[QUOTE="daboyfrumdabx, post: 7150696, member: 617760"] Big 3 is upgrading wires in your electrical system. Typically done with 1/0, but 4awg will still be an improvement. You run a wire from your [B]alt(+) to your batt(+)[/B], from [B]batt(-) to ground(-)[/B], and your [B]engine(just pick a bolt) to ground(-) or batt(-)[/B]. Search it on youtube, there's plenty of vids on there explaining it farther and it will give you a visual. You leave stock wires in place, you just add these new wires. It allows current to flow more freely and takes strain of your charging system. What I meant about how you tested your sub, is that there is no way to wire that sub at 4ohms. You either had it wired at 2ohm or 8ohms for testing, unless you only hooked up one voicecoil(I hope that's not the case). I just want you to read up and learn these options so you don't mess something up when you really install it. You should be wiring at 2 ohms like this: [IMG]http://www.rockfordfosgate.com/rftech/woofer_wizard/1_4ohmDVC_2ohm.gif[/IMG] [/QUOTE]
