I have a pair of 12 being driven by my fosgate 500 power and wanted to get a class d amp and want to know which would be best for my setup. The fosgate wheeeew is a moster juice (amperage) junkie and wanted power without the conventional amperage drain. Thanks for anyones help

I say, for the heck of it, look for a 1 ohm stable amp. Hifonics has some nice ones... ------------- ~WAYLAND

Im going to get one this week what wattage amp to get to run the subs they're in a sealed enclosure and rated 400 rms each sub and would the class d be lesser of a strain on my electrical system than my current fosgate 500 power? Thanks for your help wayland 1985

The class D would be easier on your electrical system because they are more effecient than a regular class AB amp. I wouldn't limit yourself on just class D amps though. It's probobly not going to be easy to find an amp that outputs around 800 watts continuous at 1 ohm. You might have to buy a high powered 2 channel instead.

I got the brutus BX 1500 D I have my speakers 4 ohm dual vc's the amps rated at 1500 rms probably @ 14.4 volts is this too much to run cause if I wired subs to 8 ohm output of the amp is now 500rms also would I bee in need of an upgraded alternator I did the big 3 added a cap and have an optima red top my stock alt is 136 but I could buy at autozone a 160 amp for 200. I know class d's are efficient but 1500 rms is still alot of load on my electrical system. HELP Im over my head again in car audio! Oh rms for my subs again are 400 each so 800 total. Thanks for the help fellaz!

the Kenwood KAC X811D is 1 Ohm stable, puts out, and has tons of good features.

If willing to flex from the Class D initiative, US amps has a Class AB that has 800wRMS bridged into 1 ohm. Pretty sure that'd work for your setup, but the thing costs like an MSRP of 950... So may be a bit up there.

I would wire it to 1ohm and use the 1500 rms. Just be careful with the gain. Not sure if those woofers could stand the full 1500.

.... Um.... 400wRMS * 2= 800wRMS. Putting like 1500wRMS(Almost double the rating) fully going into that would, well, good bye? That'd toast it if my understanding is correct. Exceeding the rated RMS is usually not a good idea. Exceeding it by almost double, well, that's just dumb.

roger that but I was going to run it a 2 ohms and I got the hifonics off ebay for 185 shipped brand new from private owner. There are 2 sets of pos and neg on the amp (my bud has one) If I have my subs wired to 2 ohms and use (I know its a monoblock) the two other speaker outs and wire one set to each sub would that increase my ohms from one to possibly 2. I know they are parallel to each other but wouldnt impedance also be raised?
