Which way to fire subs

[ivey_usmc]

I have a 2018 challenger and I'm adding air ride. I have 2 10in JL w3's in sealed boxes and the only location I want to have them in is the rear quarter. Would it be better to face them up or towards each other?

Here's what I have.

Only real way to tell is to try both ways and see which way sounds best to you. There’s no absolute “this way is best”.
