Guest Posted October 29, 2009 Report Share Posted October 29, 2009 whats the voltage of the battery when its been sitting for a few hours after you shut the car off? i would buy either a new battery and do the big 3 or buy a 2nd battery and do big 3. cant autozone "test" the battery for you to see if its good?

Austin175 Posted October 29, 2009 Author Report Share Posted October 29, 2009 well idk about a few hours after but when i start the car it goes up to like 14.5 or 15 then after bumping it gradually goes down an down Quote kia spectra 4 door HU-a kenwood kdc-692x optima red top under the hood ( kinetik battery or powermaster in the back ) Iraggi 260amp H/O alternator 1 set of knu kandy 1/0 guage wiring kit ( 2 more sets coming ) front speakers - back speakers - 2 12" lv 4's with lvl 5 softparts ( going to be 4 in near future) Sundown 3500d( going to be 2 sometime ) i have boughten from - Bass14(smd), ddbump(caraudioclassifieds) Link to comment Share on other sites More sharing options...
missinglink Posted October 29, 2009 Report Share Posted October 29, 2009 well idk about a few hours after but when i start the car it goes up to like 14.5 or 15 then after bumping it gradually goes down an down Sounds like to much demand for your alt and not enough storage to help cushion the draw If your jumping up like that from stock voltage at start up chances are: 1)the batt's going bad and loosing and/or not holding charge. 2)your alt my be going out 3)To much demand and alt is just can't keep up. To rule out the battery 1st check its (resting voltage) use a volt meter first thing in the morning before you ever start your car (do not charge battery over night then test) Simple #'s are 12v dead , 12.5 55%full , 13v full , if your pumping 14.5 to 15 volts into your battery it should be (resting) a solid 12.9+ Your car will try and compensate for a low battery by raising voltage at start. It drops lower with lights on at night just because the demand is greater on the alt and prolly just can't keep up. Hope this helps shed some light on things MLA Quote missinglinkaudio The United States Marine Corps.

Iraggi Alternator Posted October 29, 2009 Report Share Posted October 29, 2009 Sounds like you may need a battery and an alt. Dropping to 12's indicates needing an alt.. dropping to 9's indicates needing both. How much power are you running on your subs? Quote Link to comment Share on other sites More sharing options...

SojiaRaggs9000 Posted November 1, 2009 Report Share Posted November 1, 2009 Did you try adding a battery in the trunk as well as doing big 3? reason I ask is because I had a similar problem. I had 3000watts @ .5 droping my front battery down to the 9's. So I add a XS D3100 in the back and took out the 4ga and reran everything with 1/0 wire. Now my voltage on both bats are 14.5 -14.45 when the bass is hitting hard.
