question for scott about Fi/SX 12

Hey Scott,

Are the specs the same on my subwoofer, power handling wise? Is it still 1000 rms or is it more now? I'm trying to figure out the right voltage so I can set the gains on my amp with my DMM. Oh and the shirt is awesome, thanks alot for the shirt and the stickers.

specs and everything are the same..unless you paid for other stuff to be done then it's pretty much the same as a stock SX

Just curious why your setting your amp by the output voltage? The only reason you should be doing that is if you are gain matching multiple amps..

You should be matching input voltage on the RCA's to the RCA voltage on the deck with the gain on the amplifier, not output voltage.

I'm just following the instructions from the HOW TO on gain settings. Im just trying not to clip the new sub. I think may be what damaged it before you guys fixed it.

[NDMstang65 403]

Probably because that's how you set the gain .

The only problem with that theory is that music is totally dynamic..

Gains are meant to match input voltage on the rca leads. Not output voltage going to a constantly changing impedence.

By that theory you could have the gain wide open..and still not have a desired voltage (whatever that may be) that your looking for.

You don't clip output, you clip input that is then amplified into the output stage of the amp...

well Ive been playing with it all day and I think I got it about right. I can adjust my sub levels from my cd player all the way up with no clipping and its still really loud so I think that should do the trick. Ill be sure to post my vid and pics of it inside and outside the box this weekend. Thanks for the info Nick.

k cool. my friend just got 2 12 x's but hes still waitin to build the box and i wanna see how they sound.

I guess i enjoy watchin videos of subs especially Fi

finally finished my masterpeice today hah:

Well a video of my sub wouldnt help you since its not an X. I got my RE SX12 reconed by Fi. So actually mine is around the equivalent of your Q.
