Well i bought a hk4000d and have heard they are current hogs... im going to be running it at 2 ohms to a 18" BL... probably around 1600 watts (or whatever is safe to run to a BL). I have a stock 130A alternator, and a run of 1/0 to my amp... ill be doing the big 3 soon. What type of electrical upgrades do i need? Would this battery http://www.remybattery.com/Products/Deka-I...9A31__9A31.aspx paired be enough? What about two? A HO alternator is out of the question because apparantly toyota used some special design for my truck (06 tundra) and the cheapest ive found is a 175A for 600

If you definitely don't want to do a h/o alternator try to add a 2nd or 3rd battery of decent size. I don't think you'll have a whole lot of trouble with about 1600rms on 2 batteries, I'd just try it first and see where your voltage sits. I've heard pretty good things about those batteries but I have no personal experience. Seems similar/a little better than a yellowtop- but again thats just comparing numbers. If it drops too low than add as many batteries as it takes - but you wont get your batteries to keep your voltage much above 13v even without a drain, that's really where an alternator would come in. Good luck!

+1, just add another battery under the hood and another 2 in the back..crap man $600 for 175a alt is crazy..
