Subwoofer Wiring Diagrams, Two 4 ohm Dual Voice Coil (DVC) Speakers for running at a 1 ohm load on amp if stable

Subwoofer Wiring Diagrams, Two 2 ohm Dual Voice Coil (DVC) Speakers pair wired to 2 ohms if amp is only 2 ohm stable

No model number was given for your amplifier in question,.Please give model number of amp being used to get a better and more clear answer to your question..Thanks

That amp will not see 1200 watts @ 1 ohm with 60a worth of fuses. Those hds3s take 1200 w rms and much more on clean power. You may be able to power one sub in a larger enclosure.

Unfortunately, that was terrible info.

The gm-d9601 is accurately rated and uses 3x40A fuses.

It is a good match for a pair of HDS312's with d4's.

Yes, they can handle more power, but at 1200w rms and the possibility of a 2nd amp for speakers you wouldn't want anything much more powerful w/o an alternator upgrade.

Why?

I stand corrected, sonic has it listed as 30 x 2 fuses... looking at the actual amp spec sheet, n2 is correct.

Why?

For OP's sake...

We're talking about subs that need at least ~1000w rms to be worth buying. A (class D) mono is IMO clearly the best choice if for no other reason than efficiency (vs a/b multi-ch).

Also, at ~1000w they tend to be less expensive than a multi-ch.

Also, they tend to have processing specifically intended for subs. A muliti-ch will have a broad LPF and MAYBE an SSF.

Also - at ~1000w your choices for a multi-ch are going to be substantially limited, whereas ~1000w is probably about the sweet spot for class D mono's making the options abundant in any given price range.

So does it HAVE to be a mono? Not at all.

Is it going to be the best choice? For about any comparison? Yes.

I think I'm going cross-eyed reading the OPs' posts.
