Over the last month, I've completely redone my stereo. Here is the deal:

Stock bose HU

Pre outs tapped at the bose amp to a jbl cs60.4.

system rewired to bypass bose amp completely.

jbl amp powers everything.

bandpass box with 2 8" woofers

rear door speakers disconnected

front kickpanel speakers replaced with jbl 5.25"

tweeters unchanged

When wiring the front speakers to the amp, I used the oem harness so that the tweeters are used.

Problem is, on some songs, the vocals sound distant and quiet. Especially on U2's Achtung Baby album.

On others, no noticeable fall off.

Any suggestions on how I can fix this, or compensate for it?

Thanks,

if it were a phase reversal it would show up. i haven't taken the time to calculate whether this could actually happen in your car but all other fixes are way more complicated and expensive. good luck, or, you could get a new favorite album

and just use an inline capacitor to filter the high frequencies. There is no point upgrading the front speakers and leaving the stock tweeters in, you might as well not have bothered.

wanted to get my interior put back together.

Swapping out tweeters at this point should take about 15 minutes.

getting proper components that are matched. Are the JBL's you have co-axial?
If so then disconnect the tweeter on them as at the moment they'll be stealing power from the proper tweeters.

The jbls are 2 ohm, and I'm not convinced the tweeters are. Some on the b5 forum have run tests and they indicate they might be closer to 4 ohm.

Guitars and drums sound righteous, just on some songs, the vocals are way too quiet.

I need to get a true 2 ohm tweeter, I believe.

And, the reason I got them was a guy local to me hear is a rep so I basically got them brand new for hardly any $.

The Bose upgrade uses the same Nokia tweeters as non-Bose.
Running tweeters on the JBL's firing into your shins and the stock tweeters together will sound dreadful as the signal will be shared.

JMS-Four

not my specialty, as I have deftly demonstrated.

Thanks for your advice and info.

replacing the tweeter may not help if its set to not play those missing frequencies

Yes as an interim solution, still highly recommend proper matched components
