i just got it and i wanted to know which way to wire it. it has the black and red wire only.

pretty sure its red to the amp pos and black is ground, then toss it on a switch, my guess

black is negative and red is positive, you need to buy some 16 gauge wire and splice it to make it longer.

Wire to you amp power/ground inputs

i was thinking positive to amp terminal and negative to the amp terminal as well. but i don't know if that's right or safe? but how would it turn on? i know some others come with a remote wire as well bu this one don't.

red=positive

black=negetive

Just wire up to to battery or the amplifier; positive to positive and negetive to negetive.

Then calibrate with DMM.

you answered what was thinking lol will it stay on all the time or only turn on when the amp turns on?

if you wire it directly to amp, it'll stay on forever. you gotta throw it on a toggle switch or use a relay if you dont want to flip a switch every time.

Red to switched ignition and black ground.

so would the Cadence 14 gauge speaker would be fine to use?

it doesnt have a remote turn on, so its different than my volt meter, not sure how that works
