It took me all day and a lot of referencing old posts for speaker wire colors, but I managed to get some decent sound from this cheap setup!
Since I’ve only got FR & FL channels, I split them at the amp and put a low pass filter on speaker channels 3 & 4, and wired those up to the kick panels and subwoofers.
Channels 1 & 2 are wired up to the tweeters, doors, and rear mid speakers.
It’s not stellar, but the signal is clean and I couldn’t hear any distortion at higher volumes.
I’m going to (eventually) update this thread with an easy to read speaker wiring diagram for the next fool that buys a trashed DSP Z4 lol some of the reference sheets being shared around are not very easy to read and even worse if you decide to print them.
