As a volunteer firefighter, I bought the SA315P to work together with my Epsilon EPSL1 series. The instalation is extremely easy. It fitted perfectly under the hood of my Renault Logan using the Universal SAK1 mounting kit. The sound is loud and clear. I am very happy with my purchase and I would recommend other volunteers to consider this option. Outstanding product by Whelen. Couldn't expect any less.
