dam dude, all this time talkin to us, lol, get a little string, tape it where the HU is, run it where you need it, cut it, measure it, rinse repeat

 

dam [sic], dude, no, i can't. all this time talkin to us, just answer me.

It was an easy question so I didn't think it would be a big deal if I asked and figured someone would be happy to answer. Sorry to bother you. Though if you didn't want to read, no one forced you to. Have a great day.
