system blowing ENG INJ fuses...

[rtillaree 10+ year member]

this started once i connected my new PPI 4 channel, im guessing that it is drawing too much power coupled with the mono block...but im not sure just yet...

basically i have blown 2 30amp fuses, both of which were for my ENG INJ which sucks as you can imagine doing 75 on the highway and losing fuel injection is not a wicked fun event...not 100% sure what the issue is...

i didnt think my audio was on that line in any way...but i guess it has to be somehow as the fuses only pop when the audio is on full tilt, half way it's all good, or at least it seems to be...

i ran through the standard re-seating of all audio cables, made sure all of the wires were connected properly, none of the wires were loose, all of the fuses and fuse holders are fine...

so my only guess is that it is just too much power, i thought i had taken all of the precautions but i guess i effed something up somewhere...

any advice?

im guessing that when audio excellence did my initial install they must have tapped into a line in the rear which is running to the injection fuse in the main box, it never went out before because the other amps were lower draw, the PPI is like 6 years old, and it seems to draw way more current...
