B&O pods are just 4" woofers. Coax will be too bright / harsh. Pods are just fill anyway better to allocate funds to a $1.5-2K sub amp and sub solution that's transformative and should be #1 upgrade IMO.
I'd say if your driving super hard and fast stressing the machine your points are good OP otherwise it's overkill unless just enjoy wrenching like me.
A hipo dirt bike is high maint....
No SDS or other composition disclosure forthcoming? This tells a story in itself.
Twitchell states their forte is PVC coated fabrics... so it's the PVC that's VOC toxic off gassing sickening stench. This should never be sold as something that can be left on under the top without SDS...
Resonix worth every penny especially the black sound absorber which I applied to all plastic panel inner faces because Resonix stated to not use directly on sheet metal for which they have another product t than can handle condensation I guess.
Return on spend is extremely high and a true upgrade.
Bigger tires are an optical upgrade only unless deep sand otherwise for a functional upgrade just match tire to use case.
I did upgrade from 255/65-18 to 275/70/18 E which is better handling, winter and looks adding only 10lb per wheel.
Will likely just need a power buff on hood and fenders at least to get same shine levels. I would not remove though unless doing full HDD ppf to front end at considerable cost.
Decent sub amp like Kenwood XR1001.1 with integrated LOC or any sub amp or amplified enclosure that states works with OEM likely has internal LOC but call them first.
It's plug and play into B&O sub input wires and works perfectly. You don't want to cheap out though to get good processing...
X autohaux or similar under $40 is single layer polyester tent like material....from amazon.ca but seems like all the cheap ones with orange stripes are same mfg. I do spin off the antenna when using when no enclosed parking avail.
I ordered 3 different ones.
