They were relieved to see we stood up to what others have already known.
First project was a 98 Ford F250 Diesel truck.
Had an existing Pioneer Premier headunit installed but everything else just wasn't up to snuff....and the pioneer was showing it's age.
So I replaced it with a 7" Fold-out DVD player with BT, USB and Backup Camera for when he hooks up to his RV.
Then I replaced the front OEM speakers with Memphis Audio 5x7 Speakers and Rear JVC 6x9s in Custom Bedliner Boxes....with enough wire so they can be relocated outside of the truck if the couple wasn't to jam out to some tunes outside of the truck.
Next up after that was the RV aforementioned above.
It had a very dated AM/FM/Cassette receiver powering some old 6.5" ceiling mount speakers.
I replaced all the speakers with Pioneer Marine speakers and fabricated a new face plate to house the new Pioneer BT/Aux/USB headunit. Now they have plenty of inputs and power to have a party anytime/anywhere.
