i checked setting on amp, head unit, checked wiring from amp physically to subs all looks the same. Only difference now is the sound terrible and quiet. Although if you turn the hu up loud u can def tell they are there, but sound terrible. Not throwing good clean bass anymore. Its hard to explain kind of thumping a little bit and not 'loud' at all. Ground from the amp is grounded to chasis wasn't touched either so thats good. If anyone knows about the monsoon system and how shops like best buy or future shop would wire the speakers without bypassing, is it possible they tapped into a signal affecting something?
