yea, i should clarify my setup right now...
in all the stock locations i have 2 ways that are 60 watts RMS at 4 ohms
2 subs that are 150 watts RMS at 4 ohms wired in parallel so they are effectively 2 ohms
amp puts out
50x4 at 4 ohms to stock locations
300x1 at 2 ohms to the subs
all wires have been upgraded to 14 ga monster cable
wires to the subs are 12ga monster cable
twisted pair rockford fosgate signal wires from the head unit run completely separately of any other wires except for the ECM directly below the head unit
head unit uses stock power input with a noise filter on it and is grounded directly to the firewall
4 ga stinger power wire to amp
4 ga stinger ground wire (about 12" grounded under drivers seat bracket, sanded the paint off)
150 SF dynamat on floor and doors
