A:AnswerTheir are different CompR models and different CompC models some CompR come in 2 ohm and 4 ohm and some CompC come with Dual voice coils and others don't. Also all they have different watts and frequencies and the list goes on and on. To basically sum it up if you are looking for a better cleaner bass the CompR is for you but if you want a cheaper woofer the CompC is still good quality.
A:AnswerYes, but be careful how you use them. It won't damage them right away. I have owned this product for a few years and they sound really good. Follow what the installer says and you will enjoy good quality bass.
