If you want simple cheap sound in your car and have music on your mobile phone and blue tooth you could do what I did and get a $50 blue tooth amp and wire it to your front speakers. I purchased a pair of $35 speakers (Here is the Link to what I bought) and replaced my originals in the dash, I had to remove the rubber around the magnet and make a 3/8 spacer (the tweeter is tall) and drill holes to match the old ones. ( ) and I put it in my center compartment, wired directly to my battery and ran the radio power wire to the switched wire on the new amp. I use my IPhone to control the volume and plan to put a small speaker box way in the back. Works great and I don't have any static! My siriusXM radio app works great and best of all no bubba effect to the car.

Before I replaced my whole radio with a Retrosound last year I used one of those AUX input devices that inserts into the antenna cable. I think I recall it was $85 but that was several years ago when the technology was new?

Great idea - been thinking about something like that a while.

I actually kind of like the old radio and kick panel speakers for nostalgia so I'd stick to some sort of low box behind me under the folded down convertible top.
