Also just found Metra supporting this infor for a 2010 ( i have a 2013)
Location Size Depth
Front 1 6.5 2.5
Front Tweeters 0.75 .5
Center 1 2.5 1.5
Rear 1 6.5 2
Rear Tweeters 0.75 .5
Was wondering if anyone had swapped out the OEM speakers and threw in new ones...
Crutchfield is saying the available options for the front and rear 5 1/4; 6.5 and 6 3/4
does anyone have more specifics for the A pillar tweeters and a more specific speaker size for doors?
1. Remove stock amp(s), sub, front door speakers, a-pillar tweeters, and center channel speaker.
2. Wire up a line-out harness for RCA interconnects coming from your headunit.
3. Install Hybrid Audio Imagine 6.5" in the front doors, mount the tweeters off-axis in the a-pillars. There is a bracket that holds the stock tweeters in place, you can reuse it and glue your new tweeters to it. You will probably have to either make or have someone make baffles for the front doors.
4. Get a Wicked C.A.S. box with a JL 10W3v3 in it for the hatch. You will lose a little bit of room but it's not bad, and is way easier than making a custom stealth box.
5. Get a small 4 channel Class D amp (JL XD 400/4) and run the fronts off Channels 1 & 2, then run the sub by bridging 3 & 4. I would make a panel to mount the amp on and put it behind the hatch trim where the stock sub was located before you removed it in Step 1.
Alternatively, for Step 5, you could basically go as crazy as you want to afford. Get an Audison Bit Ten sound processor and run the fronts fully active off the XD 400/4, then get an XD 600/1 to power the sub. You could also look at other speakers in the Hybrid Audio lineup. The Clarus series sound amazing, and I'm sure the Legatias are mind blowing...but they are pricey.
Anyway, just my opinion and all, but having gone down this road before and knowing what I know now...that's how I'd do it
2008 Audi A3 2.0T | K&N Typhoon CA Intake | Pioneer AVH-4300DVD HU w/ XM & DVD bypass | H&R Cup Kit w/ Sport Springs | Full LED Interior | LED License Plate Lights | Ashtray Delete | Rear Wiper Delete | Shaved Badges | Black Rings | Carbon Fiber Di Noc Wrapped Interior
Check out what this guy did, it was a good resource when I did my install (some things I did differently):
I personally have had a set of Hybrid Audio Clarus 6 1/2 Components for about 3 years now. I had them in my truck, then put them in the A3 when i got it. They are def. the best sounding speakers i have ever owned/heard. And yeah, the main reason i wasnt sure about the size for the rears is because i just put some speakers i had lying around in them, just to fill the door holes.
When i made custom baffles i made the baffle out of 3/4" thick mdf and did one layer with the custom cutout shape, then i cut out a spacer ring out of the same mdf and attached it to the baffle, so the baffle mounts to the door, and the ring to the baffle, then my 6 1/2 woofer to the ring. Because my woofers were so deep i had to do this, but there is more than enough space between the woofer and doorcard, even with essentially a 1.5in spacer of mdf between the door and top of the woofer.
Oh and if you use/make a baffle out of mdf or wood, give it a couple coats of paint or spray on bedliner so that it doesnt get mouldy or such.
