Have you used a volt meter to test the alternator output? A volt meter isn't very expensive, maybe $25 or so. You definitely should clean the terminals, they need to be clean for proper charging system operation.

 

im a try 2 get it 2 day....thanx cuxz u always helpin with info...btw im a get a pic wit my system 2 day....

 

After you clean the terminals spray some protectant over them to prevent corrosion in the future. Any mechanic will probably have the spray, so next time you bring your car in for an alignment or something, ask him to do it.

 

Your spelling sucks & turn off the freaking caps lock.

 

Your problem is the subs in your trunk, Added weight in the trunk FTL

Since you have a heavy system in the car, you should get a 160 amp alternator, I have one but I don't have a system.

 

An upgraded alternator is the LAST thing you need to do to help with a system. Sorry, but your suggestion is overkill, and more than likely, not necessary.

 

Actually one of the best things to use on the battery terminals to prevent corrosion is Vaseline. You don't need to use too much.

 

u wouldnt believe this.....i went under the hood and double checked all my alternator wires/ground....then i find the problem.>the clip that clips onto the alternator had the actual part that locks the clip broke off...i guess when i changed alternator before....so i went and found the clip from my other alternator it had 1 when i got it ...so i matched it up and everything is 100%...thanx yall...i found this site off b20vtec.com....
