Review: Also replace Audi Mid range driver - Read about these on the Audi forum and the other reviewer, Mal, installed these. They are well made speakers and look good. The sound is a whole lot better than stock, very clear higher mid range, and for the price, definitely worth it. I used these to replace the 3 inch mid range B&O (Actually audi speakers) in my A4. The A4 and A5 share the same sound system in the front for the B&O and are direct 4-ohm replacements. Brackets need to be made for a nice fit.
Review: Its a significant upgrade to your old speakers for older cars - So i own a 1991 Mitsubishi 3000 gt. Ived decided to upgrade the speakers since they are very old by todays standards. I was looking for speakers that would not only fit but work for my car. I came across these speakers by a video and decided to give them a try. They are easy to install with a plug and play wires( i think it depends on your car) They come in one so if you thinking of getting multiple then you need to buy multiple. i needed 2 so i bought 2. They are good starter speakers for those who need an upgrade but short on cash.

### ⭐⭐⭐⭐ Using as a dash speaker
*by J***S on December 5, 2025*

A little bulky for a dash speaker but I was able to make it work. They sound great on axis - but using the windshield as a reflective surface loses you some treble but still very enjoyable
