Clemsonfan15 the only problem i am noticing now the day after the install is a slightly louder engine noise from within the cabin. I think what happened is they did not want to put a hole through the rubber firewall because i have other standard car wiring going through it, Instead the lifted the bottom up slightly and put the wiring underneath. I need to fix that. I think ill slice the firewall a tad bit so the wire can get into the middle and this way the firewall will pop back in place. As far as my tint goes i have 5 percent on the front windows and since the rest of the windows came with tint from the dealership (tinted glass) they put 20 percent on the bacj to even out the front and back windows.
