Jalat, what the heck is the car resonance and does it have to be considered in all these calculations? Is it such a big deal?

Some reading to do for myself education.....

 

Ok, Jalat - You are the MAN :-) Here are the final bits of info to assist you :-) to assist me to make a good sounding enclosure. For some unexplained reason I tend to "believe" in lower frequency say @ 34-36Kz (guess I think it gives moredeeper bass). Here is the reviewed/detailed list of my listening preferences:

A
1. Rap (White Girl, Get Down, Boom-Boom-Boom) - 50%
2. Pop (Britney, Beyonce,Lady Gaga :-)) - 25%
3. Techno/House/Club - 15%
4. Country - 10%

B
I am not familiar with all meanings for SQL and SPL, but I know for a fact what I want. I want a deep chest bass, as I've said the one you feel not hear. I could care less to impress girls/neighboors by being heard 3 blocks away. I need the deep bass IN the car. Please tune the enclosure accordingly :-)

C
My width clearance in the trunk of Impala is 32 inches. Doable?

D
Sub specifications here Solo-Baric L7 | KICKER

There is anything else I need to provide you before the blue print could be produced?

Thank you...

 

i'll have something sketched up for you tommorow
