I have two 10" Infinity REF1050W subs in a vented enclosure:
rated 250W rms at 4 ohms, 1000W max power (each)
I was wondering what kind of amp would be good to power these.
My friend has a Pioneer GM 5200T 2 channel amp:
125W rms x 2 (at 4 ohms), 190W rms x 2 (at 2 ohms), 760W max power

Would this be an adequate amp, or would it not be powerful enough?Is there a way to wire it to get more power?
If it's not ideal, what other kind of amp should I get?

if only i could delete this post...

Nope, i would not want to run subs off half rated power from that 2chan amp. for future reference, the main rating you need to look at is RMS, peak means almost nothing.

500w-600w @ 2ohm would be optimum for your subs, there's plenty of good amps that can be found for around $2-300 that'll put out a the right power for your subs.

The amp i use would work well for them, or anything similar. http://www.alpine-usa.com/product/view/mrp-m500/

My buddy uses one of these, it's pretty nice- http://www.sonicelectronix.com/item_...on-XH7110.html bit more power than you need but more is better than less.

I have a mint Zed Kronos that would be perfect for your application

>250rms x 2 @4ohm

So I found someone selling a Memphis M-Class 16-MCD1000 1100 Watt amp for 200$ that I think could work.

That amp is a good match power-wise for your subs and Memphis is a better than average quality brand.

As long as you set the gain and subsonic filter controls correctly you don't have to worry about blowing them up. Page 9 on the Owners Manual has a good explanation of how to do it.

If its working properly its sounds like a decent deal...

Hmm, or I'm also able to get a 2-channel Autotek AT1000 for 100$. Which amp do you think would be more suited for my setup and the best price/quality-wise?

you get what you pay for.

I would be skeptical that a $100 amp will put out those actual numbers and be reliable at all.

The memphis looks like the better option between the two listed.

and as long as it is set up properly, you never have to worry about an amp 'blowing out' your subs because of too much power.

I'd also go with the Memphis. It'a a great match power-wise as you have 500rms of subs and the amp claims to bo 600w rms at 2ohms.
Once you have it installed, be sure to carefully set your gains!!

Personally, I wouldn't even look at the Autotek unless you need something to run your front stage.

The Memphis is rated at a 2ohm mono load which is what you have...the power is more than adequate for the subs and the extra $$ for it will pay off in the long run.
