SRI Signal Summing Module

Please contact your local distributor for current pricing and availability. 


Today's vehicles are more challenging than ever to integrate aftermarket audio components into these days. Many vehicles don't leave the ability to swap out the factory radio with something more appealing and lets say it, a better sounding solution into its place. This traditionally leaves you with having to integrate your system to the factory speaker leads which in many cases are not full range and are frequency limited to the application of the speakers that were hooked up to them. Don't throw in the towel yet.

The SRI is an easy to use, compact and extremely effective signal summing module that allows you to combine these dedicated limited frequency source leads and combine those signals into a full range usable signal allowing you to build that dream audio system in your vehicle the way that you want it. After the initial connection setup is as simple as placing the provided CD into your music source and turn some dials till they turn green. After that, it's sky's the limit.
