1 ZX2500 vs 2 AB xd1800's

[alxmlr789 10+ year member]

I bought 2 MX 12"s and need to power them at 2 ohm, i already have one xd1800 (1500 at 1 ohm) should i get another one and have each of them see a 1 ohm load or get a zx2500.1?

Which would power them better, and which one would be more efficiant?

What are the subs power rating?

1200-1500

In all honesty I would get like to amps that do an actual 2k@1ohm so you can have some overhand and not need to turn the gains up to get where you want, because that just causes clipping, I would say somthing like a single VFL200.1 or a 400.1

it needs to do that much power at 2 ohms..

Why not run the 200 or 400 @ 0.5 to better account for box rise?

the 200.1 is rated at 2000@2

exactly, like I said run it at 0.5 with box rise you will be getting a ton of power thats for sure...unless of course you have like 2+ohm box rise

How bad of a strain on my electrical will .5 ohm (runnin around 3500w) be?

The amp wont see 0.5 AFTER BOX RISE unless you have 0 box rise which is impossible!! In my box for a single 12 wired at 1ohm it rises t0 1.4 in 10 minutes 2.5 in 15 minutes...basically the heat in the box the coils get hot etc.....anyway the amp WIRED BEFORE BOX RISE ISNT GOING TO STRAIN YOUR ELECTRICAL, easy way to test is use a multimeter and see what the amp is seeing as a final ohm load while playing it...other ways to tell, but thats the easiest.

Last time a 200.1 before box rise will never see 0.5 ohm load!!

how bout a solid F2500..thats what i have right now
