Helix HX-4634
The Helix HX-4634 has 8-inch woofers, 2 tape decks, and 2 antennas. It also has RCA inputs so you can connect your MP3 player. It measures 24.75" wide, 14.25" tall, and 7" deep, takes nine D-cell batteries, and was made in Taiwan.
I have seen this model in both black and gold versions. There were also several re-branded versions of it, including the Mura MCS-1919, the Seltec GX-555, and the Trident DX-6000.
