Voltage drop problem

[bs1991 0]

I have 2 fi SSD woofers in my 2001 Celica and the lights dim real bad every time the bass hits. I have a 2.4 farad capacitor, is that even worth putting on? or should I go for a new alternator or battery

Add another battery and do the Big 3. For more information on the Big 3 refer to the Technical section of the forum.

don't waste your money on a capacitor.. another battery will be alot more beneficial.. an alt will be even better..

put a voltmeter on your system so you can have an accurate idea as to how low your voltage is dropping..
