I'm sure 100 watts will be fine for that sub.
Hi guys, thanks for the input. I agree, 100 watts should be fine. The sub amp has a terminating impedance of 2~8 ohm. I don't turn up the power much since it is in my garage and the sound stays in the garage.
I just finished replacing my OEM stereo system in my Town Car with JVC equipment, but left the factory speakers in. They are JBL speakers and the only speaker that has gone bad is the sub. Got tired of not being able to listen to my android in my Town Car. I did my Cougar a few years ago with JVC and Blaupunkt equipment. (just sharing)
Thanks again for the feedback!
