Any advice on car audio?


I have an older Saab and am thinking about investing in a new audio system since this one does not have a cd player\, or an amp.
Is it possible to get good sound in a car? Any advice on how do to so without spending a ton of money, money that i could put into my home system?

I second Golden_ears on most points.My introduction to music
reproduction began in car audio.Started in '78 and retired few years ago.Done a few great set-ups.The better sounding rigs really are ground up projects,choosing a good vehicle
picking out equipment,improving electrical system from stock
and interiors as well.In the end you have issues to which only more "stuff" in the signal path helps.The good news is
the entry level gear is a bargain now(If you don't get bitten by mobile theater bugs)I alway advise start simple.
Remember thieves abound and loud rigs advertise best.

Start with your front stage.Pick out a head unit with good ergonomics(remember you may not be only driver on the road with electronic distractions)I dig units w/steering wheel remotes,several brands have that option or hanheld ones for
relatively cheap.Mosfet amplified head units are now very common and start at under 2 bills includes digital domain parametric equalization.Go for efficient speakers
well placed 2way seperates in lower kick panel pods seem to work best.Upgrade paths can be more power.Tweeters can be added up higher in dash and powered by headunit.Infinity makes nice very flexible efficient powered sub.Thing about
autosound you should keep in mind is that cars are noisy enviroment(70+db background noise,best demo is sitting in a parking lot or the stores display)They have complex electrical systems and many digital sytems now,and boundary effects,oh my.
So start small clean efficient.Place your speakers well.
Philjolet, the only single driver units I am aware of have those paper whizzer cones in them. Typically they are on the low end, price wise and I am sure they aren't intended as anything but a cheap, full range speaker with limited ability. They do make good coaxial speakers but separates are really the only way to go. Getting the tweeter placement higher up in the car and properly positioned is the only way to get anything approaching stereo separation. Anything less is just so much noise coming from your door panels.
I was into car audio for quite some time and built a number of systems (separates & subs) for my cars including a 1984 VW GTI, a 1988 Toyota 4Runner, a 1988 Porsche 911 and a 1994 SeaRay 180BR...yes...a boat...then I got into home audio and never looked back...now I wish I hadn't wasted so many $$$ on car audio that was either stolen or sold with the vehicle...sure it sounds nice, but I find that the less I listen to music in my car now (with the exception of road trips)...the more I appreciate my music when I get home. Just my 2c

Hi, I'm going to throw my little bit of my reality here. I've been doing systems for my car for over 25 years, and still enjoy it quite a bit. I started my career performing car installations, though I have moved on to other technologies. And though I'll admit that I have scaled back my systems, I still enjoy upgrading the stock system in my car. It is car audio that got me into the audiophile bug. For it was these systems that I started noticing more elements in the music, I'd be driving along and notice that I had never heard something in a song before. I was missing stuff. I had a decent image, full sound, and details appeared before and around me. I learned through this experience to begin to look for more from my home system.

I'll also add, as Ellery911 mentioned, I lived in my car, hours each day, two-hours minimum, typically more. So having a better system in my car was a requirement for me. I am now listening more to home system and less to my car. Though the car still sounds good, the house sounds great.

Is a car a perfect audiophile experience? No way. Can you get good to excellent sound, you bet! It all depends on what you want and how much you want to spend. And you are going to get some very polarized attitudes about sound in a car. I believe even more so as compared to home audio.

I've owned several Saab models from a 99, 900, and 93, sedans, hatches, and convertible, each has it's own issues (my 99 was wonderful and unique at the time).

A couple fo things I'd like to ask:

1. What do you define as "good sound"? What are your expectations for the car?

2. You mentioned that you have an older Saab, what year? Model? And style (2 door, 4 door, hatch, convertible). There are basic installation issues and concerns that need to be addressed with each.

3. What is your budget? Good sound, depending on your definition, can be had relatively inexpensively?

4. What equipment do you have and/or like now? Knowing your tastes can nail a system a lot better.

Yes, you can do a lot of things to tweak a car to help improve the output, imaging, and environment. And there are a lot of different ideas and methods achieve this, but that's it, tweaking. As mentioned in previous posts, adding sound dampening materials (such as dynamat or dexdamp) can help lower the noise floor within the car. Especially the squeeks and rattles within your car. It'll also add a lot of weight to the car (I happen to have a box next to me right now that I was going to use for a previous installation, it covers 20 square feet and weighs 20-30 lbs, it's heavy, it'll be like adding an extra 1-2 people to your car, depending on the extent of the install, this will affect handling, ride, economy, and load ratings). If you've ever heard a Mercedes door shut, compared to an inexpensive car, there is a more solid, deep shut with the Mercedes. That is sound dampening and that is what it will do for you.

Speaker placement is also a major topic. Unlike home systems where speakers can be easily adjusted to obtain optimal sound, the car really limits this placement. A couple of things to note about placement. Car speakers, unlike home speakers, are typically designed to be very, very directional. Because there are so many hard surfaces for the sound to bounce, this helps with imaging in a car. And because multiple mounting locations can be used, tweeters up high, mids & woofers down lower, there can be other acoustical issues that occur, time relationships, acoustic separation. But by placing speakers up high, the image and soundstage will rise as well.

Also the installation location will affect the speaker. Dash speakers tend to lose bass output versus door or shelf installations (a dash does not make a good enclosure, a trunk does). And another issue is cabin gain, a cars natural environment will boost low frequencies (when everything else is done right). You can also play with speaker wiring polarity adjust the perceived imaging.

I'd start by getting some good solid speakers (separates or very high quality coaxes - and this can be separates mounted in a coax-type configuration), some dedicated amplification, and a decent front end, and you'll be surprised at the sound in the car. I have a good head unit, Clarion, a Soundstream amp, and A/D/S/ component speakers. I don't have a sub, I dropped that a couple of years ago. A cars cabin provides gain in the low-end, and speakers with decent output in the low-end will have some gain added naturally by the car. Over time I have found this setup to be more musical, though with less impact and extreme extension. And when a good song comes on, it easily overcomes any of the road noise in the car. Though I should mention that the whole car audio world changes with a convertible and/or all your windows open - then you would probably want a sub.

I've had one stereo ripped off, back in the 80's, I haven't had an issue since. It all depends were you go with the car. I don't believe you can prevent it, and this is why you have insurance (keep receipts and take pictures). A detachable face front end helps, especially if you take the faceplate with you. But many people don't, at most they remove it and leave it in the car (glovebox or door pocket). Some companies will hide the faceplate, others will use coded keys for security, all can be bypassed in one way or another (sometimes the factory will need to do it). Car alarms help as well. I believe the car itself is the more primary object of theft nowadays, anyway.

Hope this helps, Todd
