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

[Schrade]

Doesn't the factory system play ambient noise in its' acoustic inverse?

Is anything better than that?

Any replacement in my vehicles will have to have an SD / MMC card input...

Sorry, "Schrade", I'm not an engineer in acoustics or electronics so I don't understand the term "acoustic inverse".

Is anything better than that?

No doubt there are a ton of higher-end aftermarket receivers you could install but, so far, the only ones available with Zip Products' "plug-and-play" adapter hardware are the Pioneer I used and a Kenwood unit.

[Schrade]

No need to apologize at all!

Depending on what the cost is of servicing the factory unit, i just wonder if that wouldn't be better...

[scottfab]

Hib, what was the overall cost and per unit costs?
What are the spec (or a link) to the Zip amps?

A wildly detailed set of articles for sure.
Well done.

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.

Are you referring to "Sound Cancellation Technology"?

I dont think that technology was included in the C4 Corvette.
There was SCV or "Speed Compensated Volume", the faster you drive, the higher the volume becomes. My 1997 GMC pickup has this. The stereo head unit receives a speed signal from the PCM. If I'm on ice and nail the throttle and spin teh tires really fast, all of a sudden the volume of the stereo spikes momentarily. Kinda shocked me the 1st time this happened.

Later Cadillac cars came with a technology that sensed when a window was rolled down, and increased volume to compensate. But I dont know if "Sound Cancellation Tech" was included.

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.

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".
