There is a substancial difference for Amplifier 150-200 Watt RMS into 4 Ohm
and the same into 8 Ohm.
But if nothing else is told, we will assume you talk normal 8 Ohm.

Subwoofer/Bass amplifiers have some special features.
And should be able to output heavy current peaks.
It is always better to use a dedicated Bass amplifier for subwoofers.

What is YoYo's intention?
Do you want to build a 150W into 6r0 amplifier for your own use?
or
do you want us to supply all the information so that you can go into production and make a profit without any capability to service your customers?

Your blog shows 2955/3055 for outputs. Do you have the datasheet?
Have you any information about your output devices?
