Should I rewire my car

[southpoleman69 10+ year member]

I've got that all figured out, mines to be set at 40, 1600x1 sq rt=40 volts. I'm not really familiar with a dmm. i understand how to set the gains and check resistance and whatnot, but on the dmm, what does it need to be set to for me to properly get a 40 voltage reading for my gains

Your lowest AC setting that's above your target, so, it's sound like AC200v is your lowest? Also, they are known for a bit of leeway on ohm ratings, especially cheaper ones. Sometimes speakers aren't RIGHT at 4 ohms. you're in the ballpark though so you're fine.

so to tune the amp i keep the dmm switched on to 200 ohms? yes that is the lowest for the ohms setting. The speakers i figured were a little off, so that wasn't a concern.

Unrelated note, i ordered all my knu items, and then realized ha stupid me i didn't order any speaker wire to go from 4 channel to the deck.

btw thats the one i have, it may be crap, i just borrowed it from my stepdad, so if its garbage i may end up just buying one anyway. but its got many different settings and not being familiar with a dmm at all, other than testing speakers, it has me a little confused is to keep the setting at 200 ohms to set the amp gains as well.

The meter should be set to AC volts for gain setting. For mine, the lowest it goes is 200ACV, so that's what I use.
