4-26-2018 update. So far the amp as been rock solid. No problems at all.
I matched it with the new JVC KD-X35MBS head unit that provides all the FM/Bluetooth/Sirius sources I wanted and has all the equalizer controls, cross-over settings and balance/fade controls that I needed. (Note that this amp does not have any controls of its own, its just an amp. You will need to pair it with a head unit that gives you all the audio controls you need). I also used two pairs of Clarion 6.5" marine speakers mounted in the open part of the hull and in the enclosed cabin (i.e. set up as front and rear speakers).
I am getting good punchy sound across the full range of frequencies with more than acceptable levels of bass (after a little tweaking of the equalizer controls on the head unit.). Volume is more than sufficient to cut through clearly with the engine and other ambient noise of a busy recreational lake.
It is important to match this amp with speakers of the correct power handling. This amp will push out 100W max and 45W RMS. Its the RMS number you need to care about as this is the number that reflects the true continuous power capability without distorting. I matched with speakers rated at 100W max and 50W RMS which is ideal. If you match it with speakers of a lower RMS they will distort at higher volume levels. Conversely, if you match with speakers rated at a much higher RMS (say, more than 70) this little amp will likely not drive the voice coil in the speaker hard enough to develop the full sound the speaker is capable of.
This amp is intended to be an affordable, good quality upgrade over stock radios and in that capacity it does a fantastic job. If you are looking for a high-end audio upgrade that is going "kick butt" this isn't the amp for you as it won't have the power or the features needed to support a high-end rig.
I rated it only 4 stars because I am concerned about it failing due to heat. This little amp gets hot fast and the aluminum heat sink seems a little thin to fully dissipate the heat build up. Instructions say to install in a heat free location with good airflow and not in direct sunlight. Well, there is no such place on a fiberglass boat in the middle of summer! I installed mine in a bulkhead inside the enclosed cabin. The bulkhead has an opening to the outside under the dash for some airflow. That is about the coolest place on the boat that isn't directly exposed to water (this amp is not sealed - I would not recommend getting it wet!) but even so the cabin easily reaches 100 degrees or more, so we'll see what happens... If it makes it through the summer I'll upgrade to five stars.
The amp comes with a few extra lengths of cable fitted with red and white connectors, as well as some mounting screws, and a few zip ties which you may use to secure it in place.
For a name brand amp under a hundred bucks, it's pretty hard to beat. I am very happy with the purchase and would most definitely buy it again.
