AMP and Subs question
I have 2 rockford fosgate HE2 12" (400RMS, 800Peak) im thinking of getting A ROCKFORD FOSGATE AMP. i was wondering what model would i have to get so i would be running the 400 watss RMS into each sub. a little over 400 is ok just need a model. I dont understand somthing to, the subs run at 4 ohms each, how come all these amps run at 2 ohms, will it work with my subs?

Rep Power: 0 I had two he2 and they kicked azz. I would reccomend the 800a2 and running a 4 ohm load . That would be the best way to go. or get a smaller amp that is 2 ohm stable(mono) and bridge the two subs . either way will work good luck

Rep Power: 0 the 800.2 runs 800Wrms 4ohm mono... or 200Wrms 4ohm x2 .. Not the right power ratios here. an MTX6500D would suit you perfect.. puts out around 800Wrms into a 2ohm load..if you want to stick with an RF amp.. get a Power BD500D.. puts out about 700Wrms.. and the differnce between say 500 and 800 watts.. is maybe 2 decibels..so the little less bit less power will most likely be unnoticable anyways. and the BD500.1 is a class D amp.. it's more efficiant and is lighter on your electrical system. I'd also highly reccomend a 1 Farad capacitor as well..(just for the slightly better bass responce during long sweeps) .5 farad cap would be good too..but spend the extra $25 and get a 1 farad..leaves you room for upgrades.

Rep Power: 0 the HE2 has dual 4 ohm voice coils, with one single sub, you can either wire the coils in parallel and have a 2 ohm load, series 8 ohm load, or you could have an amp that is 200x2 @ 4ohms, but i don't reccomend that. so, if you have 2 HE2's, you could wire them both in parallel and wire them series to the amp, and get a 4 ohm mono load, OR with the 800.2 you could leave them in 2 ohm and run them one on each channel, because it runs 400x2 @ 2ohms. so there are your options for that amp. it is on sale at crutchfield, but i won't post the price

Rep Power: 0 thanks alot for the input, it was very helpful. 1 question, the subs run on 4 ohms each, is it safe if they are ran at 2? also the amp that i mentioned., that would be the perfect one to run my 2 subs at 400 watts each correct? thanks again[IMG]i/expressions/beer_yum.gif[/IMG]

Rep Power: 0 yeah its safe for your subs to run at 2 ohms, email me and i will tell you how to wire them. subs LOVE running at 2 ohms, the bass is deeper, a lil louder, but a slight difference in clarity
