which 15" fi sub will be best to run off me amp i have the cadence a7

You didn't give us any goals, so how would we determine what is best for your application? But with that power I'd run a D2 Q with or without BP option.

Whats the rms output of that amp at 1 ohm?

what other info u need to know

Whats the rms output of that amp at 1 ohm?

1200@1 ohm an 800@2 ohm

sheer output BL, if your going sealed the Q then.

Honestly if your not set on a 15 I'd say run a pair of ssd 10's on that amount of power. Also the box size for a pair of 10's ported is generally the same size if not smaller than that of a single 15 ported. The same goes for sealed.

BTL

what other info u need to know

depends on whether or not you want useful advice, read the n00b posting rules and you will know

Yeah, X2 what ///M5 said.

What exactly do you mean by "best"?????????????

The best would def be the IB3. Just watch your gains!

The best would def be the BL; just put it in a ported box tuned to 34 htz and let it rip!

The best would by far be a nice sealed Q. Will give you some good sound and get pretty loud too.

The best would be a pair of SSD's. Less power compression and more cone area FTW!

There are so many variables. You gotta tell us what you want. You're question was the equivalent of asking what midsize car is the best?

I mean are you talking about performance, gas mileage, family friendliness, or looks? You gotta tell us what you are aiming to achieve.

Haha^^^

great way of putting it.

i mean the best fi 15" sub to run with the amp i have but thanks for all the help. i order the Fi SSD15

...>_> Shoulda Got The BL.

If he options up the SSD, it should hold if he is smart with the playing of the driver.
