Complicated Wiring for subs to mono amp

**trinibeta** · 01-04-2008, 05:17 PM

I have a Infinity 1211a mono amp here are some of the specs; 854 watts RMS x 1 at 4 ohms (1300 watts RMS x 1 at 2 ohms). I also have four (4) 12" Infinity 12.1 subs (SVC 1400 watts peak 75 - 350 watts RMS @ 4 ohms). I found this diagram to wire them up... http://www.crutchfieldadvisor.ca/lea...SVC_4-ohm_mono...
Now the issue...in the 1211a amp there are two sets of terminals to make it easier to connect multiple subwoofers. The terminals are connected internally in parallel...if you click on the last pic should be the right view you'll see what i mean... (http://www.crutchfield.com/App/Produ...08R1211A&g=120).

So how would i connect the subs to the amp to achieve the most power to get the most bass? or is that wiring diagram the only way...

You wiring options are:
1ohm (all in parallel)
4ohm (serries/parallel)
16ohm (all serries)

Now according to this forum your amp is 1ohm stable, just doesn't produce any extra power. In which case wire the +'s from each sub to the +'s of the amp and sub -'s to amp -'s.

I read somewhere else that someone tried it at 1 ohm said it was stable...i'll email infinity to double check...thanks alot...just to clarify your point i would be wiring two subs to one speaker terminal and the other two to the second speaker terminal...and since they are hooked up in parallel inside all running to the same connection it'll give a 1ohm load right?...thanks alot man like i said i'm going to call up infinity or email them or soemthing to double check with the 1ohm load being safe so i don't blow anything...
