This Car Audio Amplifier to run an older 8 inch pioneer sub in a bandpass box . This delivers as expected. Subwoofer sounds perfect. I tried to run it off the stock deck using the high pass but it wouldnt turn on. I took a jumper wire and touched the remote to the positive and it fired up immediately. Dont expect any help from Boss via their phone number on the box. I waited for 20 minutes before I just decided to hang up and just pick up a new deck. It sounds great.

That this amp would not do a good job pushing a subwoofer is that it only has a "Subwoofer level control". This is not to be mistaken for a crossover/low pass filter. You need some form of crossover to keep it from sending high frequencies to the speaker.

Circuit amplifier "High Power HiFi Power Amplifier With MOSFET" is capable of giving the output power to the load speakers 240Watt and 380Watt 8Ohm to load 4Ohm speakers.

Voltage source to a series of power amplifiers "High Power HiFi Power Amplifier With MOSFET" This is a CT 25V 50V 25V to 50V CT of transformer CT. In making this power amplifier needs to be installed heatsinks on the power amplifier (MOSFET) in order to avoid excessive heat. The series of power supply to power amplifer can use the transformer 5A-20A and 35A mounted diode bridge and capacitors for a minimum of 2x 10.000uF electrolit. Details for the power amplifier circuit can be seen in the following figure.
