Hey i have ordered my amp its a kicker 850 amp 4channel. Will this amp be able to push four 8s two 6s and two horns? (all speakers are selenium). If so could it push 2 more horns or 2 more 6s or all 12 them(four 8s four 6s four horns)? And will it drain my battery? Thanks 4da help

Yes it will and no it won't. Just make sure your ohm load is good. Don't know why you would tho. My boy runs 2 850.4s for just a pair of horns, pair of midranges and pair of midbasses. It's not about the amount of speakers you have.
