good amp great price
this amp looks good ,plays good, runs 2ohm in front, 4ohms for rear.i play it loud everyday.feels hot but never goes above the temperature stated in the install manual. tested with heat gun. it comes with 4 spacers to get airflow clearance when the fan is on,i replace the spacers with taller spacers amp runs much cooler

Great privacy for the Value!
The FLI Audio 4 channel amps is more then enough to power your mid and high range speakers. The clarity is prestige and the amount of power this thing puts out for the money is well worth it. I never owned a FLI audio amplifier before this one, but would definitely by from this manufacturer again.
Cons: Amplifier needs to have more settings as far as a high pass filter for the rear speakers on the amp. Just has a low pass and full range.

good amp
This is a good amp, sounds good, looks good, perfect for it's price. I might even buy another if it makes my subs sound good too, right now it's hooked up to my 4 kicker ds series speakers.

Nice amp
Clean sound, nice bass mid and highs. I'm running 4 Boss Audio P69.4C 6X9" speakers in a sealed box, 2 in each box, 2 Bazooka BT1214 12" bass tube. The Boss Audio 6X9" speakers are on the 1&2 channel with the HP set at 50hz, and load at 2ohm. The Bazooka 12" bass tubes are on the 3&4 channel with the LP set at 60hz and bass boost at 6db and load at 4ohm. Amp has a cooling fan, and it runs cool. Sounds real nice in my SUV.

Great Value! Hasn't Overheated!
A great looking Amp, I have it running 2 factory door speakers and 2 12's.
Which works great for that set up, being that the 1&2 channels have the high pass. The 3&4 channels (my subs) have the low pass. The hi low speaker thing didn't work when installed but now works fine. Oh and the fan is small and on the bottom of the amp.
