My Freightliner over the road tractor has a really crappy sound system. Especially with the XM satellite radio, which is pretty decent quality sound. So I'm thinking outside the box here....

I don't want to spend a ton of money on upgrading the crappy head unit and speakers, built into the truck. Already have the XM unit which uses a cassette adapter. What I am thinking of doing, and have the space for it, is getting a 12 volt to 120 V power inverter, getting a decent set of 2.1 powered speakers, like Klipsch and mounting the small satellites up in the cab, and the bass module behind me in the bunk. I can use the line out from the XM receiver directly into the speaker input. Since it's just music, no need for surround setup like 4.1.

Think it will work out?

mike it should work !
the truck radio bad sound system my be a simple bad ground - if it was in a car i say a bad set of spark plug wires . but its a semi and i know they dont have spark plug wires from what i understand ! in the old days a spark arrester could fix this problem . but were talking a semi and this is a animal i have no exsperince on ! i know part of the system in a semi is 24 v . but that about all know abut them !

Not a line noise problem with the truck stereo, just crappy, worn out speakers and hiss from the cassette adapter for the XM receiver to stereo hookup....

That should work just fine as long as you're using powered speakers.

Yeah Ego, reason I need the power invertor for 110 volt, for the speakers. Going to just cut the truck system out of the loop Could use headphones actually, but they frown on that while driving in most places And a set of Klipsch speakers would kick arse in the confines of the cab.....
