92 z28 Amp, subwoofer and speakers with OEM head unit
Hello, guys is my first time to post in the electronics or car audio section.
I have my 92 z28 and when I bought it came with a old school Kicker box that never was installed. I'm debating in my mind if I install it or not. I bought the car from the first owner with 29471 miles so head unis have to stay in it place. What is the best route to make a good set up for my car using the kicker box with new subs,speakers and amp keeping my factory head unit? The goal is a clean and crisp sound with some good bass. I'm a heavy metal fan.🤟🏻

If you're adverse to changing the head unit, chances are better than average that you're also adverse to splicing and hacking the wiring. In which case, tapping out for a line level converter is probably out of the question. Regardless, the factory headunit is really going to show it's weakness when you start amplifying the signal and trying to play it at higher volume. At best it'll sound "uhh, ok" at worst it'll sound like total ***. Been there, done that, ripped it out and put in an aftermarket head unit.
I've got a bass tube in my Formula. I've got a line out converter in my junk box, and the factory head unit in the dash, currently the tube isn't connected to the headunit, if that gives you an idea how poorly I think it works out. And that's just a little bass.

Generally, yes. Upgrading all the stock speakers is usually a decent upgrade in sound quality. You might want to add a bass blocking cap inline to the front speakers as a filter, otherwise it's pretty easy to kill the typical 4x6 or 3.5" dash speaker. The exception is if you're using an aftermarket speaker with a built in crossover/filter/whatever. The next thing you'll run into is the stock headunit distorting at moderate to higher volumes.

If i decide just upgrade the factory speakers with the factory head unit, you think it will sound better?
Factory Delco head unit was made to push 2 4-OHM (rear) and 2 10-OHM (front) speakers. You can see a bench test video here to see what happens when 4 4-OHM speakers are connected to a factory Delco head unit.
Speakers used: 4 factory Delco( 2-4OHM and 2 10OHM) ; then 4 aftermarket Pioneer (4-OHM); then a combination of 2-&-2 ; then reverse of the 2-&-2.
1) When just 2 4 OHM speakers were matched with 2 factory speakers (Front-Pioneer/ Rear Delco or Front Delco and Rear Pioneer) The head unit continues to produce sound at max volume.
2) When all 4 Delco speakers are used the Head Unit continues to produce sound at MAX volume.
3) When all 4 aftermarket 4OHM speakers are used the Delco Head Unit "quits' before reaching full volume. ( varies depending on how much the BASS and TREBLE are adjusted
** At 1 point I called the aftermarket speakers "4-AMP",... I meant 4 OHM
** Battery charger was NOT connected at any time of test.
http://berlinetta.info/video/4OHM.mov
I'm sure that a battery that's in regular use might push enough power to keep the Head Unit to keep working all the way to full volume,... but there was really not a noticeable of a drop in the voltage during this video. This little exorcise is not an attempt to declare ANYTHING !!! It's simply an attempt to show that using 4OHM speakers puts a lot more stress on a Delco Head Unit than using speakers that the Head Unit was designed for.

Happens to the best of us.
Stock are 4x6s. Even some of the aftermarket 4x6s can be a tight fit in some cases. 3.5" round speakers with an adapter plate generally fit better and sound better than an oval speaker anyway.

forget the dash speakers-you will get far better sound if you install 6 or 6.5" woofers lower door and tweeters higher up on the door.Factory style Delco head unit can work very well with great sound if you can install pre-amp outputs to hook to amp or use Delco-Bose head sending output to amps.
