Chrysler 300 build questions

[screwedup.ant]

I have 2 soundqubed HDS3.2 15s on a taramps 3k in a 2019 Chrysler 300. Box is ported through rear deck subs firing in cabin about 8 cube box. Should I upgrade to bigger 15s and amp or buy 2 more of the HDS3.2 and make a wall setup of 4 15s, what would be louder or the better option

You can do a number of thing before considering a wall, first is checking your box specs, do you know what is your port area and tuning?

 

Already can see you are not sealed off, you can gain output doing so.

 

You can gain output by using subs that work in smaller net volume. SoundQuberd usually need larger net volume to work well.

 

You can run more powerful subs and amps to considerably increasing your output.

Port is on smaller side 7 inches tuned at 30 hz , and how would I seal the trunk off?

Not sure what you mean by 7 inches but lets see, a round port 7 inches in diameter would have a port area of 39 square inches, a 7x7 square port would have a port area of 49 square inches, the manufacturer would want 128 square inches (like 18.2" x 7" port area) with an 8 cubic feet box for those two subs so right there you have brutal output loss.

 

Sealing off is making your trunk FULLY airtight from the cabin, stopping air from flowing into your trunk and back effectively reduces you your cabin volume lifting up significantly your low frequencies. A proper seal off is a lot of work to get right.

Unless u built that box inside the trunk there's no way u have 8 cu ft
