Me likey a lot!!!!

As previously stated , I am very pleased with this amplifier. Previous to my current setup I was running a slash series 300/4 along with 600/1 and was happy or so I thought. Car was stolen then retrieved minus my system. Presently have the Jl hd600/4 along with 750/1. With that comes a very nice ceiling. Save money by doing it right the first time. 👍👍Read full review...

JL Audio HD600/4

Clean, powerful and easily fits under a car seat. AT $300 cheaper than new, well worth the price.
