Great full range amp. Replaced an old worn out class AB with this. Have 1 gain completly down and the other about 1/4 and its crushing my door/front stage speakers. The value here cannot be beat!

Just finished installing in my 2011 Xterra, and this thing is smashing my new JBL club series in the front and back doors. It’s pretty wild how much power is coming out and the gain is almost at nothing. I was considered adding an 8” sub at some point but probably won’t with this amp driving those 4 6x9s. My first self install, so that was an experience, but for $85 this is well worth its value! Installed with Recoil’s 8 gauge 4-channel amp install kit and it had everything I needed. Very impressed overall, would recommend both amp and install kit (PCK84).

This DI550.4 is an absolute champion for it compact size and great performance. Clean, plenty of power, great sounding, and runs cool as a cucumber. I’m powering the Recoil REM ECHO 6.5 components with the same series Recoil coaxials. I’m crossing them at HPF 120hz and they sound clean, articulate, with some good slap in the mid range frequencies. I’m not running them as a mid bass speakers but more towards excellent mid range tonal quality with great accuracy. I using about 45 to 50 watts ( 55% GAIN ) per channel on the DI550.4 and these get insanely loud at only 2/3rds of the head unit volume. I have a Stinger 12 inch sub combo with enclosure 700 watts RMS/ 1200 watts max running on a Stinger MT1000.1 mono amp doing all the heavy lifting in the lower frequencies…Great product RECOIL. I will be buying more products from you real soon!!!
