I got 4 6.5s and mounted them on a ds18 bar in my jeep tj. They look great and fit perfectly. The packaging was very very nice. I can’t wait to hear them.

    • Not bad
Not bad for the price but mids and base are lacking. If your going to add a subwoofer it should be good.

    • Outstanding
I bought these and the next size up. The six inch speakers have incredible clarity of sound. I am using them in a camper VW Bus with extra line to take them outside, even if it’s raining while camping

    • WORKED DIRECTLY WITH MY RIDE COMMAND
I was able to connect these directly to my ride command harness that was already present on my 2023 Polaris RZR Turbo R, sound great, but I will say that the mounting clamps were a bit of a pain.

    • Horrible sound.
The media could not be loaded. Horrible sound. I thought it was the radio they were connected to until we tried my old Klipsch outdoor speakers and It's all mids and highs. And when you adjust for more bass in the radio, the speaker sounds even worse. I tried to get a video showing my 15 year old speakers vs the pods. ... show more

    • Exactly what the doc ordered
The media could not be loaded. I have nothing negative to say about these. They rock with a deck just fine at 22 watts rms. I'm sure an amp would push them further. What I like most are the solid aluminum mounts that you can swivel before installing them so you can aim them in any direction but this must be done before mounting them they will not swivel after they are mounted and I would not want them to because then obviously they would not mount as solid as they do. Other speakers I've seen mounted on motorcycle seem likely to break and fall off. Speakers sound as good as any other car speakers I've bought in the past. ... show more
