Question about Bazooka CS8A5 Car Subwoofer
I haven't installed speakers since I was a teenager... that was 20 years ago.. I pulled plastic stock speakers out of my toyotas rear deck... plastic speaker frames coming out of a metal rear deck.... The came out of the trunk.. not out of the top of the rear deck... So I tried to install my new Nakamichi 6.5" Coaxials the same way.. from the bottom instead of dropping them in the top... The new speakers have metal frames.. Well both went tinny and fuzzy within 15 minutes.. Did they need to be insulated from the metal rear deck or did they need to be dropped in from the top? I'm not sure where I went wrong... Mounted from the bottom the rubber gasket on the face of the speaker seemed to match up perfectly with the wholes in the metal rear deck. thanks for helping a old Noob...
I don't think the problem was the metal basket touching the vehicle sheet metal. It's very, VERY common for speakers to be mounted directly to sheet metal. I think what you needed was a spacer, not so much an insulator. Usually when speakers are bottom-mounted, there's a thick gasket on the front that prevents the speaker cone from coming into contact with the mounting surface. Its only function is to increase the distance between the speaker cone and the metal. Your first speakers probably lacked the spacer, so the cone was pushed up against the metal and couldn't move. This is what ultimately caused the damage. Keep in mind that even with your cardboard insulators, there'd still be an electrical connection between the mounting deck and the speaker basket, because of the metal mounting screws.

Take out the speakers and take an ohm meter and measure from both speaker connections on the speaker and see if there is an resistance or connections to the frame of the speakers. Next see how many ohms the original speakers where, and what these speakers are. If they are different, you may have blown the amp or the head unit. Good Luck
