Got my setup tuned by Amplified Autosport via JL MAXX, what a step up from a dingus (me) with a single mic. This is my 3rd pro tune, and I come away astonished every time. This is the key to any great sound system. Stout install and tuning of basic Focals will outpace an Accuton front stage (about 9K for 6 speakers) that was poorly installed and tuned. All day everyday.
Run down of key developments during an install and final tune.
Tweeters and midranges were moved from their OEM locations to the A-Pillars in an off-axis manner. So far, this setup is great, even though our vehicles have no dashboard. Front stage kinda envelopes you. *Midranges perform best when the dash and pillars have some distance between themselves and your ears*
Esotar650 midbass units remain in the door cavities for now. I will fiberglass pods into door cards sometime this year. Midbasses do not care for door-mounted infinite-baffle setups, no matter what their specs suggest. They all sound their best in sealed pods or true infinite baffles, which means they have to vent to the outside via a cutout in the floor. Speakers themselves are superb.
Soundigital GaN 1500.5 amps are fantastic, very clean-sounding. I can't tell the difference between them and the A/B units that I had in the past.
Focal 5 KM front sub. This is a wild card at the moment; it hasn't been broken in yet, so I can't tell just how good it sounds.
SI SQL-12 in a new custom box is acceptable. I am still trying to find the best way to position it, and most definitely looking for a replacement. I want to move to shallow subs.
