Need some more bass!

[Blazerguy]

Hi, I have a 1999 blazer with a single 12 Fi Q powered by a cadence zrs-7000d which is running at about 1300 rms at 1 ohm. The Fi Q is in a 2.2cuft L-Ported box tuned to about 32 hz. I really like this sub woofer but i am looking for more output. The only problem is my box can only be 29" wide, and about 3cuft. I am looking at keeping my amp and getting two 12's that are about 600 rms each, how significant would the increase in output be of two 12's at 600 rms a piece compaired to my one 12 at 1300rms? Even maybe a single 15? I have been looking at the SA-12 and the DC level 3 12

I would just like some suggestions on how i could get the most output with the space and the power that i have.

Thank you!

Did you not read? I already have a sub, I am wanting more output.

Hahaha I know I was just giving you some sh*t man... Welcome to the site btw... If you have 3 cubes of space I would probably go with a single 15

How much more output would i get with a single 15? I know on sundowns website is says 1.5cuft for a ported 12, or all the way down to 1cuft for spl oriented applications.

If you give a good 15 1000 watts from your amp at 1 ohm and give it all the space you can get you will get much more output... I kinda wanna go with a 15 after installing a few at work but I decided to make it a personal goal to see how far I can take a 12

Look into aero ports to save some internal space and if you had some more power the SA12's would love it, but a single 15" would get down as well

Heck a pair of SA10's would get down in that size box

Ok so i have rethought my box, i could be able to take out my spare tire and make the box about 5^3. Also to get the output i want im starting to thing i am gonna need more power. I could by another zrs-7000d to get another 1300 watts, or sell mine and go with a single larger amp, like up to about 3k. But if i was to run about 3k would upgrading my alt to a 250 amp alt be enough to support the electrical? I have a 800cca AC Delco professional battery up front, should be equal to a optima yellow top. So, what could i do with about 5^3 and 3k watts to get the most output in the back of a blazer. Thank you!
