Model I’m using for my NV56 truck. Epoxy a board slipped thru dome light opening.
Thru same access install a LAIRD NMO34b with WD640b whip and Springb.
FT240-31 ferrite wrapped eleven times with tight radius coax as RF/CMC choke at feedpoint.
Antenna location beats all others. Can be removed and capped. Lasts a decade or longer. Tall enough to perform (a CWB27 Laird if you find one on eBay).
12V power (fused) down A-pillar and out door opening for AM/FM antenna thru fender to BATT. Dodge recommends NEG to that side fender attachment,
not batt; unfused. I’d run at least 10-AWG (marine-grade).
DRX-901 speaker under drivers seat firing into footwell. (Snake audio to drivers side B-pillar). Internal speaker is junk, and truck stop speakers not far behind.
It isn’t the words that matter . . . it's how they’re said and what that portends
Stryker 65 or latest 75 microphone.
On back-side of radio, second filter:

Most noise in mobile is via coax. Treat both ends.
If that 955 isn’t V.2, it’s best to get one that is (or the clone that’s the latest ANYTONE “short case” V.2 AT-5555N2) as
integrated NRC has so changed 11-Meter the past year that without this type of DSP filtration, older radios are simply obsolete.
“Power” to get heard is what’s not needed (past 50W or so with above antenna + location) its
clarity. Hear what others cannot, and get heard via same.
I cannot emphasize this enough.
The quality of the installation is what matters most. The
systems into which the radio is just a component. Antenna design plus mount location and noise treatment outstrips all else. Clean 12V is second. The radio (assuming NRC) is last.

The radio rigs I hear and converse the farthest are of this model. It ain’t Fat Fred and a 600W linear with a 108” chained to the bumper. Or (laugh) the one with the toolbox antenna.
It’s Grannie Gertie in a minivan doing OVERSIZED pilot car duty with an export radio and permanent roof-center antenna.
1-2/miles of warning on a high volume road ain’t enough distance to avoid problems. Needs 3-5/miles on average or better to avoid entanglement. Huge pile-ups are now the norm. Daily.
It’s nothing uncommon for me to hear of problems 15-20/miles out from two men discussing what one left behind him ten miles farther back.
NRC changed the game. It’s easier to listen all day, and now the radio can adequately filter what it receives (assuming no antenna compromise). It’s also far easier to deal with atmospheric
