If you are looking for more details, kindly visit Dingpei.

Both of my tweeters are blown (sound fuzzy when subjected to even the slightest amount of bass) and my two rears are nearing the end of their useful life.

I was just wondering what I should know before getting some new speakers in my automobile.

I am a huge rookie when it comes to this. I also don't want anything too drastic, just some decent speakers. If it helps, there's an aftermarket radio unit in there (not sure what you call it, its a CD player, has an aux in, the volume knob etc) that a PO put in. I'm fine with everything it has to offer, just want new speakers.

'83 533i

thanks!

...what you should know? Pretty vague there. I'd start with the difference between tweeters (by your sideview mirrors) and mids, at your feet.

Tweeters don't handle even the "slightest bit" of bass-- they are made for highs only and are seperated from your mids with a crossover or high pass filter. (And unless you need the tweets to enjoy your Dave Matthews band, I would just disconnect them if they are making odd noise.)

Speaking frankly, a rookie could learn a WHOLE lot by reading what has already been said on the subject by doing a search. Find the button under the logo, above. Or go to the local car audio guy and pay for new speakers.

Otherwise, get some 5 1/4" speakers and pop them in. Last edited by nnarth212 on Sep 30, 6:03 PM, edited 2 times in total.

In your reading, you'll probably come across the problem with new head units and a chassis grounded speaker system. Check your speakers to see how they're wired.

The PO may have improperly wired up the speakers with the aftermarket radio. There is a grounding issue with the factory wiring and aftermarket radios. Do a search here and you can read all about it. Also, if you need speakers and have mild requirements, I recommend Alpine for your fronts (by your feet) And Alpine or JBL for the rear speakers. Both are readily available from Best Buy.

Running new speaker wire helps a lot. The OP will have to run 4x6 speakers if he wishes to keep the stock look.

Indeed. In a previous life, I spent 10+ years in the professional radio communications business, mostly municipalities, police, fire, dispatch centers, but we dabbled in consumer radio as well. I used to be brilliant....not sure what happened.

Unrelated, are the fog's interchangeable, L and R?....cause if they are, I'll buy your fog right now, and just look for another one as well.

Maui is calling you....

If you don't want to make kick panels for the front, you will need to stay with a 4x6 plate as Chris mentioned. However, fitting a set of 5.25" separates makes a huge difference in sound quality. Also, as mentioned, it's really important to rewire the car to get rid of the common ground system. If you are interested in running 5.25" speakers up front, search for my stereo install thread to see my adapter panels.

This may sound silly, but is it too difficult to install 6 inch splits at the front kicker panel using adapters, or do you think they may be a bit big? Also do you know if you can mount aftermarket tweeters inside the stock position tweeters case?
Also, do you know anything about In car DVD players? I'm not sure if the single DIN motorised units will have enough clearance for proper viewing (as the e28 dash part above may protrude). Do you know?

Cheers

Mounting 6" drivers is probably possible, but it's gonna be a stretch. You may have to make a plate that's a little more elaborate than what I did to accommodate them. The nice thing about the ones I used was that the mounting depth was fairly shallow, allowing the magnet and part of the basket to drop into the stock speaker opening. The coloring on the kick panels is actually a really nice match to the llama interior, but the lighting makes it seem very different.


As for mounting tweeters in the stock pods, that is exactly what I did.





Unfortunately, I have no idea regarding the DVD player.

Wow, thanks heaps for the photos. Your right, its probably a better idea to go with 5.25inch also due to mounting depth. I'm going to try make some kick panels just like yours. I couldnt find much info on them, do you know if any threads go through their dimensions?

Since the OP has an '83 533 he does NOT have the premium audio setup, so he does NOT have the 4" mid in the kicks with the poly dome tweeter up by the mirrors.

The early cars had a pretty crap 4x6 speaker in the kick with no tweeter by the mirror.

If you simply want to replace the kick panel speaker thats easy enough. There are a number of 4x6 coaxial speakers that will fit that space and fit under the grills (you may have to put small spacers between the speaker and the grill because of the tweeter sticking out-steel washers work fine).

If the previous owner did not replace the speaker wire thats a very nice, simple DIY project that you can easily accomplish in a Saturday afternoon, and it will dramatically increase the sound quality of your system.

How to Build an Amazing Car Audio System

Listening to music while you drive may be one of your favorite activities. You may want to upgrade your outdated radio to have a better driving experience. Car electronics are an important part of cars today because of the many ways you can listen to music in your car. So, how do you go about building an amazing car audio system?

According to learn.sonicelectronix.com, the first car stereo was introduced in and it only played AM radio. Today, you can upgrade your car stereo with any new car electronics you want to give your car the newest and best features there are. Definitely more than just AM radio.

Find Out What You Need

Before you tear apart your current car sound system, figure out what you need. What upgrades do you want to make? Write a list of everything you want out of a new sound system to help you pick the most suitable car electronics. Figure out if you need new speakers and amplifiers and what types would be best for the job. This way you can see if you can save any money.

This list will also help you stay within your budget. Some car electronics products may give you the best sound, but if you can't afford them, try to find products that don't break the bank. Do you want a new car audio system that makes you feel like you're at a concert? Do you just want one that has really great sound? This is an important factor to incorporate into your project.

Choose Your Car Electronics

Choose which type of speaker, receiver, amplifiers, subwoofers, and other car audio accessories is important to your car sound system installation. Make sure that they are all compatible with one another. One might have too much power and can hurt one of the others. You can also choose some components based on the features they have; this includes Bluetooth connection, satellite radio, and the option to use an AUX cord

Get Installation Tools

Figure out what wiring and adapters you need for the new products. This is essential before starting the project. You may also need a new dash kit if you change the layout of your car's dash. Secure these items to help the installation of car sound systems go faster. This way you don't have to continue to go to the store or wait for shipments to come in with your products.

Get Help From Professionals

Knowing how to install a new car audio system is crucial for this. You shouldn’t install one yourself if you don’t know everything that goes into it. You could damage the car electronics you have bought as well as your car’s current electronic system. It is important to leave this to the professionals if you don’t have the skills or knowledge to do so.
