From my own perception, the Bose system does indeed sound better than the Clarion system. That said, though reasonably better than my BA wagon's crap, I consider both versions to be shite anyway.

However, as I outlined in my write up on upgrading one's sound system in a V36, for the sake of making the installation an easier process, it is better to get a vehicle with the Bose system so that you can minimise rewiring in the vehicle if you decide to run split component speakers front and rear, unless you aim to push huge amounts of power, that is.

The Bose head unit is actually worse than the Clarion if you put an aftermarket amp into the car. The amount of crap it outputs is amazing. White noise galore. Had to install a processor to get rid of all the crap

What kind of processor? Neither system is terribly clean but by design, the Bose should be cleaner as it feeds the OEM amp in the boot with a balanced line level signal. With a good DSP, it should be able to take advantage of that balanced feed and therefore significantly reduce any analogue issues. If you tried to just feed those line level signals straight into an aftermarket amp without any balanced to unbalanced matching transformers at least, if not a well-designed DSP, then I'm not surprised you got the noise.

Anyway, for my ears, all car audio systems ideally need some kind of DSP. Just a couple of tone and bass controls doesn't cut the mustard. Not all speakers are created equal, nor are amps, nor are the sources. Only when you have that detailed level of control will you squeeze the most out of it all and probably end up running it cleaner which means less abuse of your speakers.

Mine has a very slight DC offset, which gives a little white noise as a consequence. I could design a line driver which would process the DC offset out of the speaker leads but it's only noticeable at low volumes and I barely run mine below moderate.

i have had cars with both and bose is much cleaner at higher volume levels, its much clearer overall and better bass too. i would recommend wait for a Bose model to come up if u can,

We basically tried taking signals anywhere from the head unit to the factory amp in hopes to be able to get a decent signal. There wasn't much luck with powering a good set of speakers and subs. So we had to use aftermarket amps. In which we were met with pretty bad crappy signals. So now I have a bit ten installed. Boss head unit has own eq added onto the signal. Any signal you take coming from the head unit will already have the crappy eq added onto it. The DPS strips the signal down and gives the amp a clean signal to play with.

I'm not a big fan of how Bose has implemented the system and the speakers are pretty meh IMO. If you're gonna pay extra $$ for the Bose system, it may be cheaper or more worthwhile just getting the non Bose and put in aftermarket amps, speakers and subs.

Yeah Bose is cleaner n clearer due to the "better" amp and speakers over the non Bose.

Here's the thing though. You're feeding a balanced audio signal into an amp which likely only took unbalanced audio and at probably vastly different impedances too. If not properly matched, you will get the hiss/white noise you referred to. That has nothing to do with how Bose manipulate the audio through their built-in DSP. Sometimes you can get away with grounding the cold phase of a balanced signal directly but sometimes, if the impedance is way off, you need to use transformers (baluns) or active matching, which is what you've essentially achieved by using the Audison Bit.One, as I believe that also supports balanced and unbalanced inputs.

But then the EQ'ing and delays that they introduce to suit their speakers, I agree, you then need to use your own DSP to counteract all that so that you can flavour it to the aftermarket speakers you've decided on, as they'll have different characteristics. The Audison Bit.One is a pretty good unit, so you definitely did well there but that's the nature of adapting things that weren't necessarily made to be adapted.

Again, in my opinion, to do the sound right, all audio systems (home, professional and mobile) require DSPs to squeeze out the most performance out of your rig. I can't imagine not using a DSP in any scenario, personally.

Hi, I had the bose set up in mine and it was shit!  Out of all the mods I've done ripping the factory bose HU/sat nav, amp and all speakers out and replacing with aftermarket was the best mod!

    • You can’t see much on the other side as the lcd is there I don’t think it’s the same as the m33 beside it as the markings on top is not the same was hoping someone had a good quality photo or if they just happened to have the unit in hand, quickly take the cover off and take a photo to clearly show the marking on top to identify the diode   the unit is currently with an electronics repair shop so I can’t take another photo at the moment hopefully they are smart enough to know if it’s a zener diode or not
    • I'd be very surprised if you can buy new OEM mats. But if you can, I want some too!  Do you have links to the variations you found? Also, where are you located? I found that Nengun is happy to list items to purchase but when you do buy them you'll get an email that it's actually discontinued. As far as I know the variations in floor mats are different colour schemes as well as automatic and manual having a slightly different shape. The automatic ones fit into a manual car without issues, but I think you'd have trouble fitting the other way around. I have photos that show the shape difference if you care. FWIW I bought sets of used floor mats in decent condition at yahoo auctions.
    • Hi 🙋‍♂️. Just bought my Unicorn but the interior need some minor work so it would match my expectations ;). I noticed it is hard to get used oem floor mats in good condition so i started to dig if there's any chance to buy set of new ones. I found two websites - nengun and amayama and it looks like one can still buy factory new floor mats in Japan, but thers a small issue. Some mats (i assume genuine, oem ones) are marked as G4900 and these are "discontinued". The ones you can buy are marked as G4911 but i have no idea if these are also oem, made by other producer or some lower quality replacements that looks entirely different. Can anyone help? 😃  P.s. there is also some strange indication - 0V005, 0V015 and 0V505. Any idea what does it mean? Would appreciate any help with this 🙏
    • Hi, Marek here 🙋‍♂️. I finally fulfilled my longtime dream - recently bought Stagea and now waiting for it to arrive in Poland. There's only few of these in my country, and one of the owners  recommended mi this forum as a source of all the info i'd need since now i own one  so here i am.  
    • Version 1 aluminium airbox is.......not acceptable No pics as I "didn't like the look.....alot" Even after all my "CAD", and measurements, the leg near the fusebox just didn't sit right as it ended up about 10mm long and made the angle of the dangle look wrong, the height was a little short as well, meh, I wasn't that confident that Version 1 was going to be an instant winner I might give Version 2 another go, there's plenty of aluminium at work, but, after having in on and off a few times, and laying in the old OEM airbox without the new pod filter and MAF, there may be an option to modify the OEM air box and still use the Autoexe front cover and filter.... maybe This >  Needs to fit in here, but using the panel, and not the pod, the MAF will need to fit in the airbox though> I'm thinking as the old OEM box and Autoexe cover that is sitting in the shed is just sitting around doing nothing, and they are relatively abundant and cheap to replace if I mess it up and need another, it may well fit with some modifications to how the Autoexe brackets mounts to the rad support, and some dremiling to move it get in there, should give me some more room for activities, as I don't want to move the MAF and affect the tune Sealing the hole it requires to stick it in the air box is simple, a tight fit and some pinch weld will seal it up tight  I am calling this a later problem though
