heating. what could my problem be? i've got each amp powering one sub, at four ohms with dual voice coils. when i turn up the volume after a while at least one of my amps will cut out and go into thermal. i ran 4awg wire from the battery into a ditro block and came out with 8awg the 8awg is then ran directly into each amp. the amps are mounted on the back of my seats and i keep them down, so im pretty sure its not a ventilation issue.. any other suggestions???
