I HAVE A 2006 G35 SEDAN. I AM ON MY 3 HU IN ONE MOUNTH. IS THERE A BUILT IN AMP ON THAT RADIO? 0 TO 15 NO VOL 15 TO 31 NOT VERY LOUD? i WAS TOLD i DON'T NOT HAVE A EXTERNAL AMP. SO IS THERE ONE BUILT INTO THE RADIO. IF SO CAN IT BE CHANGED AND WHERE WOULD YOU GET ONE. THANKS FOR THE HELP.

If its actually a Bose radio, there is an amp upside down on the rear deck, accessible from the trunk.. yth you would want to buy another blose amp is beyond me. I have one for 150 bux though

There is an amp in the car that the Headunit is wired to. Your best bet is not buying the OEM bose head unit and getting a Double DIN kit. Much better sound quality and you won't have a crap Unit.

Also,

I do have a Bose HU. I replaced it because of error codes. When I replaced it the volume on the HU was bad. 0 to 15 no sound 15 to 31 not much. Put old HU back witch had a GREAT kick and volume. When I put it back it did the samething as the new used one. Poor volume. I was told 2006 did not have externail amp in trunk. I took everything out to check. NO AMP.

Then you sir, must not have Bose...

you took down the felt on the underside of the rear deck?

no amp on rear deck = no bose

easy way to check. look at the rear deck. Does the middle speaker cover say bose?

Wow do i feel stupid. Your right. So i put my face on the bose hu. I will make the change tonight. Thank you.
