I've currently got a Fusion Fp-1002 Amp and had that hooked up to an older 400watt rms rockford fosgate sub Which I bought second hand. The Sub seems to have blown and I'm just wondering what's the best 12" sub to suit this amp as I don't know too much aboout ohms and stuff and I've heard people reccomend different types of amps for different subs.

And I'm not really looking to spend too much. Just something that sounds decent.
Here are the specs for the amp btw.
12.6 Volt Power Output Specification
– 100 WRMS x 2 into 4 Ohms
– 145 WRMS x 2 into 2 Ohms
– 285 WRMS x 1 into 4 Ohms Bridged
14.4 Volt Power Output Specification
– 125 WRMS x 2 into 4 Ohms
– 185 WRMS x 2 into 2 Ohms
– 365 WRMS x 1 into 4 Ohms Bridged

Thanks

 

I'm in NZ btw so I'll mostly be looking on http://www.trademe.co.nz/ (similar to ebay) to compare prices.
Here's a few I've looked at.

Note: 1 NZ $ is worth about .50 US$

 

Get a sub that is 350rms that can be wired into a 4ohm configuration: either dual 2ohm voice coil or single 4ohm voice coil.
The first sub listed is the best one out of the ones that you listed that will work.
