I have a PPI PCX-1250 amp and i just installed a Eclipse 8443 deck, it has 8-volt preouts but thats fine seeing how the PPI has input sens. up to 12volts. My problem is for some reason it wont accept the signal sometimes when i turn the system on. I think that because the 8443 is known for giving pops on turn on/off its causing the amp to go into pretection mode. I have a secound older PPI amp and this problem doesn't occur. Any suggestions?
