I installed the ARC Audio KS 125.2 mini amplifier and Arc Audio Foose FD5025 a few weeks ago...the system rocks, it is very impressive. ARC Audio products are high end and the ARC Audio KS 125.2 mini was made specifically with H-D motorcycles in mind. Installation was fairly simple, I had to fabricate my own aluminum mount bracket and purchase the Rockford Fosgate 10 Gauge amplifier installation kit from Circuit City for about $30.00.
