Hooking up two identical mono blocks into a single dual coil subwoofer

The 2 amps are not strappable? What amps are they exactly?

Honestly? I have no idea. JBL GTR-1001. 1000W RMS at 2 ohm.

yes if you gain match you can use 2 amps but i wld suggest you take it to a shop so they can match the wattage outputs cause even tho the amps are rated the same the wattage will be different from amp to amp 

It is impossible to truly match two outputs, and being off by a small margin doesnt effect anything. If you take it to a shop, they are just going to do the same thing we are telling him to do. Set a proper gain level on amp 1, measure amp 1 ACV, set gain of amp 2 to make ACV of amp 2 match amp 1 ACV.

Those aren't strappable. Your best bet is to gain match them using a multimeter.

Just gonna throw this out there but if you are only running one sub gain matching is not a requirement and the two coils receiving different amounts of power would do absolutely no damage of any kind assuming its clean power and neither one is not being over driven.

Gain matching is important when running multiple drivers in a shared enclosure though.

Long story short, make sure gains are set properly and let her rip.

I seen 4 amps ran to the same sub back in the day. Audiobaghn quadcoil sub with a mono lock per coil. Dude was competing and had 2 15” and 8 Mono blocks so yes it can be done. This was of course back in the day “early 90’s” when high wattage amps where super  expensive and not as readily avalable as today. You young guys got it made with all these $1000 dollar 5k’s!

Used to be about a dollar a watt, now if you arent getting 5 watts per dollar or more, it aint a good deal. (Generally speaking)

You don't need to gain match with a single sub. The only time you'd need to gain match is if you couldn't hook up every amp to every sub. Set the gains with a DD1 or Oscope to get the maximum clean power out of each amp as possible. Gain matching (reducing the higher powered amp to match the lower powered amp) will only mean lower power to your sub.

You would need to phase match, but it looks like the amp has a switch instead of a knob so luckily for you that's taken care of.
