Are the speakers waterproof? My bike stays outside so I need a waterproof setup.

The speakers are very durable (Polypropylene cones, rubber surrounds) but are not classified as "WaterProof".

ryan Jan 21, 2019 (Staff)

They are all weather. I have washed my motorcycle multiple times with no ill effects.

brad Jan 21, 2019

Will These Four Speakers Fit Into My Front Fairing As The Factory Ones Do? Or Are These Set Up For Two Up Front & Two In The Rear Bags? My Bike Does Not Have Factory Speakers In The Rear Bags. My 07 HD Has Two Lower & Two Upper Speakers In My Fairing . Thank You

The speakers are the same size. My 06 street glide has only 2 speakers in the fairing and 2 of these fit plug and play. And they sound great with the amp.

jeff Mar 21, 2018

Depends weather or not your fairing is stock or aftermarket.All 4 will not fit in a stock fairing.unless you have four already.I don't know what kind of bike we are referring too.

james Mar 21, 2018

Yes they will fit into your front fairing. I have a 13 RG and they fit no problem. You mount them internally. Also the second set I put in the rear on the trunk cause that's what my bike has but you can mount them wherever you want. Hope this helps.

jeremy Mar 21, 2018

I am wondering if the amp is waterproof?

I don't think so , But it mounted under my faring on my 06 Ultra Glide on top of radio . Very little water will get on it there .

tim Jul 04, 2017

If I remember correctly it's more water resistant than normal amplifiers but no amplifiers are waterproof mainly because they need a way for heat to escape. Humid air won't hurt it but I would still keep it as protected as you can

jason Jul 03, 2017

No.

jeff Jul 02, 2017

I don't believe so. It is supposed to be mounted within the fairing.
