Hi, all. I have an 01 gt w/mach 460 system. I have hooked up my system like the one described in mustang world but I think the signal is too weak. The subs do not pound at all. I have a blaupunkt 2150 amp which puts out 400 watts rms @4ohms to the subs. The subs are 2 10-inch infinity perfects wired to 4-ohms. The amp comes with something like a line out converter as it doesn't have high level inputs. Also, the amp should turn on whenever it receives a signal but it doesn't so I had to run a remote wire. Is there a different wire that i can tap. Also tried tapping the above the rear deck and I only gave me highs. Where would the wires to the subs be from the amps? Does anyone have a wiring diagram for the rear amp/speaker configuration. Thanks in advance.
