HI people, I'm new to owning this one,So I went and buy anew one for it at $290 and plug it in 15 min later it burns out! so I don't know what to do, so I sent it to the shop and they told me the system was fine! BUT I'm wary of buying an another one! so my problem is if there is other models that will fit it? Because it's very pricey buying an another one,so if I can buy an used one!03 magnum 330 2x4 sorry
