i have one of those new rf amps..1500bd
the guy told me i didnt need the big3 and not sure about the battery..
i had originally purchase 0g wire...at this time i didnt really know muhc about wire so i didnt check it..
2 days later when i finally decided to check it..it was 4g wire..
when i took it back to him..he said i had payed for 4g wire..and that he was nice enough to put 2g in the front..not even a foot of wire lol..
i payed 250$ i thought it was a complete rip off,
