i bought a car from some guy..he had 2 amps but he took out one...he had the power cable running from one amp to the other. i just recently bought another amp and i was wondering if its safe to do this.he said it was working fine..he was powering 2 10 subwoofers..thats what im planning to do
its safe but its better to run 2 separate wires due to you are wanting to use more power and one wire has a max load that it can handle...you run 2 and you will have more power to each amp
it is safe...but not the best method it really depends on the guage of the wire....best to have a single large gauge running to a distribution block then a wire for each amp comming out of the block to were the amps are. blocks are fairly cheap (usually less than 20 bucks) and safer...plus you get better power flow and 1 amp is not sucking all the power before it gets to the other
