Speakers are pulsating

[trinixtc]

I tried searching and i found things close but no luck. I had my subs working good and i decided to change up the speaker wiring. bad idea, when i turn on the car the sub start to pulsate in and out constantly. just thumping even at 0. i unplug the rca's and it goes away. the mid amp are fine so i tried there rca's same thing. i am running 4 12 pioneer primeer 3000 subs and 2 ma audio hk-802S 4400 amps. any ideas? thanks.

What wiring did you change? Are you using a stock head unit btw?

rca inputs/outputs on amp/headunit?

check all the wiring from amp to sub...

also the ground/power/remote

I know this happened to me with my mids. I was in a hurry and found out i put a trim piece screw right threw the speaker wire. Instant ground. Just check the wire it is grounding out somewhere
