[QUOTE="cerrone, post: 8642800, member: 571342"] Hello guys. I'm trying to install few audio components in my car, consisting of: - two amps each with 4x100W RMS / 4 Ohms (800 RMS in total) with 2x30A fuses ; - one amp 1x500 RMS / 4 Ohms with 1x80A fuse for the sub. The total RMS would be around 1300 W on 4 Ohms. What I want is to do the wiring correct. I want to run just one wiring cable from the battery to the trunk and use the ANL distribution block there to power the amps. I would rely on your expert opinion on: 1. the thickness of the long power wire - 2,1 or 0 AWG for 1300 W of RMS power? What would be the minimum diameter allowed? 2. what fuse size should I choose for the main fuse located close to the battery? 200A or more? 3. What sizes should be the fuses in the ANL distribution block located close to the amps in the trunk? 2x60A and 1x80A (if any)? 4. Common ground through the distribution block or separate grounds cables for each amp? Thanks a lot for the help. [/QUOTE]
