ok so i just installed an A4004T, bridged (200 watts @ 4 ohm) per sub. im running it to 2 10" eclipses that are rated at 200 rms @ 4 ohm. my problem is that only channels 1 and 2 (bridged to form 1 channel) are the only ones that seem to work. channels 3 and 4 (bridged to form channel 2) dont wanna work. iv switched the speaker cables to see if it was the sub that was malfunctioning, but it wasnt. both work, but they have to be connected to the first channel. that mean everything is wired correctly, sonce both speakers work which leads me to think something is wrong with the amp? could it have come defective from the factory??
