New Amp to Update Old Realistic 12" Passive Subwoofer?

[PowerSurfer]

Have a working older Realistic 12" passive subwoofer, marked Cat# 40-4050, and I'm wondering if it's worth upgrading to an active sub, using a plate or external amp. This would be for use in a home theater setting, to fill out the bottom end of some bookshelf speakers. I'm not looking for room-shaking bass. I just want to add a little more than what's coming out now, and to add more control. The sub is rated at 100W. I figure it's probably not worth spending more than $100-150 on this. I'm fairly handy and understand basic wiring.

Forget it, a waste of time and money.

I wouldn't put a penny in to it. If you are budget constricted get one of the 10" or 12" house subs (Dayton series) from Parts Express.

I agree,but If I had tools and space I'd buy Dayton Sub kit and build one myself.
