Cut your gain back on the amp. It sounds like they are set too high. Check your install instructions on how to set your gain. If you have a 4 or 5 volt output head unit your will not be at half way. Im running a JL Audio 500 /1 on a skar wwv10 dvc in a ported box. My gain is set about half way & its plenty loud.I have a Alpine 9887 headunit 5 volt output on my RCAsI can take a volt meter & set my speaker output at 45amps & my gain in perfect.

I USETD TO HAVE AN OLD 600 WATT ZUES,THAT MONSTER USE TO BLOW ANYTHING .I WOULD LOOK UP HI-PHONICS IF I WAS YOU.OR FOSGATE. RATING PLEASE.

SOURCE: How to wire 2 ohm 2 12ich alpine type r's to box terminals?
Dual 4 ohm subwoofers can only be wired @ 1 ohm, 4 ohm or 8 ohm.
2 ohm mono load is not possible.
You will need to use (1) subwoofer to get the 1000W out of the amp.
Wire both positives on one sub to + on amplifier and both - on the same sub to - on amplifier to give the amplifier a 2 Ohm load.
Add a second amplifier, or buy an amplifier that is 1 ohm mono stable.
You can wire both to the amplifier at 4 ohms 600W, but they will share the power and only see 300W ea.

500W x 1 @ 2ohm
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.
Still going??
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.
Retry -
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.

SOURCE: what is the best way to wire two alpine SWR 1222D
First off excellent choice on audio equipment, i guarantee you won't be disappointed. So your subs are dual coil 2 ohms. So wire each individual sub in series. If you don't know what this means i'll explain. On each sub there are 2 sets of wire terminals. Connect a wire from the one set's - to the other set's +. Do this on both subs and you will have the coils wired in series making each sub 4ohms. Now to hook the subs together you'll need to wire them in parallel. Now since you have your coils in series, on each sub you have one + terminal and one - terminal left. So run a wire from the + terminal remaining on each sub, and run them to your amp. Splice the ends of the two wires together and plug them into the + speaker output of the amp. Connect the two negatives in the same way and plug them into the - port on the amp. You will now have your amp running at its desired 2ohms. When wiring this disconnect the fuse on your amp power wire to avoid short problems. And if you get confused at all, and aren't sure what to do, ask again don't guess, if its done wrong you could severely damage your equipment. Hope this helped, enjoy the bass...

Hi jimmyjames,
How do you have the wires hooked from the sony reciever to the inputs on the mtx?
Sounds like your Remote wire is way too big. it should be 14 guage. It only sends a low voltage low amp signal.
Another thing that could be messing up the sounds is the routing of the wires. you should have the power supply wires separate from the Audiop signal wiring. Power should run down the Driver side and Audio down the passenger side.
When you answer I may be able to tell you more.
