Great wire! very flyable which was exactly what we were looking for.

This was a perfect fit for what we needed. Very flexible and east to work with. We needed to replace the speaker wire on a portable sound system and this was perfect!

Great speaker

Love it. Sounds so much better than the stock subwoofer speaker. The only problem I had I thought it would be plug and play. It took me a lot of searching to figure out how to hook it up to my system.

Front and Rear Speakers

I have these speakers installed in my Ford Ranger, and they sound phenomenal when paired with the IDs18 head unit. My only wish is that there was a 6x8 model in this series to better fill the speaker area.
