Audi 80 Speaker FAQ

Should I upgrade the rear deck speakers or dashboard speakers first in my Audi 80?

Start with the 6.5 inch rear deck speakers. They handle more power and produce fuller bass response compared to the 4 inch dashboard units. The rear deck location typically allows 50-80 watts RMS handling, while dashboard speakers might only manage 25-40 watts. You'll notice immediate improvement in overall sound quality. The dashboard speakers can wait since they mainly fill in mid-range frequencies that the rear speakers already cover reasonably well.

Can I install component speakers in the rear deck of an Audi 80?

Yes, the rear deck accepts both coaxial and component configurations. Component speakers offer better imaging since you can position tweeters separately. However, mounting locations for tweeters might be limited unless you modify the interior panels. Most people stick with high-quality coaxials rated around 4 ohms impedance. The deck space accommodates deeper magnets, so you could run components rated up to 100 watts RMS if your amplifier supports it.

What's the frequency response difference between 4 inch and 6.5 inch speakers in the Audi 80?

The 4 inch dashboard speakers typically reproduce 80Hz to 20kHz, while 6.5 inch rear speakers can reach down to 45Hz. That low-end extension makes a significant difference. Dashboard units focus on midrange clarity around 1-5kHz where vocals sit. The larger rear speakers provide the foundation your Audi 80 system needs. You might want to consider a small subwoofer later since even 6.5 inch speakers struggle below 40Hz in most car environments.

Do I need an amplifier when upgrading speakers in my Audi 80?

The factory head unit probably outputs 15-20 watts per channel. Your new 6.5 inch speakers could handle 60+ watts easily, so an amplifier makes sense. Start with a 4-channel amp rated around 50 watts RMS at 4 ohms. This powers both dashboard and rear deck speakers properly. Without amplification, you're not getting full potential from upgraded speakers. The improvement in dynamics and clarity becomes obvious once you add clean power to quality speakers in the Audi 80.

Should I replace the dashboard speakers with larger ones in my Audi 80?

Stick with 4 inch speakers in the dashboard location. The mounting depth and opening size limit your options anyway. Focus on finding quality 4 inch full-range speakers with good midrange response around 200Hz to 8kHz. Efficiency matters more than size here - look for speakers rated 90dB or higher sensitivity. The dashboard position handles imaging and vocal clarity while your rear deck speakers provide the bass foundation your Audi 80 needs.
