I just picked up some Crystal 40 that the cross overs have blown caps,
can someone help with wiring back together, red black green yellow blue brown
Cheers

Not to rain on the parade but if our member were up to that, he wouldn’t need help with the coloured wires. I hope I am wrong.
I hope OP can show some photos that help us follow the circuit. I'd be glad to do it. 😉
Please take more than one of the back of the board, and more than one angle around the component side, because shadows and other things can make photos difficult to use.

Excellent. Ok, red and green appear to be the lower woofer. Brown and black are the upper woofer. Connect the black and green to the negative terminals on the woofers.
It's difficult to say which polarity to use with the tweeter. You might have something close to a fourth order crossover there, which would want normal polarity... but I'd really try them both. Do you feel confident with that?

Yes thanks heaps.....the 8.2uF has the plastic cover coming off and something coming out of the 20uF cap,
I think i should be able to test in circuit

The 8.2 is right next to a resistor, perhaps heat affected the cover. If you suspect heat exposure or you see any expansion/leakage, you ought to replace them. That goes for a change in value.
Thanks, I cant find local to me a 8.2uF but a 6.8uF 100v will that lower or higher the tweeter circuit on the bottom
end or top end of the response....
