SOURCE: how 2 bridge tha opti drive 1222d 12inch subs 2 the opti 600x2hc

You can check Both Crutchfield's learning center on subwoofer wiring diagrams and www.the12volt.com with their wiring diagrams. The crutchfield setup will be more informative for this type of problem. Just go one of the + to one of the - on each sub then wire the other plus's together between the subs as well as the minuses like between the subs and use the open plus and minus that u didn't just bridge. Then there should be just 2 wires a plus and a minus to the amp. Then follow the amp bridge wiring which should be found right above the speaker terminals it will be left plus to right minus or the other way around

SOURCE: i have an old lanzar

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. Box size will be 11 inches x 11 inches x 11 inches. Hope this helps

My Lanzar Optidrive plus has a green light and a red light. I assume this is a sign of safe mode. normally it is just green. How can i get it back to normal and in working order. I already tested other...


your output of the amplifier have been distorted. I suggest you take this to a reputable service technician that has experience with lanzar OptiDrive old school Rockford Fosgate or Orion. These technicians are hard to come by nowadays but they definitely are worth the money that they charge. I happen to be one of those such technicians.

I have a Lanzar Vibe 235 amp. the green power light is not coming on, but the red "protect" light is. how do i solve this problem??


Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty. Time to purchase an old school Lanzar Opti Drive. Any of them. The 50 will kill some 12" subs .A thumbs up would be greatly appreciated if this answer is helpful to you. lanzar-vibe-235-amp-green-power-shonxoarcym4awy4zl1imx4o-2-0.jpg Lanzar
