With regards on using the filters on your amp or HU. You neither use one of them since your speakers comes with passive filters already. Just turn off the HPF on the HU and set the the filters of the amp to off or all pass. If the amplifier does not come with the option of setting the filters to off or all pass, leave the settings to HPF.
I'm not too sure about it being more heat resistant. After all, it's not as if you're reflecting the actual rays of the sun when it's inside the door pane and I believe the peeps at DIYMA looks for it more like a marketing gimmick more than anything else.

However, it does look more clean and if aesthetics is the basis of the purchase I think it warrants the added cost.
