[QUOTE="HoneyBadgerRy, post: 8617735, member: 667692"] Your best setup with that equipment will be to wire the amp with the sub woofer preouts from your head unit, and the sub woofer wired up in 2 ohms. You will need to run at least a fused 6 gauge power wire from the battery to the amp but a 4 gauge would be better. On the alpine head unit it should have a setting for sub woofer volume from 0-15 iirc, the setting doesn't amplify the output, only quiets it down, so I would start at 15 and set the amp gain, then turn the setting on the head unit down if its to loud later. The preouts should put out 4v with the sub woofer volume at 15, so that would mean that your amp will put out close to 800 watts at nominal gain, but you will want to measure the volts ac with a multimeter and check before you attach the sub woofer. Lookup "setting amplifier gain with a multimeter" on youtube and it will break it down Barney style. As for wiring your subwoofer use this image to help wiring it at 2 ohms.
