Would like to know the gauge of your wiring to the amps and the specific models of your amps and speakers. 2) Do a big 3 upgrade and check that the alt is charging. 3) At the end of the day you will be needing a battery and alt upgrade. DON'T play the system with your voltage low or something might blow, get something like this while you save up for those upgrades: http://www.walmart.com/ip/Schumacher-SC-300A-3-Amp-Fully-Automatic-Electronic-Tr ickle-Charger-and-Maintainer/15167353 Bear in mind that this is a temporal solution and likely the battery will fail. |
