Okay so im gonna be running four Sundown Audio SA-8's on a SAZ2000d. Im working on building a fiberglass box for them in my Silverado and I have heard some stuff about deadening the interior of the enclosure to gain spl and sq as well. Is this true? If so what kinds of deadener would you recomend? im guessing spray but any suggestions are helpful thanks.

If your enclosure is resonant you need to use bracing rather than trying to combat it with sound deadener.

I agree with Impious, only deadening for enclosures i've seen was with kick pods and door panels.

thanks for the tips i planned on doing some bracing just still thinking of how . and ive just heard of the deadening in competition boxes so i thought id ask

People waste money in a lot of ways What sucks is when they spread misinformation about it. Glad we can save you some dough.
