Yeah it doesn't have to be dynomat. Nico I think I spelled that right on Amazon is decent budget friendly deadening. Around 36 sq ft for around 60 be a while since I bought any.So when you say prep the doors... Do you mean dynomat etc?
Not trying to sound dumb, it's just happening by accident lol
Think of your door as an enclosure because that's what it is. Seal off all the holes. Cover as much as you can. Inner and outer .Some foam between speakers and door panels. They sale what's called fast rings a few other car audio companies sell them too. I just use a garage door foam type seal for a lot less.
If you don't you will have very little bass response kinda important without a sub wouldn't ya think
