Absolutely no rattle now anywhere

I just feel like the sound doesn't integrate well enough with the rest of the system, I want cleaner bass and a more blended signature. That's not to say they sound bad, it's just my itch for improvement.

Soundscape car audio in Plano,Tx did the work for me. Here's a little thing the had in their lobby that explains different types of enclosures.

For anyone who still is going to add subs, one piece of information I forgot to mention was setting up the Audio Control LC2i. The GTO feature for the LC2i didn't work for me so I bypassed it by tapping the remote turn on wire for the Mark Levinson amp and hooking it up directly to the LC2i's remote turn on gate. I hope this clarifies any questions for future subwoofer DIY's.

Am getting a delay with my sub. I got a jlaudio 10 with a alpine mvr 500 amp. I tap into the sub speaker like i did in my 2013 gs350. Now i have a f sport 2018 gs350 with mark leviton. Do i need to do something different with this setup
