i have a fatboy 1x4 being pushed by a galaxy 959 in a 2009 nissan altima (550cca batt & 110amp alt). running a 15' run of 4AWG fine stranded power wire with the cold wire hooked to the neg. of batt. all doors, hood, trunk, radio and box grounded, going out to a wilson 5k trunk lip mount antenna (lmr 240 coax) with swr's 1.1 & 1.2 on 1 & 40. meter is showing 600w PEP with a whistle. other locals are getting 750-1000 out of this box. have dk set to 2w on radio and 150 w/ box. was told that maybe the radio isnt pushing box hard enough. when i turn up the variable power all it does is dk higher but swings to 500-600. was wondering what i can do to get more out of the box aside from changing alt and adding additional batts. thanks for the help.
