dunno how the **** i did it, but i did, i didnt mess with any of those wires other than the remote wire and the rca plugs, im thinking maybe the frequency made it to that, because when the bass hits hard it jumps, i found it pretty funny and interesting at first, but its really annoying.....anyone else ever had this happen?

btw its a 99 Z

 

does it jump up or fade?
the speedo is electric in our cars. the bass may be draining power and making the needle fall, not sure though

 

the bass makes the needle jump, then it falls back down

 

video! video!

 

i found out that it has nothing to do with the bass, b/c i redid my wireing to make it safer, and swapped sides on the RCA to get them away from the 4GA hot wire, it just jumps randomly, regardless of speed, then it falls back down to zero
