Sony RDH-GTK37iP G-Tank

This model, nicknamed G-Tank, is too heavy to carry on the streets (30.9 lbs, 14 kg). It doesn't accept batteries anyway. It's basically intended to be a house party blaster. It's got LED's that change color on a light bar in front of the woofers. The speakers are painted silver to reflect this light. For audio sources, it's got an AM/FM tuner, Bluetooth, Aux jacks, USB, and iPhone dock. It measures 30.4 inches long, 12.75 inches high, and 15.25 inches deep. It's got 4 speakers (8 inch woofers and 2.5 inch tweeters). On the box it claims to produce 420 watts, but the owners manual says 100 watts per channel into 3.5 ohms at 1kHz and 1% THD. I don't see how either claim could be true, since the label on the back says it consumes only 85 watts.

NOTE: There is a smaller, cheaper model called the RDH-GTK17iP which is 26.75 inches long, weighs 26.5 lbs, and has smaller speakers (6.5 inch woofers, 1.5 inch tweeters).
