No bass. No power.
I had the rear door speakers replaced but no improvement
I guess I’ll take it to a car audio shop to get an amp installed.
And switch out front door speakers.
The Rosen unit has a few quirks to it.
You find that?
Plus. I’m going deaf. So mb I’m the problem
My experience was a noticeable improvement over the factory HU on the Bose amp.
The Bose sub under the center console definitely came alive with the addition of the Rosen HU.
Did you install the Rosen or was it already in the truck when you bought it???
The Rosen's come with several different harnesses. One for the Bose system and one for NON-Bose.
The one for the Bose system basically runs the Bose amp off of the pre outs from the HU. The NON-Bose harness runs the speakers off the HU's internal amplifier.
If you run the Bose harness on the non-Bose truck the out put (power) would be extremely low. Conversely if you ran the non-Bose harness to a Bose amp it would overpower it and you wouldn't be able to turn the volume up more than a couple of clicks before the speakers would distort.
When you say a few quirks what are you referring to???
My only real complaint is that my Navigation takes longer than it used to on initial boot up.
Originally it took maybe 30 seconds to a minute to boot up after starting the truck. Now if I press the Nav button right after starting the truck, the Nav will take upwards of 5 mins to finally boot up and become usable. Once it boots up it is good to go.
