love tha bass
i have 1800 watts, the big 3 and a brand new battery up front, and a h.o. alt. iyou will still get dimming from playing it loud. you need an extra battery in the back to keep from working your main battery too much. put you a battery in the back so it can take the beating from your system. you will not be happy when you drain your main battery and have to be jumped off!! 200 amps will not cut it. call dominick irragi at 1-615-287-7991 or 1-615-594-8965. thats where i got mine at and he will tell you exactly what he can do for you and what you need.
