No offence I did not think to look at that...and I will change my user name once I figure out how. I have that mod sheet but it seems only to be if you want to use the LPF (Sub Channel) for the M25 or some combination of that. I just want the amp to be for high pass only using an external crossover ...

I am in the process of re-capping my route 66 amp. I have always wanted to bridge the M44 section to run the front speakers and leave the M25 to power the rear. What if anything needs to be done to bypass the low pass crossover on the sub output to achieve this?

Thanks in advance.
