Jeep audio upgrades Coulsdon London Surrey

Really enjoyed this one. We pulled out the manufacturers audio system that just doesn’t cut it and upgraded it with Morel front and rear speakers. We then added a 5 Channel HD Jl audio amplifier to give it a nice bit of power and used a 12” Cerwin Vega sub to give it a nice kick. The end result was one happy customer.
