JBL Mono, 300w x 1 Amplifier. Compact size. High and low level input. Variable crossover and bass boost. Mono Block Compact. You can use 2 subwoofers with this, awesome output. Selling reason: I don’t have a car for the past year, and I haven’t even used it for 6 months, bought it from UK. Price is slightly negotiable, don’t offer such a price that I can't give it for. People who know JBL and pure class only they know how its output is going to be. 73.
