What size speaker wire should i use for my L7?
I have an L7 12″ running off a Kicker 750.1, does speaker wire size matter? and should i get a capacitor for this system? and also how would you tune a 750.1 for an L7?
Richard and twizted, you 2 did not read the question correctly at all. This is about speaker wire not power wire.
To all, a cap DOES NOT STOP HEAD LIGHTS FROM DIMMING. All 3 of you go learn what a cap does and doesn’t do, because it is not going to add more electricity to the system at all, not now and not ever.
Use 12 gauge speaker wire. A cap is not going to do anything for you. All a cap does is stiffen the electrical current to the audio system, and that is only after the electrical system is producing enough power for the car to operate and all accessories to operate safely. Do the Big 3 upgrade and get a better battery.
