Audio System POWERE FREAKOUT!!! Help!!
Hey all,
I got a doozy for you all out there. I own a 1997 mitsu mirage. I got a carputer installed and infinity kappa speakers all around running from an infinity 4 channel amplifier. Just recently, the AMp has been in protection mode. I checked the voltage and it appears im getting 5.5 volts into the amp, but 12V coming off of the distrobution block. Here are the facts. . .
POWER
- Stock Battery
- 4 Gauge power wire ( fused at battery) ran back to trunk fused distrobution block
- Distro block feeds power to computer and amp on seperate fused channels
- Remote wire extended from front of car back to remote input on amp.
- Remote opus wire plugged into amp remote slot
GROUND
- Gold plated Stinger Grounding Block installed to Chasis of Trunk.
- Computer and amp recieve ground from there
PROBLEM
- Amp constantly in protection mode
- Worked fine for the past 2-3 months
TROUBLESHOOTING DONE
- Measured 5.5 volts from + terminal on amp block
- Measure 11.9 volts from Distrobution block
- When remote wire is disconnected from amp, measure 11.9volts at amp block
- Hooked + and - wires of amp directly to a 2nd battery using same remote wire. ( Measured 12.1volts at amp, amp worked correctly)
EQUIPMENT
- Newly ran 12gauge stinger OFC speaker wire direct to speakers
- 4Gauge stinger power cable, only breaks at fuse and distro block
- Rockford Fosgate 8 Gauge power and ground wire to comp and amp
- Stinger fused distrobution block
- infinity 7540A 4 channel amplifier ( brand new, 1 month old so far)
- infinity kappa perfect 6.1 components(front) + Infinity kappa 4X6 Plates (rear)
VEHICLE HISTORY
- About 1.5 years ago I started getting some weird power problems like my reverse lights being always on. I simply took the bulbs out to hide the problem.
- Then, my E-brake notification light is in the always on position now.
- Right before the amp started to go into protection mode, i had the battery light on in the car for about a week or so and turning on lights and electrical eqipment would wreak havoc on the vehicles internal lights and would sometimes kill the engine and force me to jump start the car.
- Anybody got any idea on this one?
