Hi Brett,
Do you have any pictures of your install? I'm interested in all audio related initiatives in our A2's, since very few owner really bother with it. I'm happy to read you're an enthousiast too. Keep it up ?
Yes, but it's looking terrible at the moment. Short version:
15mm plywood base across the boot floor. Cutouts to access the seat levers.
Left side has 14l box for 8" sub (correct size for that particular sub). The right side is split into to 2 levels. Lower level has a 4 output fused distro and a PG QX300.1 for sub; upper level 2 x PG QX350.2. Left for Tweeters, right for Woofers. Around 120W RMS per output channel available.
6.5" component set is from Axton, the ATC165. Woofers in plywood adapters, tweeters in cups on the a-pillars.
Speaker cables are DLS, signal cables from front to back are 4 connect; interconnects between amps are DIY Rean / Mogami. Should have done that for the signals front-to-back, too, but didn't think. Power is 35mm2 via 2 fuses to the distro block.
I can make the mirror shake. Calls sound good.
Slumber Party (NSFW!) sounds excellent - bouncy, nice tight bass, not shouty / screechy at all. This would be why I want to use these €100 drivers in the Octavia, too. Have to try
Silent Shout at some point, as it's got lots of subbass;
Ariane sounds excellent as does the unplugged version of
Hotel California and Herbert's
bloss geliebt. I can just turn it up and it keeps going - at some point I have to turn the Octy back down again as it's just annoying.
HU is a Pioneer SPH-10BT with the built-in phone holder (which also works really well).
Most expensive part of the system is the HU at €120. Speakers €100. Sub was €10. Amps I'm sure I didn't spend more than €50 each. Total is under €500. To improve still: fix and seal the front drivers against the inner door skin. Glue and paint same. Then fix the hum / hiss front to back with a 1.5mm to have common grounds. Then maybe the RCAs front to back. Think I still have enough Mogami.
