help me please ... i want to add another sub ...
I have illustrated my question in an attached jpeg...
but heres i go to try and explain it ...
I have 2 subs rigged up, and bridged together and i want to ad another of the exact same sub, do i just hook it into the other 2 i have connected already? or do i have to do something funky with the wiring?
please help, im new to this.

The answer is NO!
The Alpine MRV-T757 is only 4 ohm stable bridged. It might work for now, but in the long haul that could very easily deteriorate the internals of amp if it doesn't go into protect mode.
Your options right now are go back to just 2 subs, or wire them for a 6 ohm load:
Each of the subs dual coils are wired parallell to get a 2 ohm load - then series the three 2 ohm loads to get 6 ohms . . . based on the amps specs, I would guess that a 6 ohm load would get about 225WRMS from the amp - so each of the three subs would get 75 WRMS. Or back to just two subs and you'll work with 300WRMS and each sub will get 150WRMS.
If you need any hands on help, I'm just 20 minutes south of you and I can lend a hand.
