Lsufan51 Posted July 24, 2015 Report Share Posted July 24, 2015 I found this battery online. I was wondering if it would be good for my system. I'm running a fosgate t2500bdcp and a fosgate t600-4. My alternator is 140 amp stock alt, with big 3 upgrade. http://m.oreillyauto.com/mt/www.oreillyauto.com/site/c/detail/SSB7/34EXT/07053.oap?year=2008&make=Chevrolet&model=Impala&vi=1440294&ck=Search_agm+battery_1440294_697&keyword=agm+battery Link to comment Share on other sites More sharing options...
reedal Posted July 24, 2015 Report Share Posted July 24, 2015 I wouldn't. Don't look at cranking amps, look for aH (amp hours). For that amp combo, if you're not going to up your alternator (which would be much better than adding batteries) then I'd get 3-4 100aH AGM batteries, and a charger with a trickle charge setting to top them off every night because that alt won't do it. You should get an alt that outputs at least 200A at idle though, that 2500 is going to need some juice SMD Tool Map https://www.stevemeadedesigns.com/board/topic/193176-smd-tool-map-new-november-2014/ Build log https://www.stevemeadedesigns.com/board/topic/197217-reeds-03-tahoe-hat-sqaq-singer-xs-shca-cockbox-80prs/?page=32 Link to comment Share on other sites More sharing options...
Lsufan51 Posted July 24, 2015 Author Report Share Posted July 24, 2015 I plan on upgrading the alt pretty soon. I'm just looking for a way to keep my volts up in the mean time. Link to comment Share on other sites More sharing options...
reedal Posted July 24, 2015 Report Share Posted July 24, 2015 If you're saving up for the alt and already have money for a good AGM 100aH+ battery, keep that money and put it towards an alt. that's my advice. Until then, keep the volume low to keep your voltage up. Who are you looking into for an alt? What year/make/model vehicle is it?

Lsufan51 Posted July 24, 2015 Author Report Share Posted July 24, 2015 It's a 2008 impala 3.9 v6. Even with my volume down it still will get down into the high 10s. Around 10.8. I've got some wire coming for the big 3. I plan on doing that next weekend. Link to comment Share on other sites More sharing options...
Lsufan51 Posted July 24, 2015 Author Report Share Posted July 24, 2015 I was looking at the mechman alts. They seem to be the cheapest for my car and I've heard good things about them. Link to comment Share on other sites More sharing options...
Miguels Posted July 24, 2015 Report Share Posted July 24, 2015 He dont need 3-4 batteries for that amp. The biggest one you can fit under the hood. 1 D3100 in the rear and the money you would spend on the other 2-3 batteries could go towards a 270a 6 phase hairpin alternator. my logshttp://www.stevemead...-my-new-set-up/my blow through loghttp://www.stevemead...future-updates/ 96 ss http://www.stevemeadedesigns.com/board/topic/164094-96-impala-ss-build/ Link to comment Share on other sites More sharing options...
Broke_Audio_Addict Posted July 24, 2015 Report Share Posted July 24, 2015 1 d3100 is more than enough for that setup. I agree with Miguel get one good batt for the rear an agm for under the hood and buy a decent h/o alt and you will be fine. That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.

reedal Posted July 24, 2015 Report Share Posted July 24, 2015 That's with an upgraded alternator. I stated it before he said he was intending to. With the amount of people who say they don't want an alt or can't get one, I took the info provided and made a suggestion based on an amp that does a few hundred more than rated. With a HO alt, yes, one AGM up front one in the back. And if you're still dropping to the tens with the volume down then you're not turning it down enough. And make sure you use the proper tools to set the amplifier gains SMD Tool Map https://www.stevemeadedesigns.com/board/topic/193176-smd-tool-map-new-november-2014/ Build log https://www.stevemeadedesigns.com/board/topic/197217-reeds-03-tahoe-hat-sqaq-singer-xs-shca-cockbox-80prs/?page=32 Link to comment Share on other sites More sharing options...
