finkster Posted July 17, 2010 Report Share Posted July 17, 2010 The only thing a vcm would do in this case is keep the battery charged more often, just keep in minds it is only a 90 amp unit, and you shouldnt expect to have perfect voltage from playing 2500 watts out of it, esp in the heat. and yea, dont put a vented battery in your car. I also hope you dont smoke. Quote DAT 4125------>RE XXX comps active Eclipse cd7000 I serve drunks for a living Link to comment Share on other sites More sharing options...
CheezyMane13 Posted July 18, 2010 Report Share Posted July 18, 2010 I believe that some days your car runs better then others, I have noticed that temperature does effect it some, but I usually charge at 14.4v, up to 14.8v with stock electrical. And some day's that it will be the same temperature It will struggle to get above 14.0v. So it may be due to temperature, but also take in to account your amp and speaker temperatures, and humidity in the air. I have hear instances where high humidity will do something to electrical systems Quote take baby steps, u cant do it all at once unless u have a roll of 100's big enough to choke a donkey 1998 Chevy Venture "Swagger Wagon" Kenwood Excelon KDC-X994 Headunit 3 15" Alpine Type R's in seperate T-Lines 1 RF T1500-1bd for 2 of the 15s 1 RF P1000-1bd for the single 15 3 sets of Hifonics Zeus ZXi6.5C Components( 1 more set to come for Front stage) 1 Hifonics HFi100.4 4-channel amp Stock alt for now (DC HO SPL 400A when funds come in,currently working on buying this) Stock battery and one Optima Redtop for now (looking at XS batteries) 3 15" Alpine Type R's (aka Swagger Wagon Build 1.0) Swagger Wagon Build 2.0 Youtube Videos Link to comment Share on other sites More sharing options...
