JBL GX Series GX528 5.25" Coaxial Car Speakers (Open Box)

Every speaker or headphones I get are JBLs. I got a Flip 4 as a gift from work one time and was blown away. So after getting their Quantum810, Quantum TWS, Flip 4, and Earphones for the Cardo motorcycle bluetooth adapter, I figured why not get them for my van? Needless to say, it's a fantastic cheap upgrade. My old stock speakers had this horrible vibrating sound like the speakers were being ran through a fan. I basically haven't used the radio in the 2+ years I've had it. I just put the Flip 4 on the dash and connected my phone to that. I'm finally free! I put up a video of the comparison but my phone mic won't accurately sound how it compares in real life lol. Even with the volume maxed and Loudness turned on on the EQ, these things haven't vibrated or gave out. I normally don't listen to music that loud so I won't be stressing them out anyway. No-brainer upgrade. Hope to get their slim subwoofer soon!
