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

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?

      Why are you so adamant on going M12? Why not follow Brad (GTSBoy) suggestion. You're talking moving from a 1/8" size, to a 1/2" effectively. 4 times bigger. Why skip the commonly available sizes in between? The bigger you go, the more likely you are to strip the threads out at a later date, as guaranteed, someone will put a huge spanner on the M12 and really tighten it up, and you're only in thin wall, so not a lot of threads to engage!

      Hi. Yeah thanks. Car is already at tuners and it staying there to resolve "many" issues they do not like. So it is in a good hands. Getting a good tune on that Nistune ECU too so the car would be good. Just needs a little tune up and love.

      Probably gonna remove manifold and turbo. I’m not sure if I can get M12 x 1.5 air tight. Could use high temp Loctite 246 or something similar, but I don’t know. Maybe it’s just best to remove everything again and weld an 1/8NPT on there instead.

      Yeah, saw the ratios, not impressed. Would like the punch I have in the first gears now. With those ratios it won't be the same.  Also want the h pattern gearing, or at least a quiet gear set that don't need to come apart for service each year. Looks like the only "reasonable" way Is a 8hp70 transmission, but where is the fun in that🤷‍♂️
