XX7R Posted June 14, 2011 Report Share 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 1990 Nissan 300zx Twin Turbo - Summer Ride(No system yet, lookin to get it up to 450-500 horse first!)2006 Chevy Malibu - Daily DriverDC Level 5 15", 2 APSM-1500's, 3.88 cu. ft. tuned to 32hz1992 Honda Prelude - SOLD2 18" TC 3hp Woofers on a Crescendo BC3500.1d, 12.7 cu. ft. tuned to 35hz Link to comment Share on other sites More sharing options...

It's not good to have wet batteries inside the cabin/trunk. On topic, 400w at 3 ohms sounds really low Link to comment Share on other sites More sharing options...
corey0928 Posted June 14, 2011 Report Share Posted June 14, 2011 Probably drops so low cuz you idle at 12.8 lol. Heavy ass alt though Link to comment Share on other sites More sharing options...

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. i resolve to be a nicer moderator. Tercel build R.I.P. Eclipse build Old New V-Dub My feedback.

And as long as a battery is sealed it can be in the cabin safely, wet dry gel doesn't really matter. i resolve to be a nicer moderator. Tercel build R.I.P. Eclipse build Old New V-Dub My feedback.

walled01alero Posted June 14, 2011 Report Share Posted June 14, 2011 so, i clamped my amp last week.. AQ3500.1d ( new one ) starting at .7 at 30hz rose to 2.2 ohm made 26XXrms 35hz same number basically then, at 45hz i rose to 3ohm and made 946rms. now, 946rms at 3ohm sounds a bit "low on power" to me? i also peak at 46hz if that helps Yeah the second number sounds wrong. An eight tenths of an ohm won't drop you from "26XX"w to 946w Actually at 30hz u your to 2ohm an made 2580 watts, an 45hz rose to 2.9 an made 396 watts! what the fuck did you just say? i would be willing to go with your math was wrong, or something LOL. Especially if you are getting that much at 2 ohms.. .9 wont make it that low from what you had before. this Link to comment Share on other sites More sharing options...
Slapuhho Posted June 14, 2011 Report Share Posted June 14, 2011 I hated my AQ 3500, so I took it out. They're way too power hungry. 4 18's, low power and lots of gay fur. Team gg Team DOA My Videos Link to comment Share on other sites More sharing options...

And as long as a battery is sealed it can be in the cabin safely, wet dry gel doesn't really matter. 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.
