Is a Skar actually... "good"?!(OPINION WARNING)(SKAR HATERS BEWARE)

Just kidding, I don't care about brandism... UNLESS ITS BOSE!(ALSO A JOKE, chill) A contrast between my DSLR camera vs a phone camera. I know some viewers thought my stereo wasn't very loud because of the DSLR, maybe this will change their minds. My biggest hold back atm is voltage... running 2 lead acid batteries is not enough. Looking into alternators now that I've had some questions on the subject answered. Thanks @stuskustomshop for the advice.
