Hello people!
I got myself pair of series 1 Lanzar amps, made back in the day by mr. Zed. These have been sitting for some time in my closet and now I'm ready to give them a good use with old oldskool setup.
Problem is that, for god's sake, I cannot figure out which wire color goes to which channel and which is plus/minus.
Lanzar 240 is 4 channel, Lanzar 160 is two channel. They maybe resemble some old hifonics amps?
Anyone here that might be familiar with these motherboards? Thanks for the help!

The small amp tells you all that you need.
If you're still unsure, power the amp up. Drive signal into one channel at a time (switch amp off when moving RCA) and mark the board so you can remember which channel is which.

Just one question about connecting RCA - Would it be possible to connect just one RCA at the time and accidentally bridge the amp and still get the output from it even if I connected two different channels to the speaker?
Yes but it wouldn't be any different in output than connecting one channel normally.
It would, however, be very different to the amplifier. Having the amp bridged across two channels with only one channel with signal (the other (silent) channel, acting as a ground), would cause the channel with no signal to heat up very quickly and could cause it to fail.
Pick any of the 'dead' speaker wires (yellow or green) and connect one speaker wire to that wire. Leave it there to check all others for signal as you drive signal into each channel, one at a time.

Info for all people that might be using these old Zed made amps. As far as I know there are also old Volcano amps with the same architecture and maybe few more.
On the 4 channel Lanzar wires are NOT matched "color/color with bck stripe" for each channel.
Instead all white and all brown wires are '+' signals for speakers. Yellow and green ones are minuses. That being said, you can connect any '+' wire to any '-' wire and it would work. It's obvious that all minuses are interconnected.
I bridged it by connecting white with green and brown with yellow. It's now pushing two oldskool Cruch CR104s and so far it works like a champ!

To clarify for bridgeable amps, in general...
There are 'live' wires for positive and negative. Those are used either for normal or bridged wiring. These have signal on them
There are also 'dead' wires. These have no signal and are directly connected to the secondary ground). Those are used only when wiring normally.
For the Rockford (since the Zed varied), they had:
Left channel
Orange (left+ >> live)
Black (left - >> dead)
Right channel
Yellow (right+ >> dead)
Brown (right- >> live)
To bridge, you'd use the left+ and right-. Both the positive and negative bridging wires had signal on them.
