[QUOTE="91RS, post: 8659541, member: 675752"] I just bought an Audison 5.1k and I have two questions about the wiring. The owners manual says it can take 2 gauge cables but 2 gauge isn't very popular, it's either 0/1 or 4. Since my battery is in the trunk and my cables might be 5 ft. long at the most, the chart Crutchfield has on their web site says I can use 4 gauge. Does that seem reasonable since it's such a short run? I have a bunch of Monster Cable 4 gauge already so that would be great if I didn't have to buy any more cable. My other question is that this amplifier has a provision for a capacitor. The owners manual (unless I missed it) doesn't say that it is required. I was always under the impression that if a capacitor is needed then the electrical system of the vehicle isn't up to the task. I haven't noticed any issues with my current amplifier (DD D5.1000). Should I be ok without it? Thanks.
