If the problem was confined to the radio in vehicle,I would be sure to wire the radio in to the fuse/relay block .Not on a random wire ,or move the radio wiring to a different fuse block terminal,but with it causing problems inside your house it must be airborne static.Remember also theres a lot of wireless transmitters on your truck.Low tire pressure sensors are wireless transmitters so is On Star if equiped,keyless entry etc.

A lot of things can radiate "popping static" while ignition noise is unique being RPM dependent. That should give you a clue where to start and we can take it from there once the source has been isolated. More information please, feed me.

I would suggest running the ground lead to a point on the firewall . You'r am/fm radio ground is bolted to a spot on the firewall . I'd make sure that when and if you do bolt directly to the firewall make sure the surface area is free of paint , oil's and the area is clean shiny steel and use a star washer so that when you bolt that ground lead down it'll have a much better contact . I'd also suggest using the direct to battery method and use 10ga wire with a 25amp fuse at the battery .

That's what most of you'r HIGH end stereo shop's do for amp installs and so do the 2-way radio shop's .

Is it on just on one frequency, or is it on more than one?

Some vehilces has RF issues, Saturns put a spur out on 146.52 Mhz and I can hear it when they are about 30 feet away.
