I won a Kicker KX550.3 on Ebay the other day. I am going to run my sub which I already have @ 2ohm. It is a Kapp Perfect 10". I am looking for a set of components to go along with this. $150.00 and under. I kow the Kappas are harsh, what is the consensus of the Reference line? Any other suggestions would be great. The PG RSD's are not an option. Thanks.
