Subwoofer install on Tab 400 - just a little bass to fill out the speakers in camper

Never been to pleased with sound out of the speakers from my TAB 320s so decided to make some changes on the 2024 Tab 400 I just got.  Added a Pioneer Subwoofer made for EV cars that is very efficient.  Rather simple install but you must run a remote wire from the head unit using a stereo line out converter that has a remote wire.  I used the RCA subwoofer output from Jensen RWM22 head unit.  The subwoofer fits nicely under the rear lower drawer with plenty of room.  Time will tell if I am happy with it and if this placement will work.  See pictures. 

Also added a pair of JBL 44 Clubs in the front taking out the black square speakers but that upgraded was a bit more of a pain as I didn't want to cut up the camper so had to make a small adapter plate from wood to use the same holes.
