Looking for feedback from people in the general vicinity on A) how they acquired their soundbox, B) where/how they got it installed (dealer, private installer, DIY, etc), and C) how much it cost all-in. IIRC, I saw someone on some post in the last month or so say that they paid for the box and had it installed for like $350 OTD at a dealer. I would LOVE to pay such a small price for this upgrade.
