Our hands on Engineering Research and Development team builds quality into our JENSEN & Voyager products from the beginning by expertly designing each product from the ground up and validating all designs through extensive testing that is primarily conducted in our own on-site test lab. Therefore, JENSEN Audio & Video products and Voyager Camera Systems offer MORE durability and performance than you would expect from standard electronics.

Temperature/Vibration Chamber

Long-Duration product exposure to constant random-frequency operational vibration and non-operational vibration to simulate rugged road conditions. Simultaneous temperature cycle and vibration exposure are also conducted for additional data that is relevant to detecting potential material/component weaknesses and calculating product life-expectancy.

UV/Salt Fog Corrosive Exposure Chamber

Exterior components are subjected to accelerated UV exposure that equates to 5-7 years of actual outdoor exposure to assure you that your electronics will look great for many years.  In addition, product and product components are subjected to dry/wet cycles of highly corrosive fog/mist to test for corrosion resistance and corrosion protection effectiveness.

High/Low Operating Temperature

Long-Duration product exposure to operational temperature extremes and rapid temperature cycles that are experienced in outdoor mobile applications. In addition we test for High humidity introduced at high-temp to test effectiveness of circuit corrosion protection (conformal coating).

High/Low Storage Temperature

Ensures your JENSEN products will perform even after prolonged periods of storage with no power in extreme hot or cold temperatures.

Temperature Cycle

Used to ensure powered components withstand temperature fluctuations.

Customer Reviews

  1. Replaced sound bar speakers on 93 wrangler
    Review by Chester on 4/1/2013
    These speakers sound great and are an awesome deal at $18. They fit perfectly and were easy to install.
  2. great replacement for my 94 Jeep Wrangler
    Review by Alan on 6/21/2012
    Replaced the stock 18 year old Jensen speakers in the sound bar. These fit great and work well.
    Had to cut factory wiring and splice on .250" female faston connectors (no big deal), and I had to find my own screws, since they did not come with any.
    Wished they would have a little more base, but I can't complain for a 4" 120 watt waterproof speaker for $17
