Sub question

My latest problem in dealing with my system.. I got every thing working nothing cuts out now but my sub has no real punch to it the thing just bassicly vibrates every thing. Its a Pioneer 450watt 10" sub in the el cheapo walmart box (im replacing soon i hope) powerd by a RockfordFosgate 501x amp. Would changing the box to some thing better remove all the vibrating and give me some real punch or is it the sub. My friend has the same box but has a Jensen 450watt 10"sub and it has alittle punch but doesnt vibrate the whole truck.

Any suggestions on what to do

Yes Change that piece of crap box. get one made of 3/4 inch mdf wood, the box is everything,(i would probaly get another sub to.

OK can you recomend a box and sub im thinking this sub http://www.cardomain.com/item/ROCP110S4 but still need a box

If i build my own would a 1'wx1'Lx'1h work that would give me 1cubic foot of airspace (yes i know to take into acount for material width)

Don't buy that sub that your thinkin about. I've looked at them and thought about them myself and they ain't worth what your putting into them. If you don't wanna spend the big money for a good Rockford sub(power stage 1) them atleast up it to the stage 2 or 3 or the HX2.

If i build my own would a 1'wx1'Lx'1h work that would give me 1cubic foot of airspace (yes i know to take into acount for material width)

Remember to take into account the sub's displacement. So for a 1cf box, you often have to build a 1.15 or 1.2cf box, and then the sub's suspension/motor/basket takes away about .2cf to bring the box size back down to what you want.

And personally I would stop looking at the best buy/circuit city subs and go for something a little better. If you don't like the way yours sounds, why move to another brand in the same class that isn't any better instead of actually upgrading?

ok sr20de4evr whats a good sub thats not gonna breake me

How much do you want to spend?

not more than $200

how about this
http://www.cardomain.com/item/ROCP210S4

for a sub and a box or just sub?

and isn't that amp a 4ch? How do you have it wired to the sub?

how about this http://www.cardomain.com/item/IDSID12V3D4

The new punches are worse than the old ones IMO

I personally like Audiobahn. They hit hard and sound good. The Alum12 are my favorites.

Haibane that looks good to me any others you might suggest?

sr20de4evr if i can find a box online thats not to expensive and will fit in the back of my cab ill get it if not i have to build my own. but what would you suggest for sub and box. And yes its a 4 channel amp i have it bridged on the rear channel with it set on low pass so it only gets low, on another note i turned down the gain on it and it sounds alot better i think i had it almost at full

yeah i hate the new rockford products. they all look like shit. too much plastic/chrome. get back to building good subs, not fucking "impress the stupid chicks" stuff

Haibane on that sub you posted why are there 4 conections on it?.

it is a dual 4 ohm... hmm that wont work with a 4 channel though

http://www.cardomain.com/item/IDSID12V3D2 there

there

Why do people bother me with posting and even recommending an audiobahn driver FOR SQ? ARE YOU MAD???!?!? Ok, so you need to listen to some real speakers obviously, but it is understandable. We should really put a sticky up about audiobahns in the car audio forum

http://www.cardomain.com/item/IDSID12V3D2 there



he can get an IDQ12 and still stay under the $200 limit instead, just get it at www.sounddomain.com and pricematch www.speedsound.com

Ov2 is good too, or should be good, it isn't out yet so it's hard to say

so this is the sub you all recomend http://www.cardomain.com/item/IDSID12V3D2.
Any boxes you might recomend or tips on building my own

this was the one sr2 recommended price matched though http://www.cardomain.com/item/IDSIDQ12D2V2

Ok from the reviews people are giving those sub they need to be at their RMS rating how I have my set up now im only geting 130rms on the rear channel i think thats right.. I have it bridged on the rear channel and i think the amp is 64x4 at 4ohm is that gonna be to low for that sub?

