Hey guys I'm having a very hard time figuring out how I should wire in my new amp and sub into my 1998 Grand Prix GT. I have the premium sound system with the extra tweeters and 6x9's in the rear, everything is stock though btw. I read that Grand Prix's with the premium sound have a monsoon amp a low-pass crossover that supplies the 6x9's. If my car has this system, then I want to tap into those low-pass wires to feed sound to my new amp and 13" woofers. So yeah can you guys let me know if my car actually has the monsoon and crossover and if I do where it is because I think I have it and I cant find it. Thanks in advance!
