Not that expensive , they sold for $49.95 new in 2001.
The new Bolt series amplifiers from the sick minds at Lightning Audio are designed to offer killer performance at an incredibly low price. The nuclear yellow finish scream for attention and you can even add an optional Cooling Turbine (CT-1) for enhanced cooling. The B2.150.2 is jam-packed with features including high-level inputs, fully variable built-in crossover, and juice-boost bass enhancement circuitry. The car audio industry was so impressed by the new Bolt amps; they awarded it an International CES 2001 Design & Engineering Innovations Award. Dollar-for-dollar, there’s not much out there that will deliver more thrills and chills than Bolt!
