Pods seems great
Color: Black
I have all Alpine in my jeep so I only bought these for the pods to mount on my roll bar. Pods seem great. Heavy duty construction should stand up well and I chose these because they can swivel and face any direction. No regret with this purchase

Not what I was expecting....but....
Color: Black
The seller was great in returning my item. The speakers didn't carry the low frequencies that I thought they would. However, I was running these with just my stereo and not pushing them with an amplifier. The price was good, the packaging was excellent and quality seemed very nice. Just not what I was hoping for with the bass response. I have to give four stars even though I didn't keep them. For most people, I think they'd work well.

Great housing, lousy speaker
Color: Black
I’m not usually one to write reviews but this need to be voiced. I installed both speakers today in my Jeep. Ran off of an amp correctly powered suited to the rms of these speakers. Ran them for a grand total of 45 minutes. And they died. The tweeter works fine but the woofer failed completely. For the 45 minutes that they worked they sounded great. The mounting was easy, housings are great but speakers are complete garbage.

Decent quality for low price
Color: Black
Easy to install, flexible mounting, seem well built. Not truly swivel as they can't be turned once installed (mount swivels to allow different angles between clamp/speaker direction when installing, but fixed once installed). Quality is what you expect for $100. Had to open up the enclosures and dump out plastic shards left in there from manufacturing (to avoid them buzzing when music playing). Overall satisfied, we'll see how long they last.

Great performance
Color: White
I couldn't be happier, a pair of these mounted on my wake tower with a decent amp are performing very nicely. Very loud clear acoustic sound quality, with good base and tweeter performance. Thank you for your services - much appreciated 👏
