Stickying this ...

Very worthwhile to go through and see all of the time and effort put into those vehicles.

some are just amazing, plus that there is proof the SOloX 10 and 12 are coming

Can someone explain something to me?I don't see how stock can hit 157.x with only a 12.. and on the score sheet I saw a 157.x and all these high numbers in stock, almost everyone was hitting over 155 that was in first or second.

Am I missing something, or are they just super loud?

Thanks for the explanation and cool pics!

Sorry if someone gets mad because this is off topic.

This is USACi - requirements are for the car to not be modified. Sport utilites can have the entire cargo area for an enclosure, provided it doesn't go above the window line or back seat, whichever is lower. No extra batteries, and stock alternator.

Gives you QUITE a bit of room for flexibility.

They are loud too... It is world finals after all. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Oh, ok thanks.

Wasn't DB Drag's stock 0-150 like..155.x db?

I mean 157 with a 10 or 12 in stock is just...skjdh..crx?

Sorry,it's just hard to grasp the massivness of the wang.

Ahh, but drag uses different measurement systems also..

That 157 is about a 150-153 on drags new sensors... And they don't have to have just a 10" or 12" in basic stock. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Oh.well, thats a big difference.

Aren't the classes determined through woofer size, because it said 0-150, 150-300,301-600, for SPL?

That's USACi's divisions - it's based on total amplifier power @ 12v @ 4 ohm with all channels operational.

OOOHH so I could have 4 35.1's that do about 35@4ohms and still be in the 0-150 stock class?

Thats a really wierd way to classify things..

SO the 0-150 is the watts?or cone area...sorry, I learn slow. //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

Correct, you could have 4 of them and be dictated in the 0-150 class, stock would depend on your overall install though.

I think Basic stock also has an amplifier limit on it, I'd have to dig out my rule book to be totally sure though. I'm not too up to date on SPL rules. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

The 0-150 is purely power class, cone area has no bearing in usaci at all.

Ohhh ok! Thanks for the explanation.

I don't like their rules..
