My s4 alt took a crap on me after fi days after i put in my system. but then again i got a RF 800a4 Bridged w/ 2 12's a RF 360a2 Runing 2 6X9's and a EQ to boot.



All my electrical problems went bye bye after i upgraded to an FD alt. And a MAC Power Pac Lead Acid Battery lol got to love 860 CCA 980 ca LOL
