This is in the wrong section for questions about competition amplifiers for dbdrag. But the cheapest amps for Street B this year that will be close to the big expensive amps are-
Sundown 3000d's
New version Hifonics XXV cyclops's
Crunch GP3000D-Pro (best bang for buck) $500 //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
Digital designs M3's
All these are aprox between 500 to 800 each. Find them used, then even better.
And your best battery to choose will be Northstat NSB g3100 , Hawker 2150.
Good luck and welcome to Street class.
