Installed this amp to power a single JBL GT5 12". So far the amp has provided a flawless performance. You should spend some time fine tuning the low pass filter settings to minimize distortion. The bass boost switch isn't needed for a single sub, and the remote control does not need to be turned all the way up for satisfactory results.
I would recommend you use an 8 ga. power cord and ground for your installation. Ground the amp with 24" or less of 8 ga. ground cord. The "Boss" emblem lights up when the power is on, so you might want to install the amp where it will not reflect onto your rear windshield.
I have not felt any excess heat coming from this amp yet. The compact size is great for concealing in small spaces. I was able to install it in the back of an F-150 cab and still have enough room for cooling. This is my first experience with a Boss amplifier, and I definitely pleased with the results.
