Speakers Below Quarter Glass?

When i removed the trim panels from the quarters in my car awhile ago along with the lower panels, I noticed there was plenty of room to put a 6x9 or so speaker there.

When i was flipping through my chiltons manual i noticed (drawn) picture instructions about removing a quarter that included a speaker and grille in this exact spot...

Was this available on 83-86 foxes?
I don't recall ever noticing a grille back there when looking at pictures, or seeing any in the junkyard, then again i haven't been looking until now...

Would be great if they did make them on the four-eyes.
saves me some work, as i was gonna fab a couple mounts up at some point...

Anyone know?

Are you talking about under the back quarter-windows and just above the rear "arm rests"?

Ive always kinda imagined putting speakers in that spot.

I have 6 1/2" speakers mounted there on my car-my armrests are still there.

Thought about it and would have done it if it wasn't for the fact that sound quality/imaging would turn to . I don't have a rear stage any longer with exception of the subs - no perceived missing sound behind me either. It actually sounded better after I took the 6x9's out. I tried putting them back in a few months later but tore them back out after 30 minutes and sealed the trunk off.

A couple 6" speakers would fit there fine but nothing too deep unless you want to build it outward through the armrests with baffles or something. Don't forget to fill the empty cavity up with something so the rear sound waves won't wreak havoc. Closed cell foam works great or use some Great Stuff sparingly (put a heavy-lined bag into the cavity and fill with foam - without this you'll never get that  out if you want to) so you don't damage the quarter panel from its expansion.

I have seen spekaers mounted in the head rest on the fornt seats facing the front window and after watching pimp my ride 9 TVs on the roof of a 69 Cougar i really see no harm in putting spekaers there on are cars.

Seek -you are so right about removing the 6x9's. I had Diamond Audio component's in the front of my last bird and a pair of 5 1/4's (mids) in the rear turned way down just for a hint of "rear fill". I have met few people that can appreciate a good front image in a car. Most people have their rear speakers doing most of the work. Just curious how do you have your Sub Bass arranged? I had a 3 chamber isobaric box ported through the rear factory holes in my old bird-but that was in 1994! I still am exploring new ideas in my head.

Heres how I custom mine I put them under the arm rest :D Because I don't wanna lose those :O.  The Speakers r more on the bass side so it gives it a kick in the back seat where the sound really rocks...  I mean once I put these speakers in my sound was super great after that... and I never had any problem where they rumbled the plastic r anything like that like some people say u will have :S...  Also mine r 6 by 7's....

Two TC Sounds TC-7 subs (10") mounted infinite baffle behind the rear seat. They're bolted in between two routed-out 3/4" MDF boards with the edges of the boards sealed with foam. They sit about 1" back from the rear seat braces that after attempting to remove, I left them in there. If I move up to a 1000w amp, I'll need to remove them for the additional excursion. Currently they blend in perfectly (NO EQing done in the car as it sounds great being flat) with the 75w (8 ohms) I have going to the doors and 25w I have going to the "tweeters" (currently just using some decent dash speakers that at the moment have trouble keeping up with the doors) but the front stage will be receiving more power soon.

I won't hijack this thread - just giving my thoughts on the reasons NOT to go with rear speakers. Proper front speakers will give you the illusion that you have rear ones. I did mine on as much of a budget that I could. $20 dash, $100 door speakers, $300 in amps, $80 subs - all used parts. If you want to talk more, send a PM.

If you must go with some speakers under/in the arm rests, try to stick with circular speakers. If bass is your liking, mount some ED 7kv.2/3's firmly into where the rear 5x7's currently reside. These will fit well with a MDF baffle and give you plenty of low end when giving them 100w a piece IB. It won't sound as great as a fully-custom setup or get insanely loud, but you won't have a lack of mid/sub bass - they play with authority below 30hz as tested with test tones when I had one testing in the doors. They're not much/clear beyond 300hz though so a midrange driver is needed.

Also, be careful with how you wire up additional speakers. You can't just splice the output from the headunit to another 2 speakers in the back - you'll likely be at 2ohms or less at this point. Use four 8ohm speakers, there shouldn't be much of an issue though.

Instead of 6x9s in the rear deck, you could consider 6 1/2's (round) in there and leave the rest open. I had that done with a pair of MB Quart Discus series on a custom mounting plate. The autosound guys thought that it was a better compromise for purer sound, since it's just rear fill and the sub is doing the brunt of the bass work anyway. They felt that leaving the rest open made more sense than closing it off, i.e. let air flow from the trunk area to allow heat to escape the amps and a little extra bass from the sub at the near-midrange area.

as for the speakers below quarter glass i thought about it a few times but not like the picture posted behind the cloth in the center but i don't think it would be worth it for me.. i'm running Dolby Digital 5.1 and DTS 5.1 and running 120 watts in each door and 120 watts on each side on the rear deck..

reason I put the speakers like the was because those speakers r mostly bass and when u crank it with friends in the bak they feel those babies shaking the seat :D  Also those were free speakers I got from a friend... didn't know where to put them so I found a spot..  lets just say in the back seat of the car you can go death when u crank
