I installed the amp with a Lightning Audio install kit. I soldered in to the rear speaker wires for connection to the high inputs on the amp, and soldered in to the accessory wire leading to the head unit for remote on. The low pass filter works fine. Remote on works fine. There is a slight pop on power up with remote, but I imagine that is to be expected. I was disappointed to learn it’s not bridgeable, but it works fine on one 100W channel. I haven’t driven it hard on my 12" sub, but IMO there’s no need. It does a great job filling in the lows that my factory stereo couldn’t reach. The price is excellent for the versatility of high and low inputs, low pass filter, and dual channels. I was also happy with the compact size, as it fits easily under one side of the driver’s seat without risk of getting kicked.
