Bazooka 6 1/4" 4 Ohm DVC Sail Panel Install

Compliments of wssix99 @ www.ls1tech.com

Below are some pictures and methods I used to install new Bazooka DVC speakers for my 99 Firebird Monsoon system. Overall, the install went smoothly; however I did have to make some hardware modifications and nibble some sheet metal to get them to go in perfectly. Hopefully, this will help others from having to do some of the re-work I went through.

Before I get started - I'd like to thank Ian from Kee Audio (he's a lifesaver) for tracking these speakers down. They are a great fit and sound great! I've had torn speakers for a couple of years now, but to the best of my recollection, these new speakers blow away the stockers.

Below is a sampling of the "new stuff." I had some spar connector parts & tools lying around, so I made a custom harness (to replace the OEM wires) in anticipation of a future wiring upgrade to the rest of my car. This is probably overkill for most people as the tools to do the crimps cost almost as much as the speakers. (If anyone is interested in more info on building the harness, please let me know.) Most will want to re-use the original wires/harness, which can be soldered to the new speakers.

I also used a Nibbler Tool (can be purchased from radio shack and required new speed nuts from my local auto parts store. (Dorman Body-Tite! #6 Speed Nuts #45401)

The bolt holes in my new speakers measured 6 1/4", which is the exact measurement between the stock screw holes on my '99. So, I was off by about the thickness of the screws. To give a little more play in the holes so the screws would go in straight, I used the Nibbler Tool to take just one bite out of each hole. (Others may choose not to do this step or may not need the additional room, so I suggest checking the measurements first.)

The distance from the screw holes to the speaker carrier on the Bazookas is also a little shorter than the extended slots on the stock speakers. In my situation, the OEM U-Nuts were too deep to align with the Bazooka's screw holes, so I replaced them with shorter #6 speed nuts from my local auto parts store. I re-used the original screws, which at 4.2mm, are slightly bigger than a #6 hole. However; the design of the new nuts allowed them to work perfectly with the stock screws.

I also had to modify screws by taking off the washers. After originally installing the stock screws, the washers bit in to the speaker's suspension and overlapped the metal rim around the speaker. The washers actually cut completely through the lip in the suspension, which is bad. (So... I'm now hoping the tears don't get any bigger.) I highly recommend this modification. The washers are very soft. To get them off the screws, I took two vice grip pliers and clamped them down to either side of the washers. Slightly twisting the pliers axially in opposite directions was enough to tear the washers apart.

To install the speakers, I positioned the new speed nuts, using tape to hold them in place. (They don't have the nice captive lip that the original u-nuts have.)

Removing the sail panels will make this install much easier, but I chose to work around them. The catch is making sure the grill holders dont tear in to the foam suspension on the speakers. Once positioned in the holes, the speakers screwed right in. (Before tightening, I pulled the tape out.)

To finish off the install, I used some small pieces of sound matting to cover the wire hole at the bottom of the speaker, letting the wires come out over top of the matting. (not pictured) I found that this helped tighten the sound up noticeably. There's still a slight echo in the sound from the speakers, so I expect people choosing to put sound matting behind the speaker will be additionally rewarded in this regard.
