JBL Power Amplifiers Editorial Review
This compact 4-channel amp is a great purchase for anyone looking for better sound quality in their car. The High Pass filter allows for adjustment of the crossover frequency and it works well for powering door and rear interior speakers. The size and power of the amp make it easy to install and the adjustable high and low pass plus bass boost really lets you dial in the system for optimal sound quality. Reviewers have noted that it is great for powering both rear and door speakers, with many noting that it is much better than stock amps and half the size. However, a few reviewers had issues with the amp constantly cutting in and out or not making much of a difference in sound quality from their factory unit. Additionally, some complained of the lack of caps to protect the naked terminals. Overall though, this is a great amp for anyone looking to upgrade their car's sound system on a budget.
