DIY double subwoofer, car amplifier and vintage home amplifier without subwoofer output

Make a powerful subwoofer with two bass speakers at home. Use 15mm plywood and cut the sides for the subwoofer to the specified dimensions:
upper and lower x 4
Width 705 mm
Height 260 mm
dimensions:
front and rear x 2
Width 705 mm
Height 200 mm
dimensions:
side and middle x 3
Width 230 mm
Height 200 mm
Cut sleeves 50 mm long.
I use an old but working auto amplifier, it should be about 200 watts of power.
The power supply of the auto amplifier must be at least 20 - 30A to work without problems.
I also use an old working home amp, 35 watts 8 ohms. But this amp doesn't have a subwoofer output. We will use the High level to low level converter for the signal to the subwoofer that we have assembled.
bass reflex 63 mm
Two bass speakers 6.5 inch
The speakers I'm using are old and don't have good low bass, and we'll need to help them sound good.
A good configuration with excellent sound and good power, enough to satisfy even the most demanding listeners.

If someone try to add a line out converter make sure it can handle the rms out put of the amplifier to converter before using one because you will smoke the converter if it's to small or not rated for the amplifier out put you hooking it up to.😉🫡👌✌️💯
