im running these subs 2 my 2000 watt performance tecknique do i wire them +2+ -2- each sub to its channel ch.1 + - ch.2 + - or do i go all + and - bridged 2 the amp please help i also had a 80 fuse and i took it out and but a 40 fuse is that bad .also how much should my gain be turned up on my amp AW1200EU 12" 700 watt subwoofer 120 oz.

The easiest way to wire your subs to a 2 channel amp is as mentioned first in your post.
Channel 1 +++++++++++ Sub A, both + lines
Channel 1 ------------------ Sub A, both - lines
Channel 2 +++++++++++ Sub B, both + lines
Channel 2 ------------------ Sub B, both - lines
Both channels will see a net 2 ohm load and safe for the amp. This is easier than bridging and same power to each sub.
A 40 A fuse is OK as long as you use #8 gage wire or larger. That value fuse will allow ~ 600 watts power draw from your amplifier before it blows. I this case, the gain settings will be just below the 40 A fuse limits. If you exceed that current flow, that fuse will blow. Good idea to have a few spares on hand.
What are the fuse values in this 2000 GRIN watt amp?

Depends upon if lightning strikes the chassis.....woops, forgot my dookie

thanks 4 the diagram realy helped .so if i had a 80 amp fuse will i get more from the amp because it originaly came with a 80 amp fuse

Yes, ran a few quick calculations and with an 80A fuse, this amp will delivery about 700 watts RMS total. (350 RMS per sub @ 2 ohms per channel)
14.4 volts x 80A = 1152 watts consumed
1152 x 0.6 (eff. factor) = 691 watts RMS
If using a 40A fuse, your power the amp can draw will be cut by 50%. The output is now just under 350 watts RMS. (175 RMS per sub)

i whant to say thanks for everyones help and patience .its realy appreciated im having problems with my 2000 watt ibmn-782 performance teknique amp it keeps on shutting down on me im running my adiobahns aw12000eu audiobahns the way ther connect is sub a positive to ngative then out to the amp to its match pos.and neg. same applys to sub bnow on the outer part of the box i have positves from sub a & b to the bridged pos. on the amp and the same for the neg.is this wrong please help

Am trying to make sense of your last thread and think you may have wired these subs improperly for Bridge Mode Mono on this amp. (Too low of a resistive load will shut the amp down) Below 4 ohms when Bridged.
Here is the wiring plan you will use: (Series/Parallel =4 ohms)
