Bose Head Unit But No Amp Help.....

[HotXR6T]

Hi All,

I have a unique problem with my new V35 Coupe. It had a JDM double DIN unit in it that was removed and replaced with a Bose premium head unit. The car is originally a non-premium spec car so had no amp. Problem I have now on getting the car is the audio is too low to hear at highway speeds (as there is no amp) and just distorts if I try and turn it up. I can get to about 21 on the volume scale before it distorts but the volume is just too low.

I am not after any top end audio system, just something for everyday driving to and from work etc. Any ideas on how to sort this out without removing the lot and going to a JDM DD or something similar? I was thinking of somehow putting a small amp in to boost levels to an acceptable volume.

Your help is much appreciated.

If it is a bose HU in a non-bose system, the HU can be modified to turn it into a 'non-bose' HU, but it isn't easy. They are essentially the same internals with some minor changes.

I have a bose HU in a non-bose system, and yes the volume is down compared to a correct non-bose HU, but it isn't that bad and I rarely need to run it over 20. It also shouldn't be distorting.

The biggest issue is the non-bose HU had a larger fanned heat sink for the audio amp IC. The Bose HU doesn't.

Thanks for the reply. Driving around town I doubt it will be a problem but at 110 kph, it just isnt loud enough to hear clearly. Are there any instructions regarding modifying it? And will that raise the volume?

Sonicii, Is this the modification you are talking about?

Fantastic. Thanks sonicii. That I can do and it will save all sorts of hassles. Do you have any opinions on this?

No idea sorry, I don't have Navi on my car.
