The G-Series amplifiers are the real value amplifiers from JL Audio. With the emphasis on quality and not just on the price, The G-Series amplifiers give you the greatest performance for your money.

The G-Max amplifier uses technology that is often seen in the higher end amplifiers. It features differential-balanced inputs, exceptional signal processing sections, an unique “never quit” rollback protection circuit, and JL Audio's super-clean, patented amplifier circuits. With all this great technology, the G-Max is a high-end amplifier for a middle-end price.

This was one of few amps that met the space requirements of my very specific fitment requirements and still has the power to meet my needs. It's nothing glorious, but it fits the bill. I have no complaints.

Customer Testimonial

Bought a pair of speakers for my daughter's car for her birthday. Speakers were here two days after I ordered. That time + free shipping and a product exactly as described. Outstanding service! Have definitely added Sonic Electronix.com to my favorites list.
