audiofanaticz Posted February 8, 2008 Report Share Posted February 8, 2008 i have a 02 sierra with a vortec 4.8 my question is does anybody know how many amps is my alternator ? depends on your truck. If its a sierra 1500 4.8 2 or 4 wheel drive it has a 105 amp alternator stock. Their are also 130 and 140 amp alternators that should be avaibile to you from autozone or any other car parts store, but you may need to use your stock pully from the smaller alternator. And you should easily be able to have a high output 300amp alternator made for your truck Hope that helped a bit. Link to comment Share on other sites More sharing options...

I would really try and suggest moving the hc1800 closer to the amp for best results possible, and also do the big 3 when you get time to, it will also increase performance. In simple terms: The amp is going to try and draw the needed power from the closest point possible, if you have the battery within 2 feet or so from the amp, its going to use that battery to power the amp, and any additional power it needs it will take from the next closest thing with the least resistance. Depending on what amp you are using the hc1800 should be good enough to power the amp on its own and the alternator will keep the batteries charged.

Put the hc1800 as close as you can, and do the big 3. That should solve your problem. Link to comment Share on other sites More sharing options...
