Hey well your gonna need to give more info. is the sub dual 2ohm dual 4ohm. if you have a dual 2 ohm you wire one + to one- (like a jumper wire)and then your other +.- go to your amp as 4ohms, if you have a dual 4ohm model and your amp can handel 2ohm stereo then wire your +to+ to +on the amp and the same for your -. it will bring a 4ohms to 2 ohms by connecting pos. to pos. and neg.to neg. then to your amp.
The amplifier is only stable to 2 ohms.
Assuming the cubs are dual 4 ohm voicecoils - a 2 ohm load with 2 subs is not possible.
You can only wire up 1 dual 4 ohm voicecoil sub (both positives to amp... and both negatives to amp) to get a 2 ohm mono load.

How did you "switch the sub from 2ohms to 4 ohms"?
If you have the swr-1222d as listed, your only options are wiring 1 or 4 ohm, as it is a dual 2 ohm voicecoil.
If it was wired @ 1 ohm - you may have already done the damage to your amplifier - as it is not rated @ 1ohm mono.
There are 3 reasons the amplifier will go into protect mode while playing... Thermal - overheating due to too low impedence. Ground Loop/Short Circuit - Blown voicecoil, bad amplifier ground, tinsel slap, etc. Overload - Impedence not within specs.
Disconnect every wire (including RCAs) from the amplifier. Reconnect only power and ground - make a short wire to loop from power terminal to remote terminal.
If the amplifier stays on without turning off - remove the jumper, add the remote wire, and try again.
If it turns off - the problem is internal and needs repair.
Still on? plug in 1 rca, and re-try.... then the other.
Now use an Ohm Meter - or Digital multimeter set to ohms 20, and check both voicecoils. They should read 2ohms +/- .5ohm.
If they are OK, wire up the 4ohm load (series the voicecoils) and turn the gain on the amplifier to 1/2.
If the amplifier continues to fail at higher volumes - the thermal protection relay has become weakened because of your improper wiring, and will need to be repaired to solve your issue.

Are these Dual Voicecoil Subwoofers? Are there 4 terminals on each sub for wires?
If they are Dual 4 ohm voicecoil subwoofers
- connect both + on subwoofer 1
- connect both - on subwoofer 2
- connect both + on subwoofer 2
- connect both - on subwoofer 1
This will give you a 2 ohm STEREO load.
To get a 1 ohm MONO load...
now connect only one of the + on EACH sub to the + on the amplifier.
and the - on EACH sub to the - on the amplifier.
You now have a 1 ohm mono load.
If your speakers are 4ohm single voicecoils (one pair of terminals) the lowest impedence possible is 2 ohms.
This is wired in the same fashion. Both + on the subwoofers to the + on the amp, and both - on the subwoofers to the - on the amp.

what impedence are the voicecoils?
Dual 4 - Dual 2 - Dual 1 ??
Orion SX / GS / HCCA amp Wiring guide:
Orange = Right Positive Black/ Orange = Right Negative Yellow = Left Positive Black/ Yellow = Left Negative Blue = 1+1
Bridging of SX or HCCA Amps: 1. Use the Orange wire for Positive. 2 Use the Black/ Yellow wire for Negative 3. Push "in" the Mono Button
That amplifier is only 4ohm mono stable - so assuming the subs are dual 4 ohm voicecoils...
First wire both in Parallel Independently So each subwoofer is now a 2 ohm load. (combine + and + - and- on both subwoofers)
Now Take a positive on one voicecoil of sub #1 and attach to amplifier+(orange)
Take a - on that same subwoofer and attach it to a + on the OTHER subwoofer.
Finally, take a - from the second woofer to the amplifier -(black/yellow)
Now you have a 4 ohm load on your bridged channels.

The best you can do is connect the dual 2 ohm voice coils of each respective sub in series (4 ohms total per sub) and then connect each sub to one channel of the amp. This will give each sub 1000W, which is the rated maximum from Kicker.
