GLASSWOLF HELP!
|
PLEASEHELPME Unregistered guest | I have 2 12" Solobaric L7's and a Ported Box with 2 Terminal Cups...How would I wire this with each sub having its own terminal? I want to get a 1 ohm load to go into my Kx1200.1.....please help!! Also, would I then connect the positive with positive and negative with negative from each terminal and then connect it into the amp??? |

IF the coils on each speaker are already in parallel (each coil [+] to terminal [+], each coil [ -] to terminal [ -] ), then the L7's represent a 2 ohm load at each terminal. all you need to do is, like you said, "connect the positive with positive and negative with negative from each terminal and then connect it into the amp" an easy way to do this is simply run the wires from the amp to one terminal then from that terminal to the next. something to consider, however, is the fact that the KX1200.1 is no sissy amp, and unless you are running fairly heavy guage speaker wire, you might want to run a seperate wire from each terminal directly to the amp, doubling the possible current flow, simply to minimise any loss due to the wire (probably by far the most inexpensive part of your install). i'm not sure exactly, but i think 12ga would be plenty. I usually figure, go overkill on wiring, hate to see expensive equipment suffer reduced performance due to a $5-10 problem. |
