i've got pg tantrum 250.2 running 1 tantrum 10 svc, and when bass hits my lights dimm. my alternator is 85A. There's nothing wrong with alternator coz the car is 3 months old (chevy lacetti). any advice appriciated
1. Check the gain, it's should not be more than 3/4 of the way up 2. double check on your alternator make sure it's 85amper. 250 rms max draw say 30amper, you should have more than enough for 250.2 IF you alternator is 85A.
DONT GET A CAPACITOR. all they do is act as resourvers of power. when the cap runs out of power then what will happen? well your cap will start to recharge. to recharge it has to draw the power from the alternator. while it is taking current from your alternator your amp will still need power so it can power the woofers. so while the cap is charging and drawing power off of your alt. , your amp will also be drawing power form your amp..
have you ever heard of upgrading the big 3 wires? i havent tried this out, but no one has told me thye done it and they didnt notice a differnce. what you do is replace the factory wires on your alternator, ground a 8ga wire off of your engine block and runa 8ga wire from your car battery directly to the chasis of the car.. supposely this allows current to flow though the car a lot beter and makes the electricle system more efficent. if this dosnt work buy a more power full alternator. a capacitor will b a wiast lof money
I just bought the car and don't have enough money for new alt. Could it be becouse at the point where ground wire is connected to chasis the paint isn't scraped off, so the amp has to draw more curent and then voltage drops???
You need to go larger than 8 guage for the "big three", at least 4 guage, but 2 or 1/0 would be best. A lot of factory alternator wires are 8 guage to start with. It will show a little improvement, but depends on the car. An alternator is usually what's needed in most current delivery problems.
