Rockford Fosgate T1500-1bd $400 Bought it new at Ultimate Electronics near Ridgedale about a year and a half ago. I have the 5 year extended plan on it - the plan is not transferable, but for a member here I would gladly intermediary if the need arose to have the amp serviced while the plan was still in effect. Since that's just my word, I'm not considering it as adding value to the amp. Selling cause I don't need two 1500w rms sub amps (have an old PPI in the car right now), and I can use $$ more than I can use an amp in the box in the closet. Unfortunately, I don't have the birth sheet any more, but this amp was tested at 1803 watts RMS at 1 ohm when it was produced. This is a good amp. It hits harder than my 1400w rms old school PPI amp that's in my car right now. It's in good shape with box and manual. Willing to demo it for a potential buyer.
