need expert advice on sub/amp setup

[str8ceez]

Hello all I'm just looking for some helpful advice on my setup I have 3 12" pioneer tw302r 4 ohm subs and a hitron hra-2900b 1400 watt amp 2-channel The triple 12 box that I have has only 1 termina n the back, so I have it wired to 1 channel I have little knowledge on proper speaker wiring, and don't really understand how you get the different ohm levels. I do know that my subs are wired in parallel all 3- to the terminal and all 3 + to the terminal.- to the terminal and all 3 + to the terminal. Now when I turn up my radio it cuts out. And the subs start hitting a little irratically. subs start hitting a little irratically. How do I correct that problem and how do I make my setup hit the hardest it could. Wich is what I reall want it to do Any help will be appreciated thanks in advance

its an svc, and your only options are 1.3 ohms like youre running now (and that amp cant take it, hence the crapping out and sounding weird) or 12 ohms where it will not cut out or sound weird, but the volume would be decreased drastically

return it to whatever walmart or fleamarket you got it from, tell us your budget, and we'll help you out
