I think I fried my mids today. Fresh install.
Playing Tool at moderate volume, POP.
When installing the guy mounted the crossovers high and under my dash, hid them very well. Of course in doing so, he disconnected the wires to the tweeters! I don't think he noticed since he left the stock front tweeters still wired.
It sounded horrible to me and once I snipped the stock tweeters it obviously sounded even worse.
I don't know if this is related to me blowing the mids (before I discovered the tweeters were disconnected) or not.
Another interesting point - Most first thoughts would be that I over drove the speakers (but it wasn't THAT loud). But, the cruddy stock rears were connected to the HU and they're fine.
