Just finished installing JL Audio Stealthbox in my 2023 Tahoe HC. JL recommends using their mono amp...XDM300. I went with Kicker CXA400...same specs as JL amp but $300 cheaper. Saved more money buying an "open box" unit on Crutchfield. I mounted it same as others have done on this forum...on top of sub box behind trim panel.
