Amp and sub matching

[ultraSoundWave]

I am inquiring about the compatibility of my amplifier, which is rated for 2000 watts RMS at half ohms, with two Dual Voice Coil (DVC) 12-inch 2-ohm subs, each having a power handling capacity of 1200 RMS. I am seeking your expert advice to determine if this combination would be optimal or if it would be advisable to consider subs with a lower RMS rating, around 750 each, to achieve a better match.

Your guidance on this matter would be greatly appreciated.

Max power handling is one thing, your needs/use case perhaps another. What amp is it? What subs?

Your sub will give 1 Ohm load in parallel. Your amp will possibly do about 1 kW into that load. RMS wise that should be okay.

Run some sims on the woofer and enclosure to see if that works for you.

And what size room?

I thought it would be half ohm in parallel. two 2 ohms each inn parallel is 1 and then the two 1s are combined to half. At least that's what I understood, thanks

Yes, if you have two subs, they would go down to half an ohm if all is in parallel.

I’m pretty sure the space involved is a car

Make sure to use thick cabling. With such low impedances, the wire will be a significant factor. But personally I would not trust a sub without a full complement of TS parameters..

its an suv, and yes certainly using the big cables. 0 awg. thanks

Ah, car setup, makes a bit more sense now. 2000.05 fwiw https://www.mmatsproaudio.com/site/product/m2000-05/

Right that's the one, I will include the links next time with any questions. sorry
