Speaking of competitors, there is something that JL has with its budget range of apps that the others don’t, and that in an unwavering dedication to performance.

The JX1000/1D is an unassuming mono amp. There is nothing to the shell of the device outside of the model name and number. Don’t let that deceive you.

Inside, the components inside are carefully tailored so they’re as power saving to your car’s battery as possible. Currently being a hair under $300 it makes it in the mid-range for most folks looking for their first amp.
