When the spring comes, I always want to build something new.. I was thinking glass for a while, but I have no experience with it and I'm unsure of the sq from a glass enclosure. I know I'm not going to achieve any large amount of spl plus this is for a daily driver. Anyways, I have a 2dr sunfire with the following setup

-kenwood kac7203 amp [170 Watts x 2 Channels @ 4 Ohms/250 Watts x 2 Channels @ 2 Ohms/ 500 watts x 1 Channel @ 4 Ohms (Bridged) ]
-2 kfc2511 10" 4ohm subs (350w rms)

I can get the dimensions of the trunk if needed. But basically I am looking for someone to give me some design ideas for my setup, because I know very little about tuning/ports.

Sub Spec Sheet

Just hoping someone will play around with the idea and come up with something. Thanks

 

I might be totally off but I would suggest approximately 3 cubes @34hz. I have a Cavalier sedan and I found that 34hz was nice for sounding good and still getting loud when you wanted it to.

That amp isn't a good choice as far as 4ohm SVC subs go, you'll only get 125rms(assuming it actually does 250rms x2 @2ohm) to each sub.

If you're looking for nice simple, clean sounding bass, a sealed box would treat you well also.

 

I understand, but I have to work with what I have. Currently i have 2 seperate 1.25 ft² ported boxes. I went with seperate boxs because of the small opening of the trunk. 3 ft² @ 34hz ... Where can i find a design for a setup like this? I have tried on the port calculator site, and I dont completely understand the information it gives me. 1 10" driver with an Xmas of 6.9mm, @ 34hz ..Minimum diameter = 3.46" and min area = 9.42" . Which means I need a port at least 3.46 " ... so when i plug that into the length calculator ( 1 round port with a enclosure volume of 1.5 ft² @ 34hz and 3.5" diameter ) the length comes to 12.39" . Does that mean to achieve 34hz in a 1.5 ft² i will need a port 3.5" diameter x 12.39" long ? Does placement of the port matter? Does the type of port material matter ? I know this is all probably common sense to you but thanks for taking the time to help me.

 

Here's one for 33hz:

Also 35hz:

Either or should sound good IMO.

 

the actual dimensions of the box are irrelevant of the tuning no ? its just the port height width depth ?

 

As far as I know, tuning has to do with airspace, port area and port length. So yes, might be wrong though.

 

ahh ok. Do you build furious.. I'm living in st johns now. Maybe you can give me a price lol.

 

I've built a few boxes. If you want it to look amazing, don't ask me haha. The boxes I have built, while not looking the best, have performed well.
