OK. I have a dumb question. I was casually looking around in the trunk area of my new G35 and I noticed that the Bose speakers on the rear deck are enclosed with the same material that is used to line the trunk area. From my past experience, rear deck speakers need to use the air volume in the truck to pump out the bass. I think the material used to cover each speaker is limiting the output capabilites of the speakers. You simply cannot get deep and accurate bass response out of any speaker unless it has enough air volume to move within the cavity that it is mounted in.

Thoughts?

 

normaly they dont need all that much airspace for the 6x9s, in G's Bose case, i dont think it matter much at all, you cant really ask the 6x9 to "pump" much bass began with, let alone "deep" and "accurate" bass note...s.w.

Understood. Although I have an old pair of Jensen 6x9s in my '73 Javelin AMX and they pump out some decent and accurate base. Has anyone tried removing these covers to see if there is even a marginal improvement?

 

ummmmm...maybe you can try, and let rest of us know, it improves or not, you never know tho. it might help some...s.w.

by the way it was not a "dumb" question at all.

I might give it a shot. If I do, I will certainly let you know how it goes. Thanks!

 

the cover has holes in it and is not airtight. The 6x9's are already using the entire trunk for an enclosure.

 

So it is a breathable material? I was wondering about that. I't does not have any physical holes in it.

 

Take it off anyway and tell us if it's possible to remove the rear speakers that way, rather than tearing out the whole back seat!

 

Mine has holes in it.

Also, you have to go through the rear deck to get to the bolts on the speaker. It is a pain in the ***.

 

may be a dumb question... is there any harm in taking off these covers? because i have 2 w6's in the back, and these covers rattle like crazy everytime they hit.

I'm careful with my trunk so nothing will touch the speakers if not covered.

 

I removed mine to add an enclosure.........but i ran one side without the cover for a while.......

the problem is that the rear seat also breathes into the cabin, so the rear deck speakers act as an infinite baffle.......not very good for bass......

 

Question for you guys. I've heard people putting some 6x9 three and two ways back there. Now, isn't this a waste? You are basically shooting the tweets and everything else up into the rear deck. Also, have you guys noticed why there is a huge gap/empty space at the bottom of the opening, at the rear seat?

I was just curious if anyone know why that is?

Oh, I found the answer to my 6x9 question. I have the non-premium so I don't have any 6x9. Good thing I guess as this is a waste of space underneath the rear deck and if you remove it, you have two big holes where sound can get in. This is the reason why I opted not to get the premium. I knew I would be upgrading everything later.

 

Spent the past week fabricating my component install on my drivers side door. After about 1.5 weeks working on that (and getting weird looks from people who saw me driving around with driver door stripped down to bare metal) I'm ready for a 2 hour install to get my passenger side up and running.

Short of it all, after hearing the excellent quality from ONLY my drivers side component set, I've been convinced that I do not need any speakers in the rear. First, rarely anyone is in my backseat. Second, the component sets are such good quality, I think rear seat passengers will enjoy hearing excellent sound from the front (where sound is supposed to come from anyways) than mediocare sound from the rear.

I'm going to remove the rear deck speakers & trunk-side covers all together to allow for better pass-through of the bass from the subwoofer while maintaining stock look (and heck, buying back some more trunk real estate!)

 

I can see why you would want more space back there but leaving the gap there isn't a good idea on noise. You will get alot of road noise from the trunk so leaving the rear deck space open from the speaker removel is inviting more unwanted noise. The more noise you have, the louder you will have to turn your music up, and so on. Remember, bass is un-directional so you don't need to have any open space. Your trunk will act like a band-pass (don't ask, it's complicated) type encloseer (although more like sealed enclosure but there are alot of gaps in there trunk anyways). That's just my thoughts.

As for the rear sides, I'm still debating on that one. What I'm planning to do is modify it to hold a 6x9 sub. The rear deck has the 6x9 sub but is pretty much useless because it is free-air and requires alot of power to do any good. Now, the rear sides can almost act like a sealed enclosure so I may go that route. Tough choice. I heard the rear only has about 2 1/2 inches of mounting space but there is some metal brace that can be knocked out and so, I may do that. Guess we'll see. Who knows, maybe I can modify it to fit an 8 inch sub

 

I don't think that with proper sound deadening and weather stripping that this will be much of a problem. I think I'll get more road noise from my tires then from my trunk.

I understand that bass is non/omni-directional, but the G coupe trunk is fairly sealed from the cabin. This requires the sub gains to be turned UP to "power" it's way into the cabin. By removing the rear speakers, you provide a way for passage into the cabin.

What do you consider a "6x9 sub"?

Stock or in your car? Do you have a sedan? Coupes have two speakers in the rear deck, not a single "6x9 sub" (which I'm not sure what you are calling a 6x9 sub anyways).

Can you explain this?
