would suggest the Power 1500bd or 1501bd.
on the subject why not just buy three mono block amps all at about 500wrms i think its a better route to follow

ketel's method would work if the amps in total are cheaper than the one amp. and if you run a big power line-bigger than 4 gauge- and have it goin to a distrobution block with 3 outputs and one input.
Also you might want to think about upgradeing the electrical system..aka alt and battery to be able to power those correctly.
