Great amps for sure!

The only ground left to check would be the amp ground on the frame tucked up in a tight spot. I'll try to re do it this weekend when I have time. Work and school sucks lol

ok i have a problem with my voltage. i can't seem to find the problem so i was wonding if anyone could help. I have a 250 amp alt with 2 runs of 0 gauge 3 batteries one is 100ah and the other is 139ah. Plus the blue top under the hood. The amps are a sundown 2500 on 4 12 skars and a sundown 1000 on 2 skar 8s and a old school Rockford 1500 on the highs. But at full tilt I drop to 11.8v and driving 12.2v idk what the problem could be. all grounds are to the frame and i did the big 3 all 0 gauge. all batteries tested fine. If u have any suggestions please let me know. Thanks!

Well just tried the 0 gauge run from from front to back and it helped at first but still drops so low. And once I stopped playing system voltage didn't climb higher then 13.4 And a question, would one bad ground in my whole system cause this much of an issue.....? Been researching a lot and found mostly the same stuff that could be causing the problem but went over every ground up front and shaved and re crimped the connections. Still no success.....

Wow look what I found lol. Dosent really make sense to e but here it is SOME 2003-2004 CROWN VICTORIA POLICE INTERCEPTOR VEHICLES MAY EXHIBIT LOW CHARGING SYSTEM VOLTAGE AND/OR A DEAD BATTERY AFTER PROLONGED IDLE WITH ACCESSORIES ON. TO SERVICE, REPROGRAM THE POWERTRAIN CONTROL MODULE (PCM) TO THE LATEST CALIBRATION LEVEL USING WDS RELEASE B29.9 OR HIGHER. THE NEW CALIBRATION RAISES THE BASE DRIVE IDLE FROM 544 TO 600 RPM, NEUTRAL IDLE REMAINS AT 800 RPM. THE NEW CALIBRATION ALSO DETECTS WHEN THE BATTERY VOLTAGE DROPS BELOW 11.8 VOLTS DURING AN EXTENDED IDLE AND WILL RAMP THE IDLE SPEED UP TO MAINTAIN BATTERY CHARGE. IN NEUTRAL THE IDLE SPEED WILL SLOWLY RAMP UP TO 1100 RPM. IN DRIVE THE IDLE SPEED WILL SLOWLY RAMP UP TO 800 RPM. THE IDLE SPEED WILL RETURN TO THE BASE VALUES (600 IN DRIVE, 800 IN NEUTRAL) WHEN THE BATTERY VOLTAGE RETURNS TO 12.5 VOLTS OR HIGHER.

Yeah it will work. Whats the amps? And brand? And price?

Looks right what's the plug look like?

How much and will it fit my 03 Vic?

Yes lol 14.1 idle then 11.8 at idle at full tilt.

Added alt ground and it seems to help voltage rise faster after the bass hits but still dropping to 11.8 at idle. I was looking into a voltage regulator but can't seem to find one. I need one for a ford 6g. If anyone know where I can get one that would be great!

iv re crimped all wires and shaved every connection again and it has something to do with my charging system or batts. today went to the beach and was at full tilt for about 20 min. was at about 11.8 to 12.2 as usual but when turned off system voltage never got higher then 13.4 where it supposed to go back to 14.1 so its got to be the voltage regulator or not enough bat power. i just can't find it. and i was going to add the alt ground but stereo shops were closed today. will do on my way home from work tomorrow.

Ok I'll try the alt ground tomorrow and post if anythings better

Ok yeah i understand that, ill try that tomorrow and see if i get somebetter voltage. Also i was researching a little bit right now and saw that if a car is a uni body u should run ground wires from front to back batterys so they all share the same ground. Have u ever heard that? I always thought a ground should never be longer then 3 feet.

Yes i have the 6g and i have the 0 gauge wire to the battery from the alt but didnt know i should upgrade the ground off the mounting bracket. Should i use a 0 gauge there also and ground it to the frame where the grounds are for my battery and engine ground.

Where can i add or upgrade the ground for the alt? And how would i do that?

i was looking into doing that, getting the xs power one that you can set the voltage yourself. the seems to be the logical answer that the voltage regulator isnt woking with my h/o alt.

no i was saying 2 of my batterys that are not in my car anymore i sold them, autozone said they were bad but they were fine.and edouble i belive that is most likley the problem beacuse i seen my stinger voltage meter go to 16v something once for 10 sec and was blinkning and over the weekend my car wouldent get higher voltage then 13.5 driving with system off. just a whole bunch of different issues.

i had autozone test it and they said it did 240 amp at 2000 rpm... but autozone also told me 2 of my old batteries were bad and there were fine when i had a mechanic test them lol. i don't really trust autozone people they really dont know what their doing. im going to take my car to a real alt guy next to where i live and see what his machines read.

ok, would there be a way to test to see if that might be the problem?

i thought that the alt might be the problem as well but it did the same thing with my stock one. and my voltage at idle is 14.1
