[QUOTE="ExtremeODD, post: 8773844, member: 564981"] Why drop $200+ for 25-300a when $20 can get you an easy 140-160 (or double that if you nix the A/C compressor) and when its not enough there are kits to get an easy 200 out of a ad244 or dr44/g. Local pick it yourself yards sell cheap and its easy to find a late 2000/early2010 decked out escalade or denali with one of the following rpos K68 = 105AMP KG7 = 125AMP KG8 = 130AMP KG3 = 145AMP KW1 = 160AMP Hell, ANY fullsize chevy with a 4.3/5.3/5.7/6.0 should have something worth grabbing. Personally I got my dr44 off a yukon denali and luckily it was a 2 pin connector. The units with 2 pins can be pwm controlled for their output using a cheap af pwm generator off of amazon/ebay. Just send one of the pins 128hz and a duity cycle of 6-94% to get 11.5ish-15.2v. Grabbed both a dr44 and dr44g, one with the 2 pin plug, one with the 4 pin, 15ft 4g wire, pcm and electric fan for just under $50 at my local yard. That alt is enough (along with a rear mounted h9 agm) to keep the system going full tilt for 30-60 mins nonstop driving before the voltage starts to sag a little. [/QUOTE]
