Replacing TT radio with used car radio ???

In a class A often there is an amplifier, but if you swap out the radio the amplifier will remain since the dash radio is a standard car radio.

in a trailer, Often all the radios are standard car radios to start with, Nothing special about them, some are DIN, some Double DIN some 1.5 DIN (DIN is the French national brueau of standards and the 1, 1.5, 2 refer to the size of the cut out which as you said you can re-do) so with very few exceptions they all replace each other.. and with the DIN cutout radios it's very easy to swap 'em out.

You may with to get an Adapter cable (www.crutchfield.com should have 'em) if the radio is a different make from the one you have.. Saves cutting and splicing wires.. Personally.. I'd cut and splice, but then I have the tools and training.

I replaced my OEM radio with a Panasonic, I think, and the only problem I have is that the wiring from the radio for the various options like Fade, Left/Right speakers, etc. were never connected properly so we just use the radio with the speakers that are connected.

Depending on how old the tech of the failed radio is, you may find you have to do a little extra wiring to keep the Time and Station Memory "warm" when you turn the TT's house battery off for storage.

Any way I look at it, I see this swap as "easy."

X2 on walmart.

They have a 'huge' selection of radios and really cheap even for some pretty nice pricey brand names.

Sound system store wanted $800 bucks to replace the radio in my MH. I picked up a $120.00 radio for $79 bucks on sale that sounds way better than the factory one did and has 4 times the options on it. Not to mention some totally unecessary but cool blue lights.:B Instructions included were easy enough for me to install too!

Buy a $100 new radio from Crutchfield. It will probably have a USB slot for mp3's. I use a $10 NanoUsb for music. If stolen I'm out $10. Plus the new radio will work. Crutchfield will usually throw in the wiring harness and dash plate.

Go to walmart and buy a $50 car radio. Or splurge and get a nicer one. Even check out Crutchfield (do a search, they have a ton of stuff).
Almost all have 40-50w of power power channel and will not require an external amplifier.

1) No, most auto head units have their own amplifier.
2)Maybe, but not typical.

Look around at Crutchfield to see what's available and for installation instructions. You can use different bezels to accommodate different sizes of radios.
