hello, I have a Yamaha RX-V1500 receiver and a pair of PSB image 4t towers right now and I am wanting to use one of my 12" IDQ subs as my subwoofer for my system. Does anyone know where I can buy a subwoofer amplifier that I can hookup to this receiver? Something that is 200 watts RMS or MORE @ 4 ohms?? If anyone could help me with this with any info or links or any kind that would be great. Also is there any reason that someone shouldnt use a car audio sub in home audio application?
