This amp is excellent. I bought this amp, the Alpine 12" and an LC1 audio control and stuck it all in my wifes 2022 4runner after purchasing a skar audio sub enclosure that is made to fit. The amp only has the RCA type inputs and no speaker wire input connections, which is why i picked up an LC1. That LC1 is highly recommended if you are using the type of set up with a factory sound system. Amp is 600 watts and really works well with the alpine 12" sub. Amp does not get hot at all under moderate load and is small enough that i could mount it under the driver seat. The amp came with everything needed and plenty of length on all the wiring. It doesnt have a sense wire for the auto shut-off but has the normal 12v remote wire. If you need the sense function, the LC1 audio control has that. I've had the whole set up installed for a month or less. I think 6 to 12 months will be a good time frame to test the quality of this set up but best buy is pretty much blowing up my email for feedback the day after i made the purchase. I'm guessing the quality is good but would need more time to assess that for sure.

Paired with an s2-s10d2 + alpine knob and it cranks. Mine was rated a bit over 600w according to its birth sheet so even more boom for your buck.
