I thought u meant impedence

how do you check the resistance?like what should it read on the dmm,do i have the amp powered up when i do this?

You want your ground resistance to as close to 0 as possible. The stereo/electrical should be OFF for this. Also check the resistance on the subs/wire coming from the subs to the amp. Again, everything should be off. Tell us what both of these numbers say then we might be able to offer more help.

You also need to check the voltage at the amp & battery and tell us what both of these read a) when everything is off (check battery), and b) when the car is on and the system is on (check battery and amp).

today i redid almost all of the wiring,all i have to do is hook everything back up to the amp and put the sub back in the box.The question i have is does the ground lookin wire on the rca cables have to be hooked up or no?

you might as well wire it to ground. It is the shielding ground to prevent any interference in the signal

is it necessary or no if it is i just have to pull my stereo back out and where would i ground it to since it hooke into the back od the headunit?

I would go ahead and connect it.....wire it to ground like everything else

if the chassis of the hu is grounded well, you can ground to there, or the hu's ground itself

ok thanks,i can do that
