I have a db drive Pd1200.1 amplifier and I need to get all its 1200 watts into one ohm. It has 2 positive and 2 negative terminals. I want to know how I can get all its power into a dual 2 ohm sub. Is there a way I can wire it to get it all out or is this impossible? I need to get it all out because the sub is a 12" Sx. 1000 wrms.
Thnx. |

wire it in parallel

yes I know if I wire it in parallel I'll get a 1 ohm load. What I don't know is in which two terminals should I put the wire that comes from the speaker. The amp says that I cannot put lower than 2 ohms on one pair of terminals. Can I put one positive voice coil wired with one Positive terminal, then 1 negative voice coil with one negative terminal, and do the same with the other two but with the remaining terminals? Or what could happen if I do this? |

so ur amp has 2 positive and 2 negative terminals??, if so it is still a mono amp, they put 2 on there to make wiring two subs easy, but if ur amp is not 1 ohm stable u cant do it, btw register |

I think it is 1 ohm stable. I used to have two 10" L7's Dual 4 ohm wired in parallel. The amp says it is wired in parallel internally. I don't know if this helps.

Blondechic, from what your manual is saying, it looks like your amp is 2ohm stable, not 1ohm.
Check your manual carefully. Somewhere in there, it will tell you exactly what the minimum ohm requirement is.
If you want to test your amp, then take each VC and connect the pos and neg to one terminal and the 2nd VC to the other terminal. If your amp is really 1 ohm stable, then it will power up without going into protection mode. |
