If they barely flicker, then your power is manageable, but if they almost go dark with each bass note, then it's time for more power. This assumes your amplifiers already have built in fuses that are designed to protect them. You should NEVER attach two amp outputs togetherEVERThe voltages will feed back and blow the outputs in a few seconds… Certain competition amps can be daisy chained meaning the output of one feeds the input of the next but thats very few amps that can do that … If you have multiple subs and the amps can run them singly then thats the best route. Unless you really need to, do not get multiple batteries or capacitors. How do you split the low level signal? Some dashboards have clips were you can pop your dash off and other cars have some screws you need to take off before you pop it off and it's the same with door panels. The drawback is that the signal voltage is also split so that each component is now getting a smaller low level signal which may increase the noise in the system.
Remote and RCA wires are always small.
Installing Multiple Amplifiers
I would run one wire for several other reasons as well. Article Info wikiHow is a wiki similar to Wikipedia, which means that many of our articles are written collaboratively. Your thickest or lowest gauge wire should be your main one. For amplifiers that do not have fuse protection you should use a fused distribution block. Follow the general rule:
