Not perfect but still nice

Power: Not really as powerful as it's rated but there is still plenty of power there. I would say it's more like 100-125wX4 on the full range and 300-350x1 on the sub channel. Be advised though, there is a HUGE difference between running 2ohm and 4 ohm on the sub channel. Be careful if you are running small subs like 6.5's or lower end 8's.

Sound Quality: Pretty nice. I am running a JVC KW-R900BT headunit and the sound is fairly open and well separated. The sub channel remote is a little more like an on-off switch than a variable volume control.

Features: Separate Crossovers for every channel is nice for an amp in this price range. The sub phase switch is nice too...makes the amp fairly adaptable for multiple setups if you are the kind of guy who changes things around alot.

Things that could be improved upon: It might just be my amp but my cros overs are misprinted...the inputs are correct but the front and rear x-overs are switched. Took me a sec to figure this out when I was tuning the system. Also, along with the remotes sensitivity issues the shape of the thing is not my cup of tea but that's a personal opinion.

It seems to get a little warm, though it's nothing too bad. But my install is on my vanity cover in my 06 GTO so it has airflow to it and I could foresee overheating issues in a tight install (like under a seat or behind a interior panel).

Overall I give 4 out of 5. Sounds really good, is pretty powerful and is really flexible. Just hope there is a cure for the remote and that the x-over markings are not a common mistake.

really hot and shuts down. after a few days, there were noise from the speakers of the engine, thus if you put another amplifier, the noise is not present. not satisfied with the purchase.
