Subs causing throttle issues

I haven't posted here in a very long time but I need some help.

I've recently installed an aftermarket stereo and subs in my car. When the volume is turned up fairly loud, it causes a kind of modulation in the throttle almost as if you were just giving it a quick blip, this makes me very nervous. Can anyone help?


My mod list finally got too long to post in my signature. I must be doing something right

Your pulling more power then your alternator can produce so it tries to pull more. That's why people with big setups have to rev the engine or set up separate batteries.

Exactly what it is. Had it happen in my old explorer when I had a pretty large setup. Best bet is to set up a battery in the trunk to power the subs, so you're not pulling all the power from the rest of the car.

you should try some really good caps. I had the same prob for my import cars and the caps solved the issue.
