Help! Rockford sub setup and box design


Recommended Posts

A four door blazer has the following dimensions. Roughly. 38 x 30 x 25 including seat lean. The depth shrink quickly after 17 high due to the angle of the rear glass. if you at or bellow 17 you have as much as 35 deep. Ie.38w x 17h x 35d

lower tuning is just hard. I was surprised how loud 145 sounds at 35hz, and how quiet 145 sounds at 50hz.

^^this man is correct lol. Are you dead set on Rockford?? I would check out the SA-12s. The results have been proven on how beefy these woofers are. Or do something like 8 8s...that would be awsome

a single btl would require you to upgrade your alternator which would cost you some money.

Why would the type of sub require stiffer electrical? Of course the BTL has a higher rms but that does not mean he needs to run it at higher power. And a new alternator for 2000 isn't required in my opinion.

To the OP, BTLs are beasts for sure but if you can do two 18s do it. More cone area and closer to your budget.

Tell me...does this smell like chloroform to you?
