i'm going to tackle this next week the questions i have are this.

1)anyone mount their nav/gps reciever under their dash with good results?

2)how many watts rms would give me great/excellent sound,i have a kicker zr 850.4 but it really dosent fit the truck well.

3)i have component speakers in the front doors and was going to hook them to the front amp/then was going to run the back 4 speakers off the rear amp in parallel so they would be at two ohms.(the amp is two ohm stable)will this cause a fader issue with the volume ?


any tips a to getting a great sounding system in a truck this big using the stock speaker locations and no subs?
thanks
