Ok here's the deal. My g/f got talked into buying this amp at best buy a while back for her sub, it's a very nice pioneer amp, but it's a 4 channel. And she is only running one channel to her sub. Is there anyone out there that is interested in trading a 4 channel for a 2 or 1 channel amp? I can get specs etc in a day or so.

Instead of getting a new amp why don't you bridge it into mono or wire it up so the channels run at 2 ohms instead of 4ohms?? Depending on what sub you got and the power on the amp...you should be able to make that amp work for you.

just return it.

I got a Kenwood KAC-626...in excellent working cond...I actually need a four channel amp also. I believe its 100 Watts rms x 2 channel....like 200 watts max into 4 ohms...you could drop it to two ohms and get like 300 watts per channel. If your intrested....pm me

Depending on what you have I might trade you my Alpine MRV-T757 2/1 channel amp. It is up to 750 watts and in excellent condition.

It's a pioneer gm-x334

What kind of sub is she using? What does the rest of her sysetm consist of?

I assume you mean bridge 2 of the channels to mono. How do you "make the amp run at 2 ohms"? What is she is using a 4 ohm driver or something that cannot be wired for a 2 ohm load (DVC 6 ohm etc)...

If she has a 4ohm DVC she could run it at 2ohms. If you can return the amp I would say that is your best bet. Trying to run one sub effectively off of that fairly low power 4 channel amp isn't really possible.

Are you sure it is such a great idea to run that amp at 2 ohm mono? My point wasn't that it isn't possible, it's that we do not have enough info to make suggestions like this. How do we know that the sub she has won't be happy with the 70w x 1 that channels 3+4 would provide? If this is the case, why not keep the amp and she could amplify her front speakers as well? It is too much to guess at which is why I asked what the rest fo her system consisted of...

Ok, here is the deal, it does not work to bridge all four channels, to do that I would need an 8ohm sub. She has a fairly high powered head unit, so she doesn't need external amplification for her other speakers. It's just a waste that her 200 watt sub is only getting 70watts.

No headunit out there, even the absolute top of the line head unit, is going to put out more than maybe 18 watts RMS to 4 channels. You would be amazed at the difference you'd get using that 4 channel amp to run her separates. But...if it is a 200 watt... 4 ohm SVC sub you really do need a different amplifier than the one you have (you already know this) Wish I could help you out with a trade...but I'm happy with what I have sitting in my closet right now, but I'd be happier if I finally put it in my car.

Ok that sheds some light on the situtation. mrsteve is correct that the Pioneer amp would make a considerable better choice than her headunit for amplification. You cannot bridge all four channels to a SVC subwoofer (in 99% of situations, ESX Quantum amps defy this theory).

Is she looking for large amounts of bass? In some situations 70w may be enough for her "200w" sub. What sub is it?? What speakers is she using for fronts and rears if any?
