The stock head unit is 4 x 12W RMS @ 0.1% THD (with a tailwind, downhill). Any claims of greater power are full of ummm... optimism.

The only way to connect directly to the Subaru head unit would be through something like the Jazzy mod or via an FM modulator (yuk) or FM transmitter (double-yuk). For the cleanest results, you can use the CleanSweep CL441dsp's aux input to pipe in the audio from a stand-alone HD-Radio tuner. You will need aftermarket amps and speakers, though. Here are a couple of current choices: JVC: http://www.crutchfield.com/App/Product/Item/Main.aspx?g=186650&i=105KTHDP1&tp=134&avf=Y Directed: http://www.crutchfield.com/App/Product/Item/Main.aspx?g=186650&i=60744000&tp=134&avf=Y

Suit yourself, but the factory EQ affects the subwoofer's range as well... but it is true that you would need an amp and new front speakers for a Cleansweep to make sense. http://img250.imageshack.us/img250/5995/volcomparedefeated8et.th.gif The blue trace is at Volume "10" The red trace is at Volume "25" The green trace is at Volume "35" (Yes, the description on the graph is wrong)

If you're having those kinds of problems, we would be happy to replace it under warranty. The failures you describe are not common. Manville Smith JL Audio, Inc.
