Can I mount the distribution block in the engine compartment? I wanted to keep the dash amp running front to keep the cable run and speaker wires short. I will also be driving the car to NYC at times and may want to pull the 4channel under the seat, granted I may have know rear or subs but no theft. If the install is clean enough I will then run the 4 doors from the 4 channel like you suggest and then the sub from the dash amp.
