I own a 2003.5 6MT and I'm disappointed with the lack of highs in the stock premium system. Any suggestions on how to improve it? Replace the speakers, add an EQ, or replace the amp? Thanks!

All depends on how much ur willing to spend, as to what you can do. Give us a price range for more info.[]

who'd want to put the radio too loud anyway - you'll hide that beautiful exhaust note .

But seriously, it all depends on how much $$ you willing to part with. From other posts, it seems pretty clear that direct speaker replacements will not work - you'll get less sound and less sound quality - Bose amps and speakers are desinged for each other and nothing else.

Good luck - get back to us with some more info on what you want and $$$.

I'd really like to keep the stock head unit. I just want to up the highs a little for some crispness. I haven't thought of a price range, but something reasonable...maybe 5 bills max.

Bose speakers roll off at about 15kHz, which is probably the problem you're hearing (or aren't as the case may be). The "audible range" is between 20Hz and 20kHz. You won't get any notes above that frequency from these speakers no matter what.

My suggestion would be to replace the speakers and the amp.

Hi:

On the various G35 boards it is remarked that “Bose Blows”, the most common complaint being that it lacks solid base and sparkling treble. I am not a car audofile junkie but I did find that the upgraded Bose system lacked highs. This is a way to correct this problem by re-recording your CD’s. It will only work on CD’s, not on your car radio or satellite.

Hook your pre-amp out to your computers audio input. (You can get the connector cable at Radio Shack.) Set the Base and Treble higher (you can also turn on Loudness) and using your computer software, record your CD tracks independently. They will be recorded as .wav files. Do not rip to MP3!!! If you have a Dynamic Expander, turn it on, (except for classical). With a dynamic expander, you may need to reduce the base and treble levels into the minus area. Using a Dynamic Expander (if you have one) gives the best results to any up beat music! (All of this works best if you have a good sound card in your computer. On board audio may not give good results. I have been please with the result from my Sound Blaster Live and will soon upgrade to an Audigy 2 for 24 bit recording. Do NOT buy an Audigy 2 if you are running any version of Win 98!!!!!

Because everybody’s stereo and computer are a bit different and due to differences in personal taste, first experiment with only one CD track that you want to enhance the sound on. Pick a track that has strong, low bass tones and good treble. After recording it to your hard drive as above, burn it to a CD. Then put the CD in your car player and see if you need to revise the record settings on your Hi Fi. Once you have the Hi Fi pre-amp settings where you want them, you can record and burn more of your CD library.

This technique can also be used to record and enhance FM music for your own personal use.

When burning your enhanced music tracks to CD, be sure to record at a speed of 16 X or less. This should give a better CD burn for more sound clarity and playback.

I have done the above and the improvement in sound quality in my G35 is very significant!
And I can save lots of money because I don’t need to upgrade my G35's sound system.

Good Luck

That's not an improvement. It's the same philosophy behind Bose speakers in the first place. That's actually a degredation in sound quality. You've artificially increased the gain on certain frequencies which is a loss of precision, not an improvement. This doesn't change the fact that the Bose speakers are simply not capable of producing the full music spectrum, and instead focus on artificially punctuated bands around 14kHz and 200Hz.
