MDMetal Posted March 28, 2017 Share Posted March 28, 2017 So I have my new HU installed and did the buster mod, but im finding the volume level is crazy, step one feels like its already 4-5. My HU only has front phono out so I had to do the mod anyway. I'd really like to reduce the volume by 50% or so. Does the cars main amp have a gain control on it or is it fixed? Even on low volume im hearing some static hiss louder than with the bose when no audio is being output. Quote Link to comment Share on other sites More sharing options...
Keyser Posted March 29, 2017 Share Posted March 29, 2017 The only thing I can say to that is - so is Buster's I drove his car the other day and 1 on the HU is LOUD I think it bursts ear drums at about 4 I mentioned it to Buster - he said I'm just too old (I'm younger than him!) I have no idea if you can reduce the gain unless your HU has the option to do so? 1 Quote Link to comment Share on other sites More sharing options...
scobie140 Posted March 29, 2017 Share Posted March 29, 2017 I found this aswel but before i did it it was really quiet. Best solution is to listen to songs off a memory stick etc so at least your deafened by your choice of music and not guff on the radio like one direction Quote Link to comment Share on other sites More sharing options...
MDMetal Posted March 29, 2017 Author Share Posted March 29, 2017 With just the HU I found the volume was perhaps 50% too low vs the stock unit, but then only 1/2 the speakers were producing an output. As I said the HU only has front phono connections so I had to do the mod anyways I'm just wondering what the best solution is, it's really not practical to have the volume so loud early on. I guess either an app that modifies the volume range on the HU or find if the amp itself has some gain control, failing that a preamp volume control just to drop the input voltage.

MDMetal Posted March 29, 2017 Author Share Posted March 29, 2017 Attenuators are what I need it seems, I would be able to lower the input to the amp and effectively pick a range between "maxiumum buster" (as I'm calling it) and zero so a nice fix for anyone who wants something in the middle 1 Quote Link to comment Share on other sites More sharing options...

D350z Posted April 4, 2018 Share Posted April 4, 2018 I have the same problem with the hissing sound even with the volume turned down. I thought it might be the bose auto gain system that compensates for road noise etc but even when stationary it is really bad. With the speakers up it gets drowned out but sometimes I just want to listen to spoken voice and it is really annoying. Has anyone swapped out the bose amp fro an after market one with less gain and no funny gain system? Quote Link to comment Share on other sites More sharing options...
CLASSIX Posted July 30, 2018 Share Posted July 30, 2018 The Bose (CLARION) amps run at 1ohms not 2 4 or 8, you need a pac-rom to put new headunit in correctly, the buster method just overdrives the amps on full chat and cant be adjusted. also the buster mod is pretty much the same as using an iso lead for the non amplified set up in a Z. there are some good how too's elsewhere on the forum to guide anyone when fitting new HU Quote Link to comment Share on other sites More sharing options...
