Thanks

can anyone tell me how much sealed volume do I need per sa18 if I plan to build a fourth order wall.

I don't have any Meters btw

HU starts at 50 and ends at 120 I believe

Ok so turn off low pass on head unit, check but set low pass on amp to where? Starts at 35

Thanks got it, now how do I handle the low pass filters on my head unit and amp

Not asking where to set my gain or bass boost. I want to know what the phase is for and where to set it and my box is tuned to 32 hz with 2 sundown X 15's so where do I set low pass and subsonic. Also where do I set the low pass on my radio.

I bought these two subs as well I'm trying to get some information about a box. Except I'm going to be running them on a S a Z 3500

I have a saz-3500...should I go with two x 15 sundowns in a small box or two zv4 12 sundowns in a big box I'm so torn here between the two. I'm told sundown is so conservatively rated that's why I say a small box for the 15's and a big box for the 12's I need help choosing plz

These would be (X 18's) or (X 15's) by the way.

I have a small size SUV, and Im trying to run two 18" subs that need a (xx) minimum volume in a standard vented box. To achieve this I need to face subs up and vent up. Now I've always faced subs and vent towards rear. And a lot of people keep telling me to face subs up and vent towards rear. What I want to know is, is it that much of a difference. And if there is that much of a difference what about compared to two 15" subs faced up vent towards rear. As this I can achieve. (two 18" subs, subs and vent faced up) -VS- (two 15" subs, subs faced up vent towards rear)??

Thanks for your suggestion. And yeah I threw the .5 ohm or 1 ohm question in there just to see what people would say.

I would like to know what would you do in my situation. I have a 2006 Chevrolet trailblazer LS not extended daily driver, a Mechman 250A, and enough XS power batteries to cover 5K watts. I just bought a Sundown audio saz-3500d and I would like to know what sundown (series, size, quantity) woofers would you use and would you wire the amp at .5 ohm or 1 ohm. And why? Also how would you set up your box without sacrificing the backseat. (nothing in detail about the box just a general idea of how you would set it up) And why?
