i got a fi bl 15dual 2 subwoofer. im wiring it down to 1 ohm.now for the problem. lets say im wiring the positive terminals together. am i suppose to wire it all with positive wire or can i also use negative copper wire? i used two positive wires and one negative wire to hook up the three positive terminals. is this bad? do i need to make all of them positive silver wires?
however way tou ire them as long as they're placed into the comparable amp they each get that plenty output. So 2 subs @ a million ohms is 1000w rms ea and a couple of subs @ 2 ohms get 750w rms ea
ok well either red or + is positive and black or - is negitive, the problem i have is you said you had 3 positives and one negitive on a dual coil sub,?? if you mean you ran all 3 wires to your amp then its wrong, if you mean you ran 1 wire to your positive,1 wire to your negative, and 1 wire from the other positive and negative together, then you have gone up to 4ohm and not down to 1, you should have 2 positives and 2 negatives, hooked together to make 1 positive and 1 negative as for the wire colors, they sometimes differ so you can tell them apart, providing your the one who screwed them to the amp, i run mine copper positive and silver negative, but each to there own.
Wire is just wire. It alone does not know positive from negative. However, some great problems could lie below the surface. It really depends on what is on the other end of the wire. There may be some problems associated with not following a good wiring practice such as: Creating a short circuit and blowing the amp Putting one of the two speakers out of polarity with the other resulting in lower or no acoustical output. The best practice is to ALWAYS relate the positive or PLUS terminal with the wire with the same designation with the speaker terminal. That way, if you have to do any trouble shooting, you can trace is back and know without a doubt what is connected to what.
Wire is wire. lol. There is no positive or negative wire. A wire can carry either a positive or a negative flow. So it doesn't matter whether you have the silver or black or whatever color wire running, just make sure you connect it correctly to the terminals and amp.
