A working alt, through ALL rev, normally, for a daily, is best. Just me.

Kyblack76 Posted March 22, 2017 Report Share Posted March 22, 2017 Again. Just me. But dropping to 9s ???? even if both alts are doing 80 amps, and you have a bit of reserve.... 9s ??? jesus. That board is rated at what ... 3k at 1 ohm, and your wired there. So your pulling maybe 150 amps at full tilt, on music.. hell, even 200 lets say...... (highly doubt). IF THAT, and your dropping to 9's?...... good hell. You have issues for sure. Big ones. You sure both alts are turning on? sounds like one isnt.......iif both alts are doing even a shitty 80 amps, and you have a few amp hours in whatever those batts do, dropping to 9's ? Jesus. Is the amp staying on even ? or does it shut off? EDIT- and,... seeing "i bought a ebay alt" makes me want to puke....... i know you wanna bang on a budget, but, everything ive ever seen, the OEM alt does better than a "ebay" alt. Everytime.

Blake21 Posted March 22, 2017 Author Report Share Posted March 22, 2017 I've moved both of my battery grounds now, do I have to have both of the 4 pin plugs on both alternators? Only one has that plugged up, I've got 1/0 from each alternator to the primary battery and then 1/0 to the second. Should I jump from 1st alternator to second and then to battery? With a volt meter both alts are putting out 13.5 volts. Yes if I play decaf music, low music it'll drop so bad the amp will cut off and all lights are basically off Link to comment Share on other sites More sharing options...

How are you turning the second alt on ? SMD SUPER SELLER The Burban Build Blazer Build sold Acura trunk build sold Link to comment Share on other sites More sharing options...

But do the alt upgrade first, see if that fixes it by itself. Maybe even upgrade ur batteries, cca is just cold cranking amps, important spec for cold weather areas, but not really a important spec for car audio. Check the AH (amp hours) rating, thats usually a decent indicator of power supplying abilities. Wire doesnt make voltage. If his alt does a max of 200 amp, wide open.... what would adding more wire do?

Blake21 Posted March 22, 2017 Author Report Share Posted March 22, 2017 Yes I only have one 4 pin plug connected to one alternator, I thought the second one would put out power without it Link to comment Share on other sites More sharing options...

Dude, you have to tell the alt to turn on, when, and how. You have to "tell" the alt to turn on....... your just spinning a pulley at the moment. The plug is there, for a reason.

Ahmed Johnson Posted March 22, 2017 Report Share Posted March 22, 2017 You need a plug on that alt. You won't get the other one to turn on. I think you can get it AutoZone. For sure ebay. I did it for my boy who just sold his shit but we had to run a wire to a fuse that only turned on when the key was turned and one to the battery.
