I just bought my S2000 today, and it has a Panasonic DFX572U head unit along with a JL Audio sub and two soundstream van gough(sp) amps. The guy I bought it from is going to send me the manuals, but I don't know how long that will take. I am trying to figure out how to turn up the bass. He showed me, but I wasn't really paying close attention If anyone knows how I might be able to do this, or perhaps where I could find an online manula, I would greatly appreciate it!! Thanks! I will get some pics after I clean her up
