My CPO 2004 allroad 4.2 came with Bose premium sound. I like the highs and mid well enough but the bass only seems adequate for pop music. It's loud and punchy down to a certain frequency, then it disappears.
I listen to all kinds of music, including classical and jazz, and would like to improve the low end without rebuilding the entire system.
My installer is recommending adding a Bazooka BTA 8200 powered sub tube (200 watts, 8 inch driver). I read the tech post so I know we'll be able to run it off the Bose system, but I'm wondering whether anyone who has added a Bazooka tube to a system like mine can comment on the results.
Thanks.

...it really helps...

I thought that was only for certain years

Not possible... Wrong year for that, He has an '04 - hidden Eq '01-

or just the Bose/ Symphony II??

The Bose is just VAG setting for the headunit plus some extra amplification and sub.

So yes on all '04's the hidden EQ setting is not present.

uber_ar

It is.... 01 and earlier have it.

...that's to blame for the weak bass. When I listen to CDs or an iPod through cassette adapter the bass is superb. XM must compress the signal a lot and/or cut off the bottom end for digital transmission.
Canceled the Bazooka installation, charged my iPod and popped a couple CDs in. It's all good!

BTW: My system does not have the hidden EQ, but the standard EQ works quite well.
