Question about Sony XM-2150GSX Car Audio Amplifier
Often this is related to speaker wiring. Make sure your speakers aren't below the minimum rated impedance for your amplifier; 2 ohms per channel, or minimum 4 ohms in bridged mode. If you have two 4-ohm subs, you can't run them both in bridged mode if they're wired in parallel. If you have a blown sub, it can cause this problem also.
