I just bought a old school lanzar opti 50c amp but i need to know what is the postive and negtive for the speaker output and what one is for bridgeing?and what is the spec? what is the lowest ohm i can go

SOURCE: Lanzar Opti 50C

when there are burnt traces on board if its only a few you can bypass them with jumpers then all circuitry has to be checked and tested befor you go any further,can go into more detail just drop me a line randall 574-220-0162

SOURCE: 2 ohm speakers wont work on a lanzar max pro 4000 watt

The 2 ohm stable rating on the amp is PER channel meaning that you could effectively hook up a 2 ohm speaker or a 2 ohm load to each channel without the amp getting f"d up-butin bridged mode it will only be 4 ohm stable. to achieve a 4 ohm load with your sub the type x wire the coils in series that will get you at 4 ohms to run in bridged mono .But you will get the exact same amount of power if you wire each coil to one channel of the amp as bridged mono sees the sum of your 2 ohm channels combined-Hope that helps.

SOURCE: lanzar 800 watt amp protect mode stays on

protect mode usaully means that something has disrupted the power of feed lines to the subwoofer/speakers possibly fuse is blown in amp or amp is blown in which we hope not. see if you have a warrenty if blown and send back or bring it to where you purchased it from.

The 40 amp fuse is too small. 1000 watts = 12 volts @ 83 AMPS. Bigger power wire my friend. If you want to sell, let me know.
