    I was riding my ATV when it came a small rain shower. I still had my music going because my sound system was supposed to be water proof or resistance. WRONG!!! my system fried. I tried contacting the seller because of what happened, but no responce. I've waited almost a week, NOTHING! I will never buy from Online Sound again. I will also tell every one I meet not to do so also. Very good product, just BAD! Reperasentation!!!

    gets the job done.

    first off let me start by saying for 60 bucks it is a great product (you get what you pay for) it was better than i expect sound wise. its not going to blow your ears away but it is also not crap i am satisfied with the purchase. there is only one complaint/word of advice. the bluetooth does not work it powers up and connects to your phone but other than that no sound comes out. i ended up having to hardline my bluetooth adapter to it. i was told by others that it happens to them too! they ended up harlining it too. but like i said it sounds good.

    Junk

    The amp is of low quality and picks up electronic sounds on the vehicle. I purchased a more expensive name brand amp and problem solved. Audio guy said it’s of low quality with a Chanel problem.

    Atv Speakers

    I have a 18 scrambler 1000xp with dual big gun exhaust and when im on the gas I can still hear this little speakers over the exhuast note. Very easy install everything is of good quality besides the handle bar mounts. Cheap design on the bar mounts and they dont clamp down very tight. Other than that nice little setup and id reccomend to others!

    Great quality for price clean system

    It sounds great plenty loud enough. With loud pipes you can turn it up loud enough to not hear anything but music. The only down fall is if you have it all the way up it does distort some but that is all the way up and unless your deaf at 75 half way is almost to loud for safety of not hearing other cars. I do have a windshield so that may have some to do with it but for the price it’s hard to beat. Plus once you connect phone or whatever to Bluetooth, every time I get on nick and turn the key it immediately connects, no going into settings and finding! My old system was like that! Again worth the money (not retail for $200) but definitely $60-75.

    Awesome for price

    These are really good for the price. Only down fall the clamps are not big enough to go on my rzr 900 roll cage. We had to cut plug off at end in order to slide the clamps off and inserted EMT hangers on it and rewired plug. Truly are waterproof sprayed rzr off and the amp and speakers then connected phone it played just fine. Sound quality is loud and clear sound just as good as the expensive speakers u get. Good enough to hear over the rzr sound and everything.
