Mr.Apex and and to others here who can help this is my protect circuit having problem,when i first turn it on the relay wont activate but when i turn it off and on again 24v now present on relay coil and turns on i measure voltage on regulator 7815 +15 v present„7915 -15v absent having lower voltage and 7912 +12 present,then i 2xcheck my components and found 4148 diode in reverse position so i correct it and placed it on copper side due to track damage on copper but still same trouble,and while im trouble shoot i accedentaly forgot to connect the bd241 and turn it on after 5sec relay on with 24vdc and +-15vdc is present what could be the problem i need help with this my new 2 b500 is waiting any help pls.

H900 and B500 have inverted output phase for useing with B2181 and B181 subs. Speakers in B2181 and B181 are in reverted position for beter cooling.
If you use B2181 and B181 with another amps you must reverted (+) and (-) on speaker terminal or you can turn around speaker in standard position, also if you use H900 and B500 with another speakers you must reverted (+) and (-) on speakers terminals or amps output terminals.
Regards
Apex said this on h900 forum maybe it will you this
