Small Size

JBL DSP4086

RMS Power: 40 Watts
Peak Power: N/A
Best Frequency Response: 10-22k Hz
Amplifier Class: D

Adding an amplifier to increase power and a digital signal converter to enhance sound quality is one of the finest ways to get better sound clarity in your automobile. JBL’s very small DSP4086 8-channel amplifier can do both by delivering eight channels at 40 watts RMS and shaping the sound on your Windows PC with potent tuning software.

The small size of the amp makes it perfect for installation in most cars. The front speakers, back speakers, front center channel, and back subwoofer of your car can all send signals to the DSP4086. Once those signals have been processed, eight powered outputs can be made, and your front tweeters can be powered and controlled.

Each channel has a 31-band EQ that can be switched between parametric and graphic, as well as fully adjustable high-, low-, and band-pass filtration with customizable slopes, and time delay that can be adjusted from 0 to 180 degrees, and a time delay of up to 12 milliseconds.

Every input can be assigned to an output, and signals can be added to provide a full-range signal that can be processed. All of these things make the DSP4086 a great small-size 8-channel car amplifier to have in your vehicle.
