4 12s replacing my of back seat

[SnowDrifter]

Re-do the box. More port area and a narrower port

What subs and how much power?

[TrunkMuzik]

phoenix gold 300rms a piece for now

[SnowDrifter]

More efficient box, better subs, more power, you should be in business. I think you will be happier with that than a box in the back seats.

I think you can do better with 2 12s to be honest. Since it doesn't look like you can fit a proper box for 3 or 4 and less subs in a better box > more subs in a subpar box

Who designed that? The port is choking to death.

2 'better' 12's with a WAAAAYYYYY better box would make you happier than the back seat box idea. And you'll still have trunk space.

[TrunkMuzik]

Don't have money to go out and get different subs and amps. I already have 4 phoenix golds. They arnt too bad either for how cheap they are

and I used a box calculator for it and it turned out shitty. hats why I said I suck at designing boxes and wanted help with a box design

[OrionStang]

1. What amp(s) do you have?

2. Sell the current subs.

3. Use those funds to buy two better subs.

4. Once you have better subs, ask for help here on a box design that bangs.

[TrunkMuzik]

if buy these

I really want sundowns

and my amp does close to 1200rms at 1 ohm so ill just stick with it either way

[OrionStang]

So 2 Sa-12's on your current amp = winning.

[TrunkMuzik]

you really think they would be louder?

what kind of box desighn would be best? would the port still be back or facing through the back seats

[OrionStang]

Subs and port back. I'd recommend a center port.

Do your seats fold down?
