Why is my system playing at 8-10 Ohms instead of 1 Ohm like it should be?

Might be using the wrong Dmm or something wrong with it..

[CJ18]

Touch the leads of the dmm together and read what the starting resistance is. If you get anything when you do this you have to subtract that number from what you get when you test your sub ohm load.

Its the right DMM but it looks like its not good enough to tell what the ohm is when its playing. I think its just my dmm because i just checked again and it reads 1.7 ohms when the systems off

your speakers impedance changes and fluctuates when your system is playing ... the impedance will also change if you just push the speakers in ... you want to read the ohm load with system off no music playing subs just sitting idle

here's your problem

whenever testing for resistance. touch dmm leads together, find value 1. measure coils, find value 2. subtract value 1 from value 2, final resistance found.

You can't check it while it's playing. Accurately anyway.

what he said. when you measure resistance with a dmm the dmm sends a small ammount of electricty through whatever you are trying to measure. if you measure resistance while your circut is livethere is a huge countervoltage on the meter, big countervoltage= blown up meter. i see it happen all the time. you might have gotten lucky and your meter might have survived. if so always remember never measure resistance of a live circut.
