I prefer SQ setup. Open budget and any good brand will do.

Thanks
If focus is on SQ, I'd look at HU offerings from Kenwood, Pioneer, etc... not the off-brand Android HUs or any Chinese units, IMO. Depending on your budget, you might lose certain modern features like being able to install apps and such.

2nd, get rid of the underseat sub and use a real sub. Depending on what you listen to, a sealed sub sounds controlled and accurate overall, whereas a ported sub will sound louder and deeper, but has the potential to be sonically inaccurate. Port "whoosh" noises can also be a turn-off if the sub was not designed or placed properly.
