I am upgrading my stereo system to where I will be gettingabout 1500 rms total. I have a 1998 avenger V6 automatic. Do you think i will need to upgrade the alt to handle this? And if so, can you provide me with a link of where I can get one online?

Another option would be maybe just upgrading battery to this:

This calculator will tell you the required alternator rating for your vehicle at peak usage. It may not be possible to meet these specs with a single alternator or even necessary to. Many other factors come into play such as driving and listening styles. It will however give you the ideal answer and a good indication of your present alternator's ability to supply your system. It takes into account the current draw of the OEM electrical accessories, the current draw from your amplifiers at peak draw and the current draw from any other electrical accessories (neon, fans, strobes...) in your vehicle.

So based on 300 amps, i take itI need a pretty big alt? I was hoping I could slide with just a battery upgrade.

 

That is WORST CASE ...
I'm running 2250 watts on a 180amp alternator ...
Upgrade the big 3 and an Optima battery

 

Ok thanks. I might just upgrade the batt for now and see what happens then. My equipment is in the mail but I am just trying to think ahead. i could also keep the gains down a bit in the mean time.

You know anything about these Kinetic batts? On different forums I have read they can outperform yellow and red tops

 

kinetic stinger and odessey all make real good batteries

 

Yea man i will say upgraden my batt. was the best thing i did.. My lights and engine would die down so bad i thought the car was gunna die lol. Just got a new red top 34/75 and wow after a day of driving on the batt everything is working so nicely with out any dimming and i still needa finsh the big 3..

red top was worth it

How many total rms watts are you running in your system?
