I am trying to add an amp to a 99 Buick regal with Monsoon and am running into a problem with signal input. I want to catch the signal BEFORE the monsoon amp and it is not working. I dont know if this is even possible. I want to get a full range signal(20-20K) out of the system. I know I can get a line-out converter and put it on an output of the monsoon amp and it should work but I wont get a full range signal because of the internal crossovers. So what is the best way to do this? Thank you in advance.
