Brandenperry4444 Posted June 23, 2021 Report Share Posted June 23, 2021 My name is Branden, I have a 99 honda accord 4cyl that I have been having trouble with ever since I put the high output alt on. I've had this Amp in three different cars on stock alternators and never had any problems, if I have my volume too loud I can get the belt to smoke... Also at idle the rpms drop like crazy when it's only about half way up. I'm shipping out the alternator today but I really just need some help. I have a few years of experience with car audio and have never seen anything like this, here's my setup. Js alternators 250a alt 0/1 ofc all thru 1 battery under hood 1 in trunk both lead acid Twisted sounds 3.5k Directed audio 600 /4 1 12" fi q neo New 250a fuses If you can help me out please do!

Kevin JT Posted June 23, 2021 Report Share Posted June 23, 2021 I had a lot of issues with belts on my 97 Camry when I had it. I had a CES 320amp alt, but no matter how hard I tried, I couldn't seem to get the belt tight enough. The factory mount and tensioner had broken off. I also had issues with the RPMs, because I didn’t have enough engine power. Not sure if any of this applies to yours though. Link to comment Share on other sites More sharing options...
1point21gigawatts Posted June 23, 2021 Report Share Posted June 23, 2021 Come to think about it, you need a tighter belt or switch that small JS alternator pulley and switch it which your stock alternators stock pulley. “How can we help you?” “And don’t forget to tell them that the customer isn’t always right.” Link to comment Share on other sites More sharing options...
Brandenperry4444 Posted June 23, 2021 Author Report Share Posted June 23, 2021 I asked about a larger pully because that was my train of thought as well, bigger pully would in turn make it easier to spin right? Js said that it would hurt the alt because rpms aren't right, there are guys with my exact same car and a 320a with zero problems. I've recently put the stock 90a alt on but it just can't keep up with everything. All help is welcome! Link to comment Share on other sites More sharing options...

It helps a bunch because it seems like your having the same problem I am, was it a 4 cylinder engine? Did you ever get it to a sweet spot where it wouldn't drop rpms?

Goomz Posted June 23, 2021 Report Share Posted June 23, 2021 1/2"-1" shorter belt is required because they use smaller diameter pulley's. Best bet bring it to a mechanic so they can order a few and try them out, if they dont have one in stock. It sounds like an easier option for you. instagram.com/installsbypat Link to comment Share on other sites More sharing options...

1point21gigawatts Posted June 24, 2021 Report Share Posted June 24, 2021 And if you do have the needed size smaller belt, then the problem is possibly the alternator pulley is too small and causing issues and needs to be replaced with a regular size pulley and use your oem size belt instead. “How can we help you?” “And don’t forget to tell them that the customer isn’t always right.” Link to comment Share on other sites More sharing options...

I ended up just giving the car away after putting the factory alt back in. Link to comment Share on other sites More sharing options...
