The JD400/4’s controls can be found on the input panel of the amplifier, with all speaker and power connections located along the opposite end of the extruded aluminum chassis. Signal processing features include high or low-pass 12 dB / octave filters (defeatable) for each channel pair, with continuously variable frequency selection from 50-500 Hz, and dual-range, differential-balanced inputs capable of accepting line-level or speaker-level signals. Automatic turn-on capability (via signal sensing or DC-offset sensing) is standard equipment.
Onboard LED-clipping indicators are also included surrounding each input sensitivity control. This convenient feature lets you set your amplifier’s input sensitivity, quickly and accurately, without special equipment. You will also find a set of buffered, pass-through preamp outputs on-board, so you can pass signals to another amplifier.

Installed on 2 cars 1994 Miata and 2005 Scion XB
I installed both amp in both cars and the installation was very easy do to great electrical connectors both cars sound is very good using Pioneer double din touch screen head unit. Sound is very clean and has plenty of power both Amos was installed in the back 94 Miata in the trunk and on the 05 Scion XB also in t h e back. I love the quality of the J&L amps would buy again.

found this helpful.Amazing sound!
This amp is phenominal. I am blown away with how well it performs. I believe in name brands when it comes to sound, and J/L hit the nail on the head with this one. I am running two subs bridged in two channel mode and it has a punch. QUALITY like this is meant to be heared. I wonder how great it would sound on my 6x9's. Makes me wish i still had my jl1000/1 to pair it with. Thanks sonicelectronics! You made my day.

found this helpful.You cannot go wrong with this one.
I had been driving around in my Tundra for 3 years with the stock system. Friend picked my up one day with a proper system installed and I started researching parts the next day. Ended up completely stripping the interior out and upgraded from front to back.
Kenwood DDX9907XR HU, Focal Focal ES 165K components up front, JL coaxes in the rear, JL Audio CS112LG-TW3 Sub powered by a JD500/1 and this amazing little JD400/4 pushing the components and rear fill.
To say I am impressed by this amp is an understatement. JL made setting the gain idiotproof and this will play as loud and clear as my 51 Y/O ears can handle.
Cannot recommend enough.
