Can I use any personal stereo with the Rumble Road speaker system?
With the amplified version of Rumble Roads — the Premium model — you can use virtually any personal radio, or CD, cassette or MP3 player equipped with a standard 3.5mm mini-plug headphone jack. As noted above, for the relatively few devices manufactured with the newer 2.5mm stereo jacks, adapters are available from electronics stores. Products with “floating ground” amplifiers, such as very low-end FM radios, may not work optimally with Rumble Road™ speakers.
