On the DB692 speakers, what is the hole center to center measurement for length and width?

Got a pair of DB692, would like to know if you can provide with the cut-in template, I will install them in my 2012 Street Glide, but in the flat part, not the corner. Can you guys help me? Thanks

Asked by: Fabian
Hi Fabian, Unfortunately, I do not have a template available for the DB692. The best I can offer is a copy of the manual: https://www.polkaudio.com/-/media/files/documentmaster/polk-us/us/db__speaker_online_manual_24072021.pdf

I have the DB692and want to verify which wire lead is (+) and which is (-)? I have two(2) gray wires and one has a black stripe. Just want to make sure I connect correctly.
