I am setting it up for a minor SPL competition. I have had it set up before, but now I am in the process of fabricating my midgate for the ample airspace that I need. I have 2 T112D4s powered by a Power Acoustik 3000w (OVN1-3000D) monoblock amp. I have both T1s voice coils jumpered for 4ohm, and I wire them from the amp in series. The output of the monoblock amp is + + - -, thus I have both of the positive outputs connected to the both of the postive connectors on the voice coils, and the same for the negative outputs on the negative voice coil connectors. I plan to have it tuned the same at 37Hz. Out both of the outputs still measure at 4ohm. The question I'm asking is, is this right? Or is there a better suggestion? //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif
