what i suggest doing tomorrow, or when you get the time is.

taking your DMM (voltage meter) and hook it up to your amps pos and negative. play it at full tilt and watch the voltage.. if your voltage is going up and down like a low rider, you got your answer on what you need to do.. if the voltage is staying steady or above 9.6 volts (where the amp protects at) then it is an issue with:

RCA

deck (hu)

amp

wiring

09 Civic EX

KDC-X395

(2) SKAR Audio VVX-12

Skar Audio SK-1500.1

4 cu ft @32 (new box and more port soon)

Firing Forward not sealed off

Stock 80 Amp Alt

Big 3 In 1/0 Knu

2 Runs To The Back 1 Pos 1 Neg In 1/0 Knu

DD-1'd 13.8v drop

and when you mean going up and down does that mean a bad ground?

sorry for the late reply.

well it could mean a few things including a bad ground.

could also mean the batt is bad

i would do what the other guys are saying, check/redo the ground, sand EVERYTHING off until you hit straight metal and bolt it down
