Underseat subwoofer in Toyota Prado with stock stereo 

Ladies and gentlemen may I present you BLAM Audio Relax MSA 25, an ultra expensive powered 10 inches under seat subwoofer. Yes it is very expensive! I know everything is made in China but why is this one so sky-high expensive!? Label says it is one designed by a guy from France and claiming to have it a French sound authenticity? I really don't know.
Anyway, here's a quick video unboxing of the BLAM Audio MSA 25 under seat mini subwoofer. Then installed into a 2020 Toyota Land Cruiser Prado by tapping signal wire to stock OEM head unit's rear speakers. Then laying out 4 gauge power cable together with the telephone like cable for subwoofer remote control. Secured the mini subwoofer into the carpet seams using cable ties. Lastly, secure the power cable by adding a fuse. I used a mini ANS-H fuse holder with 100a fuse colored purple. Bolted into battery positive post plastic cover.
