Are Stinger wires good? The shop I am probably getting to install my system uses Stinger. Also they gave me a price est. of $1,400 to install my system, I have an Alpine Type X 12" sub, Alpine MRD 1005 monoblock amp, and a Tsunami 5 farad cap, the price includes a Pioneer indash screen, all wiring, custom built ported box, all installed. What do you think about that price?
