4 8" subs one is working harder than the others??

[manny1337 10+ year member]

I just got done installing 4 new re 8's in a 2.0 cf 35hz box. one of the subs is working harder than the other three. i used rockford wiring and wired them to 2ohms total load (each driver is dual 4) i dont get why this is happening. this one sub clips and the rest are fine. is it a bad sub? or did i wire something incorrectly?

Could be bad coils on the one.

Take the bad one out and check the coils with a DMM.

btw used this wiring

lowes walmart anywhere really

and just put it on the ohm/resistance setting

if your coil is good it should show either 4 or 2 ohms etc. whichever your subs are supposed to be

Swap the wiring around from the issue sub to another and see if the issue follows the sub or the wire run. Maybe you have a short or issue with the wiring. Also might try changing location of the sub if its near a port opening and maybe unloading, I've had that happen before.

the sub is actually more away from the port then the other 2. i guess ill go out and buy a dmm and check the coils then ill try the wiring if the coil is alright =) thanks

i bought a dmm and set the resistance to 200 and each coil is reading 3ohms i believe. it jumps around a little bit but not much. its dark out now so i cant do much more but i was thinking of rewiring it. soldering the connections right to the sub instead of using connectors =/

anyone else got any idea?

okay well i switched sub pos with another one and now they all seem fine? that was pretty strange. thanks for the help though

Yea..... i would definitely double check all your wiring.
