Ok I have two amps (te1501d and ta81001d) with one 0 ga. running into a distribution block wich turns it into two 4 ga. and are grounded separately. When I turn on one amp at a time they sound great, but when i turn them on at the same time the woofers show excursion but dont sound half as great as one at a time. Do I need to run the remote from the head unit into a relay or is the 4 ga section the problem. Please help thanks.
