Ported design for 4-Polk SR124DVC

[educatedink 10+ year member]

I don't expect anything for free. I'll be more than happy to make a "donation" to someone's beer fund. However, if you wish to be generous, I won't complain.

Running 4-Polk 124DVC with 2-Polk PA1200.1 (in series), somewhat underpowered I know.

I'm putting these in a QC Dodge Ram, currently equipped with a 10cu coffin for 4-12L7 4ohms, each with a Kicker zx750.1. So, space isn't an issue. I prefer to limit the length to 56 inches!

Maybe downfire with ports to the side? I'm open on this.

Here some of the specs via Polk's website:

each sub requires 1.5 cu ft + 0.14 displacement

Fs 30hz

Qts 0.55

Qes 0.6

Qms 8.0

Vas 53L

Xmax Linear 0.64in (16.25mm)

Re 7.0 Ohms series

1.75 Ohms parallel

Mms 183g

Cms 150 um/N

BI 19T-m series

9.3T-m parallel

Sd 499 sq cm

77.35 sq in

If you're interested in the Kicker amps/subs, let me know.
