How to determine ohms for Amplifier?

Hey there everyone.
I have a PowerAcoustik G320-2 (gothic series) 2 channel amplifier and box. I'm in the market for a new 10" sub. Does anyone know what ohm of speaker I should purchase for this amp? I do not have the manual or schematic. (I have searched the web with no luck.)

The amp will be used only for a sub in mono mode.

Thank you.

It appears to be a rather small amp from what I can tell. Can you confirm that it has a 15 amp fuse in it?

Only thing I found is that it's rated at 310W into 4 ohms when bridged. I'd go with a 4 ohm sub since it's very unlikely a Power Acoustik of that vintage will do less.

Thx

Quick thanks to you both. Yes it has a 15amp fuse.
I will purchase a Kenwood KFC-W2511 4-ohm 10" sub and report back how it sounds.

Just trying to get some solid bass punch without spending a small fortune.

Well - I've had the sub for a few weeks now.. thought I'd report back how things are going. Decided to purchase a 4-ohm kicker comp 10" instead of the kenwood. Once I removed the terminal post at the back of the box, the sub sounded great. (Seems to be using it as a port now.) With the terminal post inserted, it sounded pretty bad.

All in all quite happy. Everything together cost CAD $110. Not bad for amp, sub and box.

Thanks for all of your input.
