I have all Hertz Audio in my truck and it is great, I do not think that it is a cost effective solution but you will very much enjoy the gear. I am running the HSK 165 in the front and the HCX165 in the rear doors off of an HP4 rated at at total of 920W RMS....sweet \:\) and the HX300D with a HP2 rated at 1200W RMS at 4ohms. There isn't a Duramax 2500 around that sounds like this truck LOL.
