Low Voltage help

[robi523]

On the inside of the beast is the factory 8" head unit as I like the connectivity/integration of it. I didn't get BOSE system because I prefer aftermarket. I have JL Audio C5 6.5" components in the front and C3 6.5 components in the rear. I have the JL Audio flex integration unit as long as the Tweak digital processor. I put 2 JL Audio 10W6's in a FOX ACCOUSTICS ported box under the rear seat which are enhanced by an Audio Control Epic 160. Pushing everything is a JL Audio XD 1000/5 and a JL Audio XD 600/1. Foreseeing some issues with power I went with a dual battery setup and ran Dual Optima Yellowtops. It sounds GREAT, however I am up against a wall with the PCM. With the voltage so low when it goes to rest I can't run hardly any volume on the system. It's annoying the hell out of me and I've only had the stereo in a week! The amps cut in/out constantly. I ordered a Mechman 270 amp Alternator, but with the PCM the problem will remain. I have read that with a single Optima the high load trick doesn't work. Is there any way to disable the PCM without turning lights in the dash on? Can I install some sort of resistor to trick it?

Its evident that you know and like fantastic sounding audio. I will recommend looking into XS batteries for your 2 batteries. I have seen too many issues with optima to recommend them to clients anymore. XS is becoming an industry standard on high end builds.

 

Sadly I personally have not done much with the new body style so I will ask some co-workers because I haven't seen anyone complain on the subject matter yet
