Hello people on this fourm good morning. Ok so i have installed a car subwoofer system into my vtrtubro. Its pushing around 1500 rms on stock electricals. When you increase the volume high the bass seems to sound less loud and also the xenon lights start to dim as the bass hits. Now i am aware about upgrading the alternator, big 3 etc, deep cycle battery, but do you think a power cap would do the trick because according to this
car audio website i came across it mentions in the article that it will help it slighly. You can also get different sizes ones, which one is the best.
