G35 coupe audio question

[smockers83]

Normally this is something I would find out on my own, but since my car's in storage and its cold (in MI), I'm not going to start taking things apart any time soon. What I'm wondering, if anyone out there knows, is if the rear deck of the 06 coupe has the 6x9 cutouts whether you have the Bose system or not. I would think so since it would reduce costs (fewer specialized parts), but I just want to make sure so that hopefully I can get some ordered soon. I don't have the Bose system and want to put 6x9s in and do away with the rear side panel speakers for now at least.

crutchfield only shows that there are two pairs of speakers in the G35 coupe. For both bose and non-bose

Also, I wouldn't recommend 6x9s even if that was the cutout size. I'd recommend 6.5" components

[smockers83]

try crutchfield again (clear your cookies after you go back or use the change vehicle link) and you'll see with the Bose system you have the doors (6.5/6.75"), rear side panels (6.5/6.75"), and the rear deck (6x9s) as opposed to just the doors and rear panels without the Bose. or check out the link below for the Bose setup. and a Bose system would have more than 6 speakers (the corvette has 7). i'm going with 6.5" or 6.75" components in the front just for the sake of upgrading and would like to go with 6x9s in the back to add bass without going to subs (due to already limited trunk space), hence my question about the rear deck. maybe there's a difference in taste, but why would you recommend 6.5"s over 6x9s in the back?

an interesting thing, imo, that i found on crutchfield is that the 6x9s for the Bose act more as subs than anything else. only low frequencies are sent to them. not that this changes my wiring options using the factory wiring since i have no 6x9s to begin with back there, just thought it was kind of interesting. hopefully i'll make enough money over the summer (college student income) to get an amp instead of underpowering new speakers with the crap HU, which is not cheap to upgrade either. i hope that the people buying 07s and up won't have to replace the a/c controls just to install a new HU.

I'm not absolutely positve if the holes are there or not, but I don't see why they wouldn't be.

The only problem I can see is are there grills on the rear deck for the speakers? If not you'll have to make some.

Also, since you mentioned these are mainly for bass i'll make a recommendation.

The tang Band 6x9 sub

It will require an amplifier. I'd recommend between 50w and 100w RMS to each of these.

Note: These will ONLY produce bass. So unless you keep the rear side panel speakers you won't have any rear "fill", not that i'd consider that a bad thing. It's just that some people like to have the rear speakers, some don't. I personally like having rears.

I have an 05 with the Bose system...The rear 6x9s are full-range speakers. The Bose setup uses the rear seat 6.5" speakers for bass. If you were to add a sub, that is the speaker leads you need to use for the input.

I would take the car to a stereo shop (not best buy or circuit city) and have them install everything. Most amp companies are coming out with decent amps that can use speaker level inputs or low-level (RCA) inputs. Personally, I love my MTX amp and sub set-up. I still have room in my trunk, but no fold down seat access.

Some will disagree with my setup, but replacing the mid/high speakers doesn't give you the bang for the buck as adding a sub.

Anyway, you're best bet is to look in your rear deck for mounting holes. Most 6x9s will come with a grill, so pick one that matches the ascetics of the interior of the car.

I agree with PoorMan Q...get a decent component set instead of the 6x9s, the sound is much smoother.

[smockers83]

interesting that the 6.5s in the panels are actually the "subs". seems kind of illogical to set up a good sound stage that way, but that's just me. i'll have to start comparing 6x9s and components i guess to hear the difference. my original plan was to have full range 6x9s in the back that are voice matched or whatever to the components that i'll put in the fronts. i've been thinking about the jbl gto's. and i would never take my car to circuit city or best buy or any other chain that installs in house.

[PoorManQ45]

You can reverse the soundstage is you want

I personally would try that as IMHO having speakers on the rear deck are jsut too overpowering to the rear passengers

Personally I'd go with those 6x9 subs I linked to. They offer about the same output as a single 10 or low quality 12, they they are pretty darn clean.

Tang Band is known amongst the DIY crowd for making really good drivers.

Funny you say that...in the new G35 sedan, they put 10" drivers in the front doors. I guess it still lacks real punch though.

I'd just install a sub. You don't have to loose your trunk, there's lots of options. The spare tire well is a popular choice. There are stealthboxes (MTX has one with an onboard amp) that fit in the corner of the trunk. Or you could go the 6x9 rear deck sub route. The only thing is the output will not be as loud as a sealed box enclosure in the trunk. (They use the trunk as the enclosure ie "infinite baffle")

This is my setup...

Believe it or not, I modeled the Tang Band 6x9s in WinISD. I gave an estimated 15ft^3(probably will end up less). They were able hit ~105dB from 30~100hz BEFORE cabin gain. So, they're pretty darn capable.

I know they won't be able to rattle the cars around you, but they will give you a punchy bassnote.

[smockers83]

yeah, i don't want to be rattling cars next to me or people walking by. i kind of want it like a club, you can kinda hear it outside but you have to get in to join the party. and i'm trying to keep it tasteful i guess like the car. so actual subs are out of the question because i know if i get them i'll pound them. don't get me wrong, bone rattling systems are awesome but i don't feel it fits a G. and i didn't buy a coupe to think about rear passengers, if i really wanted to do that i would have bought the sedan haha. but whatever i get for the back, components or 6x9s, it'll be full range, not just subs/mids.

[PoorManQ45]

Why not try the 6x9 subs?

They don't require any enclosure?

If you don't like them Partsexpress has a pretty liberal return policy
