i have messed with the settings on 2 different head units, theres no change. the current head unit doesnt have as many settings as the other one but it has the basics, the other one has the same but also HPF and LPF settings. the sub is a pioneer 12inch 800watt and the amp is a pioneer 800watt. originally that amp powered a 12inch alpine type r but apparently those are made like crap (or i abused it) because i melted the wires coming off the voice coil. i replaced it with the pioneer sub a year and a half ago. fuses are good. 6ga fused power is good and also brand new, 6ga ground is good and brand new, brand new RCAs too. RCA is ran down the passenger side, power and turn on wire on drivers side. the only thing i havent checked are the two fuses plugged into the amp (30 each) because i assumed if those went bad it wouldnt work at all.
