Need Amp to match 2 RF 12" P3s

Well, the system I have now (2 12" MTX Jackhammers at 250w RMS apiece & 1000w Profile Amp) sounds REALLY good, but I purchased an 85' Silverado and want to put a system in there. Ive decided I want to put the MTX's & amp in the truck, and upgrade the car.

I came to the conclusion I want to get 2 Rockford Fosgate 500w RMS 12" Subs, but I need help choosing an amp to pair up with these. Any help or ideas guys? I know the amp needs to be around 1200-1800w, but I want your help choosing one.

Re: Need Amp to match 2 RF 12" P3s

I would probably say if you want a good one, do kenwood 1500 max watt. amp, or like a middle range Alpine, don't do the high end PDX alpine amps way to much for what you need. But I myself would do alpine, that is what I have an they are awesome. And have it installed prof. will save you a lot of trouble, and the chance of having them blow or burn out, go to like bestbuy or something and ask one of the installers what they would recommend. Way worth it I promise.

Ill look into the Alpine's, now by middle range you mean around 1200-1500w right?

Re: Need Amp to match 2 RF 12" P3s

is there any brands u prefer man im a HUGE FAN of ARC audio look them up its kinda hard to find any dealers being there a smaller company

Rockford and kicker are both good you might wanna consider going Rockford to keep the brand all the same in your car

Ive herd really good things about ORION as long as you stay away from there cobalt series

and of course hifonics is a pretty good brand as well

if you want a cheaper amp id actually go with a power acoustic i really liked mine it was a good bang for the buck amp i always thought

Ive been looking into the Hifonics amps with interest, especially the 1600w model. Do you think this amp will do my P3s justice?

Re: Need Amp to match 2 RF 12" P3s

y would you not use the same 1000 watt amp you have? the subs are rated at 500rms each.. y would you wanna go higher?

Go buy a Class D 1000 watt amp and your good to go

Because thats 1000w Max, thats not what I'm delivering to the subs in RMS with that amp. For now I am using that amp, but I want something that is going to give me the 500w RMS to each sub like they need. My guess is I'm giving each sub about 350w RMS with my Profile.

Double voice coil cuz each coil holds 250w RMS, they are 4 ohm DVC too.

Re: Need Amp to match 2 RF 12" P3s

go to caraudio.com and do research ...amp wise which one you should get? depends on how much you willing to spend ..all you need is 1000 rms mono amp at your ohm rating ...but beware alot of cheaper amps that say 1000rms are either overrated or inefficient...meaning they dont do rated rms or get super hot (power hogs) now your better amp which you will pay more for (not that ebay crap) are very efficient run very cool to the touch and are usually underrated of there rms rating ...
