Question about Alpine MRD-M605 Car Audio Amplifier
If your deck is aftermarket; Does it have a dedicated Subwoofer output? if so, check the control in the deck (sub gain). If you are using a factory radio, and a high to low level adapter (speaker wires to RCA), it may be bad (not too uncommon) or check your fader front/rear any difference? Otherwise, you have one of two problems. A bad preamp in the deck or a bad pre amp in the amp. Both are fairly uncommon. More than likely it's a setting. Hope this helps

Could also be the RCA's also maybe your amp reset if a one point the battery was disonnected thereore your gain went back to a lower V setting
