2 ohm stable home audio amp?

[Supergumby5000 5,000+ posts]

I wanna use a 15" type-R in a home stereo setup. Anyone know of an amp that can do 800+RMS at either 2 or 8 ohms?

The only thing i could think of was the behringer ep2500, but thats 1200(or 1400?) x2 @ 2 ohms, and i would only use one channel. Kind of a waste

any ideas?

you can use a car amp you just have to wire it to a computer power supply

I really wish people would stop recommending this.

me too, it models up nicely in 5 cubes at around 22-23hz, so we'll see.

Have you used anything besides type Rs?

Other alpine subs, kicker, RE, fi, sundown, rockford, AA, elemental designs, thats all i can think of off the top of my head.

It will be cascade designs in the new project this coming august.

Indeed. The way to go on this.

Once again, not a good idea.

x2 on the crown. Awesome amps. That Behringer is a P.O.S. and does nowhere near rated power.

Also, craigslist. A lot of old stereo amps put out a lot of power and can be wired to two ohms.

Here's a link to some more good amps: http://directproaudio.com/shop/amplifiers/

There are quite a few that do well over 800 watts at 8 ohms bridged.

This XTi would be a perfect match: http://cgi.ebay.com/Open-Crown-XTi-1000-XTI1000-HiQnet-AMP-Power-Amplifier_W0QQitemZ220393897416QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item220393897416&_trksid=p3286.c0.m14&_trkparms=72%3A1234|66%3A2|65%3A12|39%3A1|240%3A1308|301%3A1|293%3A1|294%3A50

And I'll bet you could get this for under $200

Tell me why it is a bad idea to use a SMPS to power? I design, build, and sell SMPSs every once in a while, used to be my old hobby. For my HT system I use one myself. There is no problem, just don't go by the "max" rating of the Computer SMPS. It will be rather expensive to get one that is able to do what you're wanting, and will be the only easy route to stay on a SMPS since you probably won't know how to use the power supplies in parallel or increase their voltage out to 14.4V.

There is not a problem only if you get a sufficiently large enough SMPS to suit what you need.

PM me for more information if you're interested.

Edit: Crown is the best one out of the above selection.

Edit 2: Going from 120(or 240) to 14V, then stepping it back up to a higher voltage is inefficient though. Only thing I can think of.

Sure. But it'd be expensive and another unnecessary piece of equipment to deal with.
