Direct fit for B5 Audi
Perfect fit for my 99 Audi A4 with the Bose sound system. With the Bose speakers being 2 ohm it’s very hard to find replacement door speakers without replacing the entire sound system. These let me replace my blown out door speakers and retain the rest of the stock system. Sound quality is also very good.

Awesome!
Factory fit and hard to find 2 ohm speakers for my 1995 Corvette with Bose system. Upgraded to Cadillac 100W amps and Crutchfield bass blockers and they sound great!

Better than oem replacement. Fits Bose gold in oem corvette and Cadillac systems. Definitely worth the few dollars.

Perfect replacement for bose factory 4 inch speakers
Replaced the worn out Bose speakers in my 1993 Cadillac Eldorado. It sounds SO MUCH better! These speakers are designed to replace factory 2 ohm speakers in systems still using the factory amps. You shouldn't buy these if you're running an aftermarket system.

Perfect fit for B5 s4
Fits my front speakers in my B5 S4 PERFECT. No modifications needed, just reuse the bracket and the rubber piece from the old ones and plug them in.The sound quality is OK. Not the best, not the worst. Highs and lows are still lacking, much like the Bose speakers they replaced. I found that tuning the speakers using the hidden Bose equalizer menu was the best for sound quality (Just Google this for how to use it). The best number combination for me was 77898811.
