If you have the Alpine SWR-1222D, that's a dual 2 OHM Sub. So, the way you have it hooked up to the amp ,it's 1 Ohm, and unless your amp can safely operate at 1 OHM, you are better off connecting the voice coils in series so the amp will see 4 OHMS. The link below will show how the connections are made to the amp. Look at example # 1.

Hope this helps!

I have the 3311 manual. Do you still need it?

According to an Alpine owner's manual, for that type of amp, you should be able to remove power from the amp, then reconnect power to reset the error. If it doesn't reset, either there is another short in the wiring or the amp has permanent damage and needs repair.

check for proper ground also main12v and ignition

Hi SPDGOD,

 

Could not find exact, but close manual.  It is the MRP-M450 mono block amp from alpine.
