t4004 or t8004. possibly a t5002. let me know what ya got. only a rockford power series though. I need one to match my t20001. I'd like to set up a trade with something in my sig or cash.
How many speakers are you planning on running with the new amp? If 4 speakers try the RFT3002. Rated at only 50x2 @4ohms but usually throws out 200(+)X2 @4ohms. So 100 watts to each speaker.
