I purchased a JBL PB12 (powered 250w subwoofer) 3 months ago. I made the mistake of purchasing it from an unauthorized internet dealer, so warranty will be a hassle. And, shipping costs will eat me up if I ship this back to the factory for service. So, I am looking for alternatives.

The PB12 is attached to an Onkyo TXDS696 via LFE.

I appears that my plate amp in the PB12 is bad. It keeps blowing fuses.

I am considering replacing the plate amp, and have the following questions...
1. Is the enclosure and driver in the PB12 worth keeping, or should I scrap the whole thing and DIY?
2. Can anyone recommend a plate amp that matches up with the PB12 enclosure and driver?
3. Since I drive my subwoofer via LFE, is there an inexpensive, low frills amp available?

Thanks in advance for the help.

Default If that doesn't work...

If the above suggestion isn't to your liking, you can also check out http://www.apexjr.com/ they have several sub-woofer amplifiers to choose from. (Different wattages, sizes, etc) Another would be to go to Madisound and look at their KG amps as well. ( http://www.madisound.com/ )
