Well, I can't find any audiobahns that are 4 ohm svc, or 2 ohm dvc... so nun of them will work with my amp. I found some Kicker l7's that I could prob afford in a few week's:-) but theres one problem. The reason they are so cheap is they have been factory renewed. The store is a authorised dealer... so they have a 90 day waranty. Is it still a bad idea to get factory renewed stuff? My second question is... I can get a 10 inch l7 for $139, and it is the 04 mottle, or the 12l7 for $129... but it is the 02 mottle. What should I go with?

a different sub...lol... take advantage of a 15 atlas for 105$ in a ported box ive heard they can reach 141 db i doubt one L7 will do any better. and they are much more efficient with 250-300 watt rms i know your amp is probably too powerful but then you can sell that and ghet a less powerful one....

...just a thought ...

..oh and how much to DD lower end subs cost? i have no idea but i bet they are great

Lol, no way I'm selling my amp!:-) I really don't want a 15 either... and the 12l7 are rated at 750 rms, and my amp is 800 rms.
I just don't want to buy something that is already crap! I know that solo's have been known for crapping out, and these have already been renewed... wich I'm guessing that they have already taken a crap on someone else!

The amp is the RF p8002, it's only stable at 4 ohms bridged. 800 watts rms x 1 at 4 ohms

but this thread is about SPL so if you want SPL go with those. but they really arnt square, more like rectangular I think they have less cone area than a circular one.

Also, do you think the box you was talking about in my other thread would work? The one where it was ported, but you could make it sealed too?

at those measurements ,inus 1.5 inches l x w x h youd be at 5.22 cf before the sub (3.5 ft wide)

wed be in business and would go slightly smaller than the 3.5 wide to match up to the 4.75 cf after displacements for the sub and ports

no but ill tell you this with about 2 cf ported in a sledgehammer mtx box a friend of mine hits in the 140s with an audiobahn 2400 watt amp with two 12 l7s but that amp is over rated and your gonna gain 5 db with spl port so youll have about a -1 db avantage on him with your one twelve vs his two twelves and half his power so the 140 is quite possible

Hum... I was looking at the spec's for the 04 mottle l7, it recomends for ported 1.75 - 3.25 cubic FT. Granted the one I'm looking at is the 02 mottle... there shouldn't be any difference in the air space requirment's.
P.s, could you post the measurments of the box it will need?
Hight, from the seat going to the roof, width, from the start of the seat, to the back, and the length, across the seat. Thanks for all you're help.

BTW, wouldn't a 4 cubic ft box be a little big for a sealed box? I wouldn't think the ported box with interchangable ports would work... I mean, how much sq can you get with 4 cubic FT?:-)

well lets assume .25 that puts us at 5.00 cf which is 18 x 15 x 40.5 5.02 cf

Ya, I'm just going to measure to see if my seat can handle 18 in tall, 15 in deep, and 40.5 in long.
Just wondering, where would the ports go?

Ok.
So, how does the interchangable ports work? Is ther some like tuned to 35hz, and the spl tuned like 45/50hz?

yes your daily would be tuned to 34 hz and the spl one would be tuned to 46 hz and peak at 50 hz

youd have two 4 inch ports 9.25 inches deep for the 34 hz port tune and two 4 inch ports 3.75 inches long for your 46 hz port tune

I just thought of another question... I told you I don't know anything about boxes!:-)
I know that the back is supposed to have a slope so the sound waves don't cancel out or something... but how much of a slope will I need? The bottom of the box will be 18 in, does that mean the top will only be like 16?

this has nothing to do with what you ppl are tlking about but i have a problem on where to set the gain on the amp when the amp's gain is from 150mv-4v but my HU is 5v?

Anon, I'm not for sure on how to set the gain on amps, but you are supposed to match it with you're head units output or something like that... so set at 5 I'm guessing.

Sean, we have a little problem, I can't go 15 deep, 13.5 is about it... I might could cram 14 in, but it would be hard. Everything else I think should work.

if you can give me 13.75 id be happy that would give us 3inches from the back of the box but if not its fine........18 x 13.75 x 44.5 = 5.029 cf can you do this or is it a problem?
