20 Most Recent Lanzar OPTI1532D Car Subwoofer Questions & Answers

Do you have just one???? If so and your amp can handle a 1 ohm load, hook one voice coil to the other (positive to positive, neg to neg) then bridge it to the amp...If not you will have to take the positive of one voice coil and the negative of the other and bridge it to your amp....The other hot of one voice coil and neg of the other needs hooked together (jumperwire). That will give you a 4 ohm load.

Based solely on spec sheet information the Lanzars can handle 1300 watts RMS and the KX1200 is rated at 300x1 @ 4 ohms, 600x1 @ 2 ohms, & 1200x1 @ 1 ohm. Even with a 1 ohm load you will still only be providing 600 watts to each sub. While the kicker will provide more power at 14+ volts, no car creates more than 12-13 volts via its alternator. A car battery only provides 12.6 volts. So you will be loking at 1200 watts from 1 channel as a best case scenario.

Additionally, with your 2 subs, they will need to both be Dual 4 ohm voice coils in order to net a 1 ohm final load. Each voice coil will need to be wired in parallel and then each speaker needs to be wired in parallel.

Yes you Can. run them bridged parallel. meaning on the amp where the speaker wires attach there should be labeled with a "+" and "-" with a line drawn to show which terminals to hook the bridge wires up to. bridging takes power from both sides of the amp and puts it into one strong signal on half the wires. from there run your "+" wire to the first "+" on your first speaker. run your second wire from "+" on spk 1 to "+" on spk 2. repeat process from "-" on amp to "-" on first speaker and then to second speaker. __ ' a'"+"________"+"_______+ Good luck, may the force
/ ' 'm'"-" spk spk be with you!
bridged \ '__ ' '"-" ________"-"_______"-"

this will get you the most sound from the amp. if using 4 ohms speakere you will be running a 2 ohm load bridged.

Depends entirely on the output impedance of the amplifier and of course if it matches your loudspeakers.

Your 8ohm channel is fried why happened was you ran 2 12s in an 8ohm load and turned it down to 2ohms the speakers was pulling all the power and that made it over heat and when it over heated it fried you're amp. It ain't no good you can't fix that

Bad connection inside either on a connection or on the PCB itself.

When an amplifier causes trouble or otherwise stops working, it is necessary to eliminate external possibilities such as a short circuited output. If nothing external is causing the problem, unless you have a good friend who is an electronics engineer, it will be a repair shop task...

Check your fuses. Check to see if any of the wires are loose. Could be a blown fuse or loose wire. Possibly the following link might be of interest: https://www.youtube.com/watch?v=xMbsieEj0UM

have diagram of any sort?
