Default Bigger speakers in the hatch area?

Anyone tried stuffing larger speakers in the quarter panels of the hatch area? Factory size I believe for S4-on cars is 4", at least that is what mine are. If I remember correctly, there's an aluminum ring mounted to the fibrous material of the leather panel. I suppose you can just cut that ring bigger to accommodate a 5.25".

FWIW, there isnt much need for them...


Theyre so far away, its an imaging issue.

i imagine they were there so the back seat pax could hear "normal music"...

I think depth will be the problem for bigger speakers on the rear of the quarter panel. You might be able to go bigger in diameter with one of the shallow mount speakers but I don't know what that'll buy you in terms of sound.

As for whether or not they're needed for 'good' sound... I think you'd need to do some actual analysis with microphones and stuff.

On the front of the quarter panel the '89+ cars have a 6" and a tweeter in addition to the 4" on the rear quarter. There is more room in the front quarter location.

What do you think you'd gain or lose with bigger rear quarter speakers or no rear quarter speakers? What are you trying to achieve?

I had a spare set of Pioneer A-series in the garage from Christmas. It was a present from the in-laws. I guess if they don't fit, I'll make sure they get their money back with Amazon.

I put some 6.5"s in the quarter this weekend, tossing my old Infinitys that were starting to deteriorate. Amazing how modern [and new] speakers sound versus those of decades ago. My front 4" components are coming in Thursday, but those are D-series Pioneers.

Honestly, I'm not big into bass and big money into sound since I usually drive with the radio off to enjoy the engine and exhaust more.

Unless you're trying to turn them into some sort of subwoofer, I don't think the result would be good even if you got something to fit there.

You might need good or big speakers in there for the system to sound good but if your original rear speakers are shot the entire system will sound bad.

I've seen 5.25" speakers in the rear quarter that came with the raised speaker cover. It stuck out about 1" so the speaker depth wasn't bad. If you want flush mount, that might not fit.

Very little mounting depth there. Original speakers in the OB's were those oddball magnet up in the cone shallow depth things.

Alpine 4" 410S will fit since they are a shallow speaker. Any 5.25" speaking is going to stick out.

A 4" is adequate in this location since they are basically just tone-up speakers that help round out the high frequencies throughout the cabin. Yes they are far back, but the glass in the hatch area will reflect the sound to the rest of the cabin. I have always run mine and notice the difference when they are not in use, it's not major but they do help.

Since I don't have that location available in my car, I put 6.5" composite Focals in the rear quarter area. Reinforced the panels with wire mesh, then covered the mesh with some rubberized material I had around (might be tool box drawer liner), then installed the speakers with BoomMat enclosures behind them. Running high speed with the top down, you need serious volume and power to hear the music and I didn't want it all muffled and boomy. In addition to the rear 6.5" composites, there and front 3-way component speakers in the doors and a Sharkwoofer in the trunk, all driven by a 1,000 watt 6-channel marine amp in the rear console (modified an rear A/C car console so the amp could vent heat).

Not an ideal sub placement.

The panel isnt stiff enough, and no volume behind it.

They were just imaging for back seat passengers.

Speaker cloth over the hole from behind, grille back on, looks like a speaker from above.

Oh, I know. You'd have to modify that whole area pretty heavily to do it. I just hate systems that blast high frequencies at you from behind. Several feet behind, even worse. Back seat passengers can wear headphones if they don't like it!

Those wayback speakers always puzzled me. They are designed to be "mid-bass" (read: midrange) drivers in a 3-way component rear speaker. But 2" tweeter/4" midrange/6.75" bass speaker like in the late 928s is not an optimal configuration - a modern 2 way component or even a quality coax is superior in every way to the OEM speakers.
