Open the sub box and see what it looks like before you go purchasing stuff with no problem for certain. You may have had wires touch and they will smoke. Also try connecting a different speaker to the amp and see if it works. this lets you know if the amp/speaker is working or not

I recon you have blown a voice coil.
my guess you were running two dual 4ohm wired in parallel/parallel showing a single 1ohms load to the Amp.
When mine went pop, (i had Dual Voice Coils) it sounded a bit like a steam train. Anyways, if both of your speakers are in one box then the whole box will sound rubbish.
1st you need to determine which Subwoofer is at fault, -try removing one from the Box and connecting it directly at very low volume. the other onw car be tested while its still in the box in the same way.
Do not try and thump them while the box is open, keep the volume just loud enough to hear the "Odd" sound..
Better still use a 9v battery or similar (even a fresh 1.5v should do something), and connect to ONE voice coil at a time, the cone will move forward or backward depending on which way you connect the battery, the voice coil that doesn't cause movement is faulty.
or use a continuity meter.
2nd Either replace the blown sub, or Rewind the voice coil.
but my advice would be to replace the blown speaker.........

Kicker 12L5 blew from a kicker zx750.1


MY BEST GUESS FROM WHAT YOU HAVE SAID IS THAT THE BOX WAS TO SMALL. BUT YOU ARE OVERPOWERING THE SUB RUNNING IT AT 2 OHMS ON A 750 WATT AMP WITH A SUB THAT IS ONLY RATED FOR 600. NO MATTER HOW FAR YOU TURN YOUR SETTINGS DOWN, YOUR STILL PUSHING TO MUCH POWER FOR THE SUB TO HANDLE. IT IS ONLY RATED 600 WATTS FOR A REASON. ESPECIALLY IF YOU LISTEN TO MUSIC THAT HAS A REAL LOW END AND THEN A HARD HIT. REMEMBER A HARD HIT WILL SPIKE YOUR AMPS OUTPUT THEREFORE PUSHING MORE WATTAGE TO THE SUB.

What size box should i build fro two pioneer 12inch speakers 1200watts each


For optimal performance there is really only one size for the box .Firstly, you get two different types of subwoofers, an open air, or closed air sub. If it is an open air sub ( hole with mesh in the center of the magnet) no ports are required, and the box should be sealed on the inside with silicone sealant. If it is a closed air sub ( no hole in the magnet) you need a 50mm port about 120mm long. If it is a 12 inch speaker, the box size will be 13 inches x 13 inches x 13 inches.

Is my 1200 pioneer amp a good match for my 1200 watt pioneer sub


this is too close, your speaker wattage is alway's higher than your amplifier's wattage alway's to be safe because the hard pounding will make the speaker work harder, and this will cause your speaker burn out easily, though you can adjust your amplifier anyway's

Wireing diagrams


Hello stingerman20,

Your Directed D2400 amp is CEA2006 Compliant. It is stable at 1ohm and will produce 1,200 watts into that load. So you want your subs wired as close to 1 ohm as possible.

The only 3500 watt Pioneer Premier series subs I could find were the models number TS-W3002D2 and TS-W3002D4 with dual 2ohm and dual 4ohm voice coils respectively. The wiring options for the D2's result in 0.5ohm (too low), 2 ohms, and 8ohms. Your best option would be the 2ohm configuration which would be voice coils in series and subs in parallel. Options for the D4's result in a 1ohm load and a 4ohm load. Your best option would be the 1ohm configuration which would be voice coils and subs parallel.

To see the wiring options, try Rockford-Fosgate's "wiring wizard".
Select 2 woofers and the appropriate voice coil impedance and quantity and click "search". It'll bring up all of the possible wiring configurations along with the final impedance load.

Hope this helps.
