I have an Alpine deck and it has a subwoofer level feature. It goes from 0 to 15. My question is this the same thing as bass boost? I dont want to create more distortion for the sub then I need to. I have the bass boost all the way down on my amp. Im a noob so any positive feed back will be appreciated. Oh by the way I just got my 12" SSD with BP power and HQTS in a sealed 1.1 cu ft box. Running JBL BP 600.1 at 1 ohm. Hope to get anoher amp in the future, but first I'll need a better alternator. THX
