Sound stage comes into focus

This was literally a five minute upgrade. Did a sound check before and after by playing some classical music that has a full range of sounds, I was seriously impressed in the improvements! Actually having tweeters makes a HUGE difference. On the low end, clearly a 3.5" woofer isn't going to give you deep bass, but it was so much more clear! The before and after was like focusing a camera lens and seeing the image snap into focus, just wonderful!

MB Quart JC-108 blew in two hours of usage

Blew up in 2 hours of usage. Complete crap product do not buy it! It did sound great for about 2 hours, then crap from there. I have a stock 8.4 in screen radio in my 2021 Jeep Gladiator, just for your reference.

Pros: None

Cons: Sound terrible after what I would call normal usage.

Crutchfield response on 9/1/2021
After receiving David's feedback, we looked up his order and found that his speakers are still under warranty. While his order is beyond Crutchfield's 60-day return policy, he can contact MB Quart at 866-636-6299 for further information about the 1-year warranty on these speakers.
