Default What is the Ultra Base code for the Bose radio? Going to dealership tomarrow...

Does it really make the Base sound better? Does it void the warrenty of the radio or anything associated?

Default according to my dealer most people that they change the stereo coding for end up changing back..

we don't have a sub, so you're never going to get that 'sub' feeling... i think the bose set up sounds great, and i've heard a LOT of different systems. *shrug*

some people are never happy though.

Default I have a very different opinion than what you posted...

I did the recode of the Concert radio to non Bose which added for treble and bass to +6...the two speakers in the rear indeed act as 'sub woofers' and sound is excellent...anyone who has been on my car and listened to YELO (wanna stretch your system to limits of high and low end...pop that CD in..) and I would not change back to the standard setup. I now control the tonality of the system and adjust for each CD according...from classical to jazz to the Miami sound all are improved with the non Bose set up. Is it = to $2000 aftermarket with 12" sub drivers...no...but close enough for my ears.

Default Re: I had my Bose recoded to non-Bose at FH2O..

It's a definite improvement. With the Bose mode on, there are some of my classical music CD's that will come out as silence when it's actually a solo instrument playing in a low key. It's very annoying. Even with the volume cranked up I still hear nothing (e.g., Beethoven's 9th, 3rd movement with the tuba and viola solo's). It's no where close to my home audio but at least I can hear it. Apparently there's a dynamic range that the Bose mode will play that range is narrower than the non-Bose concert mode.

Default For some reason, my bose already had the ability for treble and base to go to +6 and -6.

I love it. Just as Michael said, it gives you the ability to adjust accordingly for each CD.

BTW, Thanks again for your help with the Forge install, Michael!

Default I'm still not sure if I'm staying "unBosed"

There is a big difference between coupes and roadsters because the roadster does have a subwoofer. I definately feel that a mega-bass roadster sound better than a mega-bass coupe.

Some recordings do sound great but others suffer a bit from a muddy low end. I find myself adjusting tone levels much more often than I used to.

I will probably go back soon enough because I still don't have the crisp low end I'm looking for and my fun money is going towards Bilsteins, not a sub woofer/amp setup.
