This is an amazing amp. I have crystal clear lows, mids, and highs with this amp. My friends have other store bought brand name four-channel amps like kenwood and pioneer and rockford but personally i love the clarity of mine the best! Don't be fooled into thinking that SPL is a lower class brand, I also own the 2200 watt 2 channel Gorilla amp for my 2 12" subwoofers and i have the loudest setup at my school and I paid a small fraction of what they paid for their setups. I'm loving the SPL amp combo in my Jeep, and it gives me plenty to show off with for those times when i really want to turn up the volume, with no distortion whatsoever.
