Baydestrian Posted October 1, 2010 Report Share Posted October 1, 2010 I got a 1999 Cadillac Seville STS, my battery voltage I can view thru the DIC, was at a steady 13.9-14.2...after bumping with my car off (turned on a couple times for a minute or so) for an hour my voltage now says about 13.6-13.8. My RPMs/Voltage also dip, along with lights dimming at stop lights. Only running 500rms... My dilemma is that my battery is under my back seat so Big 3 isn't possible, unless you can run that alt connection to the positive post under the hood but even then my alt is a bitch to get to. Hoping I can at least do the battery to chassis upgrade but not sure where to connect to, I'll get a pic or two of what it looks like under the back seat. Then the task is finding a good battery that I can use since it needs to be vented. 2015 Mazda 6 JVF Customz 4.0 Proto 15>Wolfram W4500 @ .5ohm 2 Sundown Neo 6.5 + 2 CT Meso Tweeters (Front) x Kicker KS6.5 (Rear)>JL Audio VX400/4i NSB-AMG35 (front) / 40ah Lithium Headway (Rear) built by Erni Audio & Electrical Link to comment Share on other sites More sharing options...
