Oh, the price is from SoundDomain.com.

But I am willing to spend aroudn $200. So does that Boss look like a good deal? Is it better than the JBL?

Another question, how does volume control work? Do you set some volume on the amp, and then use the head unit to control the rest? Or does the amp not have a volume control? Or woudl that be a preamp? Sorry for all the quesitons, but I am new to amps and how they work.
