JL Audio JX500/1 Car Amplifier
Underneath the plain exterior design of the JL Audio JX500/1 lies quality components which make up the Class AB amplifier. This mono amplifier puts out an impressive 500 watts RMS with a 2-ohm impedance, with a still-high 340 watts RMS at 4 ohms. This is enough power to drive even midrange subwoofers with higher power handling ratings, which leaves little doubt that the JX500/1 is an excellent value for the price. However, the disadvantage of the 'budget' construction make themselves known. The JX500/1 lacks cooling fins or an internal fan - as paired with a hot-running Class AB amplifier, it becomes essential to ensure that adequate cooling measures are taken to prevent overheating or damage to the components.
