Interesting video. You can see why I struggle with OP-amp theory. Only understand part of it. Back to the speakers. How are the speakers connected to the amplifier's? With incorrect wiring, then you may be placing a 2 ohm load on the amp. This will present as a dead short to the amplifier protection circuit, and shut down the amp.

Assuming you want to join the Doctor Who Society of Canada, which is your local chapter, most venues, parking is not an issue, such as in malls and arenas, we are allowed to park typically free. Bigger events becomes a team effort to sort things out. Events you need to “worry about” are Montreal and Toronto, most other venues we can just park. If you buy a trailer, I highly recommend a closed one, preferably with a ramp. and yes, more expensive to park with a trailer at areas that charge for parking.  

This build is taking forever 🤪   I’ve been poking at it on and off Sufficient progress to report now regarding the skinning of the inside of the skirt.    Not sure if anyone has done this before but here is what I did.  Refinement on “how to” are most welcomed as I need to do another one for the group.  Here is what the open skirt looked like with the facing of the skirt in and fibreglassed.   Easiest thing I taught to install the inside frame and get exact measurements of the panels was to make an inside frame for each panel.  Muked around to figure the correct angels and proceeded to cut each piece and held them in place friction just to get everything sorted.  mark each piece with a corresponding letter and top bottom.  once the frame was all cut, I glued the frame together and once dry, drilled a hole in each end to place a dowel.  This provided more rigidity to the frame when manipulating it.  to ease with sliding in the dowel and applying glue, I pinched each dowel slightly with a set of vice grip     here you see the before and after with a bit of sanding to level everything out.    test fit it all again and everything fits 🤗   I then traced all the frames on some 1/8 ply and cut everything. In my haste I did not take pictures when cutting I overlapped (cut bigger all the prices) test fit and adjusted cuts as required.  I’ll admit there was not a lot of measuring and a lot of eyeballing.    I left a small overlap for the top and bottom and once all panels were screwed in with hex wood button head screws (2.5). Once I was happy with the fit. I nailed everything in place to ensure no more play in the fit. I traced a line from the outside on the top bottom extra material. Cut with straight edge and circular saw leaving a 1 mm overlap which I sanded   Some minor touch up to do and add a few screws but sufficiently done to allow me to move to the next part.    skinning inside of neck and shoulders.    But that will be for another day
