Re: Sound System Upgrade...Wow! What a difference.
 

Oh s&$t...you had to ask. I can't find my paperwork as I did the work last Fall and misplaced it, but you can look on Zip's web site and get the prices. There, obviously, was no labor charge as I did it all myself.http://www.zip-corvette.com/GroupDet...er+Amplifiers&

Thanks

Re: Sound System Upgrade...Wow! What a difference.
 

I don't think there was any sound cancellation built into the system. Despite all the negatives reagding Bose amp/speaker set up, considering the size and weight, quality and quantity of sound is hard to beat due to carefully sized and tuned boxed enclosure Bose designed to work with their speakers. However, if you want to hear the low frequency a subwoofer addition is necessary.
When I replaced the head unit with a Pioneer AVIC Z140 I was amazed at quality of sound in HD FM, CD and ability to use IPOD/IPHONE, DVD and run navigation. Head unit quality and quality of HD FM improvements made in the last 20 years is phenomenal despite my hearing being not as sharp as it use to be.

During the installation on my 95, I tried a sub...a Bazooka driven by a Rockford 300W amp.

It made little difference. I decided the new Bose speaker assemblies were all I needed so I returned the Bazooka and the amp for a refund.

Re: Sound System Upgrade...Wow! What a difference.
 

Bazookas don't really do much. So, I built this enclosure about 3 years ago and hooked up an old Alpine I had. New "low profile" sub allowed me to keep the sub box relatively small.

This will be a nice hijacking of this tread....... Your enclosure
blends in nicely and looks to have plenty of clearance for the top to fit in. Did you check the cabinet for resonance? The reason I ask is the small size usually leads to problems like that. If so you can tune it out with a "port".
A port is a 2in (or so) diameter hole with a tube (ABS plastic will do) into the hole. The depth of the inserted tube will tune out the resonance.
In this case the resonance would be up close to the top of the low range because of the small box size.
To find resonance you can use a leveled tone audio source then sweep through down to 20Hz or so. Where ever the tone seems to get louder is your box resonance. Then use the tube to tune it out.
Alternatively...... using a graphic equalizer (in the tuner) you could put a notch at the resonance location.

But then if it sounds good to you as it.... it's all good.

The last box I built was for an Explorer. It was large enough where the resonance was down low so I didn't care.

Trivia: next time in the shower find the resonance of the shower booth by creating a tone and slowly lower it until you hit it. Almost all showers will have a resonance. My kids use to day "Dad you have a problem". I'd say " oh well". :-D

Nice enclosure !!!

Re: Sound System Upgrade...Wow! What a difference.
 

It sounds good but I will run a test CD and see. Pioneer recommends .35 to .85 cu ft of sealed enclosure for these low profile 10" sub and mine came in at around .8 if I remember correct.

I installed a Pioneer 3300 DVH with DVD screen. It is a Double Din unit. It fit right in the original bezel. I had to nibble out a plastic locating pin that support the original Bose unit. Pioneer is a fantastic unit. I pulled the seats to clean the carpet, and ran new wiring to all new speakers. It has back up camera, computer inputs and outputs, IPOD compatible. Unit costs $325.00 plus the speakers. I bought many Bose amps, and drove the car for years with NO radio, as there appeared to be nothing that would fit. Professionals had no idea what would fit either.

Hib - Thanks for your efforts, and the write-up.
The original system has been a thorn in the a** of ZR-1'ers for decades.

Re: Sound System Upgrade...Wow! What a difference.
 

Like Bob, I have the Pioneer DVD 3300 BT unit, but I chose to stick with the Bose speakers that I had recently sent through Bose's refurbishment service. (note it was the absolute trail of tears to install the adapter wiring harness)

A little file work on the new radio head made it fit the console bezel perfectly, the colors are adjustable to match the orange factory lighting and the sound is fantastic.

One thing to look for on new head units is the 4V output on the preamp, many units are now only 2V.
