We suggest powering the OEM woofers with a Soundstream Reserve RS2.1200 2-ch amp ($150 at Crutchfield), with a Wavtech Link2 LOC ($70 at Crutchfield) for a low cost bass upgrade for a HK system. The Bass Boost feature of this amp can get a deeper and louder bass from the OEM woofers without the need of replacing them.

If you are not satisfied with the extra bass of this aftermarket amp setup then replace the OEM woofers with SWS-8Xi and the Soundstream amp.
