Thanks, I plan to do the dash speaker replacement in the next few days. My plan is to use the new speaker "as is" and see how that sounds. I don't think I am willing to take on the replacement of the front door speakers myself, but may have an audio shop do that if needed. I would love to think that the overall sound is improved enough with the addition on the new dash speaker to negate that action, but that remains to be seen / heard.
You know what? I forgot to test it with no bass blocker added at all. I was thinking it was to be a test of the two different blockers. Sorry about that. It should sound fine with none, but I'd expect it to be a little cleaner with the lesser of the blocker options. Looking forward to seeing your impressions. Hopefully I'm not just imagining the differences.
