@Reelfish. I don't plan to compete in any audio organizations. At least not currently. I just want to do the Big 3 for my own peace of mind. I'm currently running an Optima Yellow Top for the dual cycle, and I'm running the factory cables from the side posts and the top posts are running my 4 AWG to my amp and running 55watt HIDs in the high and low beams. I've also done the Quad beam mod where all 4 lights come on when I turn on my highs (rarely have to use them with 55watt lows, lol) Anyways, I plan on running a larger amp/sub combo when I can get around to it. Not sure exactly which amp or subs I want yet, so I still have to decide. I'm not sure how much power it will take, but my goal is to be able to do hair tricks and the cup trick. (for amusement purposes) I don't have a blazer, I have an extended cab with the 3rd door. I currently have the 4 AWG going through my antenna grommet which is where a lot of people route their wire and I've even read a few people were able to get 1/0 wire through there, not sure how because 4 AWG was a pain enough. If I have to I'll drill a hole and run the wire along the frame.
Just out of curiousity do you (or anyone else) know approximately how much power (RMS preferrably) it would take to do hair tricks in an extended cab, or the cup trick? I know the size of the box and what it's tuned to will have an impact on that, but just a ball park figure? So I know what range to look in.
