Monoblock amp wiring

Ok I got to thinking the other day about the way I wired my sub to my amp.

I am sure this has been discussed before. But I have been unable to locate the answer. If it has I appologize now.

The sub is an Alpine SWR-1222D and the amp is a MB Quart Discus 1000.1 Monoblock. The way I have it wired now is in parallel to 1Ohm with one set of wires to the amp on the outer positive and outer negative terminals. According to the manual that is for single svc sub. Is that way ok or should I physically wire each coil straight to the amp. As the amp automatically parallels both sets of terminals which would make this a 1Ohm load as well. Which way is better the way I have it or the second option?

okay so you have 1 d2 sub. right and if you wire the voice coils (terminals) in parellel (plus to + and minus to -) your ohm load will drop to 1ohm~!

Either way you won't notice a difference. Leave it the way you have it.

umm. Yes I know. That is what I said.

The way I have it wired now is in parallel to 1Ohm with one set of wires to the amp on the outer positive and outer negative terminals.

And yes the amp is 1Ohm stable.

Either way you won't notice a difference. Leave it the way you have it.

I didn't think it would make any difference at the sub. I just though I would ask.

But what about Amp efficiency? Would wiring the voice coils separately at the amp ( 2 x 2Ohm loads) be easier on the amp vs 1 x 1Ohm load since the amp it self parallels the terminals if all 4 is used?

No. Absolutely no difference. Once the signal is in the single positive and negative outputs before the split, it can't even tell how many splits to different terminals there are. You could put 1,000 splits with a 1,000 voice coil sub and it couldn't tell.

Ok thanks. I didn't know exactly how the internals worked. I don't have to worry about adding in a terminal cup or similar for a second set of wires now.
