And looks nice. It's not gunna be a record breaker or even close I just wanted some help thank you for showing you are all douchebags

The truth of the matter is, there is no way to fit a properly built bandpass for four 12's in a trunk. That's the advice from the guys here, who have been around the block and seen all of the impossible ideas.

The issues is still space. I get that you want to use four 12's, but take a look at some of the best and loudest trunk builds on the forum, you might reconsider.

Don't get to worked up about it. I wanted to do 2 18's in a c pillar in my car. I was told it wouldn't be possible. I took some measurements, and guess what, It wasn't. ya some of us can be dicks but most of the time we know best and mean well. now if you want to experiment with it and see how it turns out then do it. just be aware it may not work out too well. im still doing a c pillar even though some say I shouldn't. but I know that it may, or may not work out. its all in good fun. the worst that happens is I have to rebuild it. do what you wanna do. just keep in mind it may or may not turn out as you planned.

^Small means nothing. Alot of the time the "smaller" subs, if you are talking about motor size, actually require larger enclosures. That being said I know nothing about your subs.

However, I disagree with most of the guys in here. If those subs do have a reasonable sealed resonance in 1 cube each (45-55hz ish. I think a lower ratio trunk 4th would be a great build. Alot of times people get caught up in what is louder not necessarily what is louder across a wide bandwidth. Do you know how to design and build a proper 4th order?
