Decaf Posted June 14, 2011 Report Posted June 14, 2011 numbers cant be right, what meters were you using and they are most accurate at 50-60hz btw we got 2600-3000 around 2-2.6ohms
XX7R Posted June 14, 2011 Report Posted June 14, 2011 How does your voltage go that low with a 425a alt and that many group 31's? Ive got a Crescendo bc3500 and all i have is an ebay "Hi Amps" 165 amp alternator, a yellow top in front, normal car battery in back, big 3, and one positive run and i stay in the low 14's to high 13's Voltage drops for music and for burps are totally different stories. The reason i say that is because drops for burps are not " low 1Xs to high 1Xs" Generally drops derived from burps are much more precise. So i am assuming that you don't know your drop on burps. Yeah true.

EclipseChris Posted June 14, 2011 Report Posted June 14, 2011 Yeah that's what I was saying lol. Instead of the YT up front (outside) and the wet one inside, I'd switch em. Either way, sealed or not, I'd rather have a dry batt in the car with me. To each their own. i resolve to be a nicer moderator. Tercel build R.I.P. Eclipse build Old New V-Dub My feedback.

Robert8252 Posted June 14, 2011 Report Posted June 14, 2011 Make a sheet and do clamp it at different frequencies like this It's "possible" your math is right. I had over a 200watt difference with .05 of a change on my DC3.5k. But the aq is supposed to do 800 at 4 ohm iirc. 2013 F150 Crew Cab Old Build Log Feedback 2013 F150 Equipment - Some Awesome Stereo Sound Making Stuff
EclipseChris Posted June 14, 2011 Report Posted June 14, 2011 Yeah true. Didnt think about the difference between burping and just bumping Yeah for my setup (which includes an AQ 3500.1) on music i never see below 13v, but on burps the voltage gets low enough to cut out the volt meter. Its scary... you see 14, then burp, then 9, then blank. i resolve to be a nicer moderator. Tercel build R.I.P. Eclipse build Old New V-Dub My feedback.
fox_racin4 Posted June 14, 2011 Author Report Posted June 14, 2011 Ya thats what i did, going to redo it again this week. IMO ive got more then enough power for this amp lol.... i shouldnt be dropping to 12.8v... going to go over all conections tomorrow and see if that helps 1998 gmc extd cab 12 crossfire C710s 4 SAZ-4500s 3 Singer 400A altsbuncha mids/highs Team Asshole

Decaf Posted June 14, 2011 Report Posted June 14, 2011 use this to keep track http://hebig.sasktelwebsite.net/AmpCalc.pdf only burp to test clamped power... and u need either a peak hold meter or two friends so u can get accurate numbers at the same time u need to see voltage drop, current draw, acv, aca
