[QUOTE="CarAudioNewb!, post: 7695417, member: 640585"] hey guys quick update, im at a coffee house using internet there so i can post this quick, but my lights are better after i set the amp with my DMM and volt meter i installed is staying pretty steady on 14.5 to 14 on heavier hits , system still isnt blasting but volume is up high and there is a lot of bass coming out that see my rear view mirror shaking. but I was curious so I took my dmm and took a reading from my starting battery and then the battery in the trunk the shop installed to help power the sub and amps, and basically when the car is off, its reading both batterys as one, the reading was 26 I think point something and in the high 30's with the car on. Did they wire the trunk battery wrong because why is the reading from the starting battery so high if the trunk battery isnt in line with it, it has to be set up as part of it for that to happen right? is this bad and what could be causing my issues, I want the trunk battery to mainly act like a better capicator its a ct600 so its not a huge battery but Im going to re wire it tomorrow if you guys think it should be different and if this is what is causing some of issues because the alternator is seeing more in terms of it cause they are reading together? this is my first system where I had a second battery installed so any help id appreciate it. there is a seperate fuse for the trunk battery too, and I was told an isolator to and it is grounded in the trunk.
