Enclosure help with 2 fi btl 15's

[bigp0]

Was hoping to get help on a box design for 2 fi btl 15's 2ohm for a 2 door tahoe. Will be mainly rap and r & b. I believe subs up port back is the most popular for most daily setups i've come across in this suv. I want to do port along bottom as long as it performs ok.. Dimensions are 48w x 28d x 18h. Will be using 2 rf bd2500cp's to push these and electrical is adequate. Thanks in advance. i

100+ views with no response? Ok, how about opinions on 8^3 vb and 33hz tune with 108in2 of port. Thanks.

Do you know how to gain match?

[bigp0]

Thanks for the reply Joe. I do know how to gain match but are you referring to amps to source or amps output to subs?

[Efreakingt]

I think what he means is matching amps to subs. If you drop 2 subs in a shared space and run 2 amps then both amps need to be pushing the subs identically to make it work right.

[bigp0]

Fig as much. Just wanted to be clear.

[Joe X]

Ok so I checked and it looks like the amps are strappable (please verify) so that you won't be needing a gain matching procedure, ill seek to get something for you later today.

[bigp0]

Yes they will be ran strapped(bd sync)@ 2ohms.

BTLs are SPL oriented drivers, here are the theoretical response and cone displacement:

Box is 4 net per driver with a 35Hz tuning.

Theoretical in.car response:
