adding batteries, isn't just about adding batteries... some must be properly mounted outside because of exhaust with the acid.. make sure you buy the right batteries if your gonna put it on the inside of the vehicle, and wiring is key. Must be good.

man i did both alternator and 2nd battery and never have issues unless I go full tilt within a few minutes of starting.

Hello.

I am currently rocking around 3,300 Watts in my car stereo.

I have a 2011 Hyundai Accent.

I have 2 batteries in the vehicle, both are aftrmarket LARGE car batteries.

Under Hood:


In Trunk:


My STOCK alternator is 95 Amp @ max load and like 5X @ Idle.
@ 2,000 RPMS most systems will be okay, @ idle... It gets annoying.

I found a person, Michael Singer who makes an alternator for my vehicle.
He wants 412$ shipped to my door with a lifetime warranty.
The new alternator adds 200 Amp @ Max load and 110 AMP @ idle... That is 15 more Amps @ idle than my current Alternator gets @ max...
I will have no problems after I add the new alternator.

If it bothers you that much, get a new alternator.
I have 400$ in batteries and another 400$ is going to a good alternator.

Just my .2 cents
