after some further listening, judge feedback, and local audio nerd feedback, i discovered that my mids were crossed too low, the enclosures were too small, or the enclosures weren't vented enough. the biggest indication was the bloom/boom centered around 500hz.



some local audio nerds suggested i try to vent the driver better into the door. so i got a blessing from JT and opened them up a bit to breathe into the door panel. i punched an additional 1+" hole directly into the door panel. should be almost 2" diameter total vent.



thankfully i've got spare door panels:






end result? solid response down to 100hz!


lower midrange tones sound more pronounced. midrange notes aren't as pronounced. whole stage sort of relaxed a little. positioning is a little better. stage height raised up a bit as well.

also note: it's funny watching these little c3 drivers blap out the lower notes (no lowpass crossover)

i should have a bigger update in a couple weeks.

maybe i'll get a tune and some wheels, then people will take it seriously


*bags and wheels

It's cool to see something more extensive tho - Ive never looked into audio beyond adding a small sub so it's nice to see something way more thought out.

maybe check out some sql (sound quality league) events in your area to see what people are doing. there's a few golfs around, all with different approaches.

you say you're from ohio, there's an event 07/15/17, 08/13/17, and a two-day state finals 09/23 - 09/24/17. i don't think michigan has any shows but you could check the surrounding states as well.

the lower midrange distortion was much better but not completely gone. so, i grew the vents another 1/2" and it's now gone.



i ran 4ch rcas up front, removed the speaker-output pins/wires from the harness, installed my own, and put on female rca ends.



while it was apart i ran a usb and director cable for a new dsp. just in case, i ran a toslink/optical cable. oh yeah, i got a new dsp.



so now it's fully active.

director is double-sided-taped down right now:



with all speakers disconnected and the HU's output set to line-level, it's much clearer.

i think i'll two-for-one sell the bit ten d in a few weeks. (get a free bit ten!)

one of my goals this year was to get an 80 in meca sq modified.

i worked on a tune over the past couple weeks, mostly for tonality.

i went to a triple point event yesterday and scored an average of 79.92. so close but average of 78, 80.75, and 81.

i'll take a closer look at feedback soon and see what else i can work on tuning-wise. i got feedback from others this week as well.

At the beginning of this thread I was excited about a SQ build in a GTI and you didn't disappoint me. l just got my 2014 a couple weeks ago and so far have built my box and installed my JL XD700/5v2 on the OEM RCD310. I also agree, it works ok but does create a bit of distortion and not the cleanest signal. I have my Hertz Hi Energy's that I had in my Passat that I plan to put in, just gotta find the time to do it. Definitely going to be keeping my eye on what you do. Great work so far!

Here's my box in the drivers side area:

Are you still running the horns under the dash with the kicks and sails?
