Speaker replacement
I wanted to see if you guys had some ideas on speaker replacement. I have the crappy bose system right now. I plan on keeping the Nav, I just want to change out all four speakers and the (Twiddlers) and install a better amp Not trying to spend thousands of dollars. Just get a nice upgrade over the bose system.

There are a lot of helpful and expert members/vendors that frequent that section.
I learned a lot over there and replaced my whole system.
I kept my factory nav and added pre-amp out RCA cables that connect to aftermarket amps. One amp for the doors, one for the sub in the rear.
Pre-amp harness plug and play in the factory harness and HU.

Polk components with adapter plates for the doors.

Amps inside Vettbin behind the seats.


12" sub in the back.

Also disconnected center dash speaker. I left the rear speakers alone. They are still connected to the factory amp.
BTW, I learned how to do everything from reading THIS thread.

Man, I saved myself a lot of time, effort, and money, by accepting the Bose system, as, "good enough for me."
The frequency response, and dynamic range of the Bose system, would have been unacceptable to me even 20 years ago, by the standards of 1995.
However, now,....it's good enough. Priorities change I guess. Nice job!

I did an acoustic analysis and found the system to have a quite flat and extended frequency response.
I think the major short-comings are the lack of separate tweeters as the mid-high "twiddlers" lack detail and crispness, and expecting the door structure to support the 10" woofer/subs is asking a lot.
IMHO the overall installation is rather clever with the woofer's amp integrated with the speaker and given the rather severe space limitations and acoustic anomalies present in the Vette's interior (especially the vert) the OEM system does a decent job juggling the compromises.
The one saving grace is that the head unit's output is flat with all the unique Bose EQ/tweaks being performed in the amps. This makes the amp/speaker upgrade a little easier.
Adding acoustic treatment (Dynamat for example) helps immensely, as does stiffening the doors/panels.

You could have said, I tried Polk speakers once and didn't like them.
Or, I had Polk xxx.x speakers, and they performed poorly, so I don't use Polk anymore.
Instead you make this broad statement, "Polk is pure garbage".
I reacted as I did, because Polk makes some very good speakers, and enjoys a fine reputation in the speaker industry.
I've been building home audio systems since the late 60s, and home theater systems since the mid 90s.
I've used Altec Lansing, University, Bose, JBL, Boston Acoustics, Martin Logan, Infinity, and others.
However, I've achieved some of my favorite sounds with Polk systems.
In fact my current home theater system, is all Polk, except for the Sub-Woofer which is Klipsch.
You used a very broad brush there Billy. Everyone's perception of what constitutes good sound is different.
That's why there's so many different speakers to choose from.
