New to the Fi game and want some opinions

Well, we just slopped together a set up for this years nopi nationals in atlanta. It was 3 kicker CVR 12's in a partitioned sealed box feeding each sub 2.4 square feet, and also 3 kicker CVR 10's in a partitioned box feeding each about 1.6 square feet. They were stacked and put in the back of a 98' Durango no extra battery, not even another cap. Powered it by 2 Crunch Powerzone 1000W 2 channels.

We ran the stock USAC 1801-3001 class, and did well. Hit 141.2SPL at 56Hz beating several guys running memphis 15's.

Regardless, we are gearing up for next year to be much bigger and louder. This year's set up was built in 2 days with subs from various cars just thrown together into one big build.

I'm debating between running Q's or BL's.

We want daily listening possible and want it to still handle music. We want the 150SPL ballpark. Do you think 3 Q 10's and 3 Q 12's could lay down that kind of power?

ugh...

Use the same size.

honestly you should be able to figure out how to do it with a single or dual 12 setup. your system is riddled with no no's that should be fixed before you spend any more time on it, personaly i'm surprised your competing with it.

Using 10s and 12's really helped our CVR's catch everything, the 12's dont handle higher ranges well. Especially with the airspace we gave them.

The system is getting a complete strip down and rebuild.

Another thing...We inverted our CRV's for cooling because they were cooking themselves mounted normally. Once inverted we could run them hard all day without any problems.

If you were to run the BL with the P chamfer option, would inverting help the heat or just lose efficiency?

Using 10 & 12's did NOTHING at all for you, well nothing positive that is. 141 with that much power isn't even loud.

Hitting 150 is easily possible with either Fi setup, but it will really come down to your box designing and building prowess.

Doubt it , subs don't make power j/p Have you given any thought to simply running what ever in a ported enclosure ?

yea people always say hat running 10s&10s will give u more cuz the 10s hit notes that 12s cant lol thats not true when u do run diffrent size subs u kinda have a wave conflict it would seen like to me like the 12 sound would cover or muffel the 10 cuz the 10" waves arent as big or somthing lol

The sound wave of a 50hz tone is just as long coming from a 10 inch diameter driver as it is from a bajillion mile diameter driver . With multiple size subs you usually run into cancellation issues which will reduce your over all output

[Fi Car Audio 64]

Id stick to a single driver size. It reduces issues with cancellation and is easier overall to setup. I would go ported as well. If you are ported, the BLs with some power would be a solid choice. The cooling will help things for long term listening. The port will keep things from heating up like a Holly Hobby Easy Bake Oven Lil Jon can tell you how hot his sealed subs get... with visual waves of heat coming off things. Sealed for too long simply makes ovens inside the box. Inverted will help though.

Thanks,

Scott

lol ramos thanx lol i was trying to think of a better way to put it but u got it

Thanks for all the input, I'm for the most part new to everything. I'm working as an installer now, and I like to think I'm pretty good for the work I've done so far but I'm looking to kick it up a bit and get into the bigger set ups.

Maybe a 4 18" BTL set up will meet our needs. Could 4 Hifonics Brutus 2006D amps power something like that?

I know its recommended 5-8 Sq feet for a 18" BTL, but what would you guys recommend 4 sit in?
