[QUOTE="weeeugene, post: 600163, member: 557763"] A friend of mine plans to set up a car audio system outside his car for an art/sound installation project (don't ask). And i've been asked to help him set it up. Got a quick question on fusing the system will be running off a car battery and will feature the following amps. Sounstream 360.2 (2x90W with 1x40A fuse) running dynaudio GTs Lanzar Opti500.2 (2x500W@4ohm with 4x40A fuses) running 2 x RF Punch HE2 15s in stereo @4Ohms. Here's the question: For the in-line fuse near the battery, i know from searching posts that 125A fuse is ideal (using 4AWG wire from battery to distribution block). I currently have a 60A fuse from a previous project. What are the consequences of using the 60A fuse (cos he's in a hurry to fire it up)? The distribution block will run an 8AWG run to each amp (less than 10ft). Both are fused there with a 30A fuse. Again, what are the consequences. Basically i think it should be ok because i really doubt he's going to draw more than 30% of the power from the Lanzar sub amp since he's running them with a single set of comps powered by the 2x90w. Turn the amp up any more and the bass will drown out the comps. so guys, whadyathink? Thanks a bunch [/QUOTE]
