The owner of this Suburban came in looking to crank up the volume of there bass in their Suburban, so we installed two subwoofers. Not just any subwoofers, two top of the line 12 inch 12W6V3-D4 JL Audio subwoofers. To power these beasts we used 2 Kenwood Excelon XR600-1’s 600 watts RMS to each W6. This vehicle had so much bass we had to add a GTO-504ez 4 channel amplifier to the door speakers so you could hear more than just bass. Last but not least we added a 5906v the top of line Viper alarm with remote start. This car was breathtaking after we got done with it.
