I just got a 1998 blazer (4 door) and transferred over my Sundown Audio SAE-1200D and 12" BL from my 99 grand am.

The box is 2.5 cuft AFTER sub and port dislacement, tuned around 32-34hz (can't remember exactly off the top of my head)

I have upgraded the BIG 3 with 1/0ga wire, ran conduit along the frame rail with 1/0ga to the amp.

In my grand am I LOVED it, but now in the blazer it seems to be lacking... not sure what exactly, but it doesn't seem to rattle my noggin like it did in the grand am.

My question is should I look at building another enclosure that would work better for the blazer? If so, how many cuft? tuned to? how should the sub and port face?

Or is the blazer just that much more airspace compared to the car that it is not going to be the same?

Any and all suggestions are appreciated. Thanks in advance

And before I forget... right now the sub and port are on the same side facing the rear (enclosure is against the backseat)

:beer: for everyone that helps me

Edit: one last thing... this is strictly a daily driver and will NEVER see a mic

Try putting the port 6-12 inches from the rear gate. the closer the box is to the middle of the car the more cancellation there is.

and if you build a new box try sub up port back

in the morning i will try moving the box closer to the rear gate... see what happens.

B7L BL4Z3R... sub up/port back.... crx style box right? should i stick with the tuning frequency and cuft i have now or switch that up also?

2.5@32hz. would be good

Ignore him.....

Reason it doesn't "rattle your noggin" as much is the massive increase in airspace from a Grand Am to a Blazer. You simply won't be able to get the same "noggin rattling" bass without some more cone area and power.

Although you could do an SPL box tuned to high 50's........ that would rattle you a little. But since it's for music, and tuned low...... best bet is more power and more cone area.
