Took a lot of cutting and melting plastic with the heat gun, but I got the larger panel to fit inside the top of the cooler!

Taped the top with aluminum tape (stuff is super sticky) and got it ready to spray some expanding foam inside to try and lock the solar panel in place

Clamped in place and sprayed some foam in there! I'll see how it comes out tomorrow!

And re-glued the cheapo horn tweeters, the plastic waveguide separated from the compression driver

Crossovers in position, mid enclosures pretty much built.

The housing on the left above the crossover is for the head unit.

Total calculated internal volume before amps, subwoofer displacement and port tube subtraction is 2.456 ft ^3.

So after two 11" ports made of schedule 40 PVC and amps and driver displacement, I figure around 2.15-2.2 cubic feet
With dual 3" ports 11" long that should be roughly 36-37hz tuning. That shoud do and with only a 30hz high pass I think I'll still be fine given the wattage ill be running.

Just estimating. 2 13 watt panels and 1 10 watt. We shall see what I actually pull from them once we get some warm weather / sun here in NY.
Sorry it's 1 15 watt, 1 13 watt, 1 10 watt.

Two 35ah batteries in parallel would give me 70ah right?

Any reason not to use these two in parallel? (Same 50lbs total weight, both will fit in the duffle bag I have.....)
$141 shipped to me.

On paper, a pair will give you 70AH to full depletion.
No reason other than weight and expense not to use two.

That said, taking lead acid batteries below 50% charge (12.06 volts after a rest) shortens battery life quite a bit.
The group 27 marine lead acid batteries I used on my trike did not hold much charge after only 4 or five deep discharges.