OK correction bridged RMS for that amp is 250rms so will that be enough for those subs? also im a little tight on space in the back of my cab would i still get the same sound from one of those subs in the 10" version

250rms will be great for an IDQ10

ok Id like to go with the 10" version just to save space so im thinking one of these two
http://www.cardomain.com/item/IDSIDQ10D4V2
or
http://www.cardomain.com/item/IDSID10V3D4

Now whats the difference between the two Ive read the reviews on both and every one says they are both bad ass subs as far as i can tell from just the specs is that the IDQ10 can be used in a smaller box but what can you all tell me

What do you think of the Q logic boxes? they have to be better than my walmart box

It would be these and these

ah ok so i want the 2ohm version

dual 2 ohm, wire it in series

so if i get the dual 2 ohm sub i hook up my wires like normal then another wire from + to - on the other set of connectors? and the on the amp bridge it like i have it currently?

You hook the + on one voice coil to the + on the amp, and the - on the other voice coil to the - on the amp. Then you take a piece of wire maybe 8" long (however long you need to run all the way across the sub) and connect the 2 unused terminals together. The way you described it sounded right IF you left the wires in the same place and rotated the sub 90 degrees.

well i just found out today that at the end of the month im gonna be geting a bounus so i will be using it to buy that sub.

DO NOT BUY Q LOGIC BOXES!!!

first, do the ported box, you'll get alot more out of the sub.
second, never buy a ported box that doesnt have the port facing the same way as the sub. the box is extremely important to how it sounds, you can loose major spl and sq from a box. I helped a friend out that had a 12 in a q logic 1.25 ported box. it was a good sub, but it didn't hit at all. he was mad, we made a custom box according to manufacture specs, and it was muuuuuuuuuch louder, 2.0 cu ft, and the port on the same wall as the driver, not like the Q logics, and he was alot happier. usually when they give a range, like 1.5-2, its better to make it the bigger size. companies know small boxes are in, so they say a smaller number than ideal to push there product.

what do you mean its better to make it the bigger size? what if you need to save room? usually people make it bigger because they have room to spare, and it also gives the subwoofer more room to resonate, if the box is too big it won't sound good, if its too small it won't sound good, it is up to the person, not just "the bigger box is better"

Well im thinking about building a 1 cu ft sealed box and then the basket will take up enough space to bring it to what the sub is made for and which ill probably do this weekend

if the company lists 1.5-2.0 it will sound better/louder in the 2.0. i didnt' say throw it in a 3.0. if you cant make it at least 1.7 (1.5+ sub displacement)look for a different sub, i believe the one he listed said for 1.5-2.0. you should also figure in port displacement

yes the bigger box is better for sq/spl. smaller is better for taking up less space, thats it...they only list smaller sizes because they know that thats whats in. it'll still work just fine, just not as well, and im not making this up, its strait from a few of the subwoofer designers ive talked to. you adjust the port for listening preference.

you will get quit a bit more from the ported box, but your welcome to try a small sealed box, ive seen it before, and ive fixed it before. most loudpeakers are designed for ported boxes

which sub are you going with? 1st one or 2nd?

the first you could do a 1.3cu ft box, ported, and its not much bigger than your planned 1.0. second, id do 1.5 cu ft, still not a whole lot bigger. you already going with a smaller 10" sub, your not going to get a lot of output, use the box to get the most you can from it.

if you do decide to go ported, find out what size port, and how deep. make sure the ports on the same side as the driver. if the port was to be 8" deep, the box must be at least 12", if it was to be 6", at least 9" deep (1.5 the port length) a little more space is always better.

ports can be sensitive, longer ports tune it lower btw.

Im going with the ID10 V.3 i cant go any bigger because of limited space in the back of my cab (Trucks are musily challenged)

Trucks are muscially challenged my A** http://impressivexpressions.com/Members/Scotts/REgoodies/videos/

Mike, you are not completely correct about your larger box better theory. Some subwoofers just perform better in smaller boxes. They are made for it. For example the Elmental subs. A larger box adds a lot more to the low end, but it doesn't really effect the subs high end performance.

Haibane see i cant do that to my bed i use it for loading my quad and hauling stuff so unless you convert you bed to a gaint sub box trucks are musicly challenged since theres no real good place to mount amps and subs

yeah, some subs are better for smaller boxes, but in my experience, when a manufacture recomend a range, the bigger in that range is usually better. if all else fails, email the company. ive done this for port tunning. told them the box demensions, and what size port/vent gives what hz. sometimes the companies dont give that info up so easy (just being lazy)

well certain companies need smaller boxes, usually for quality, but like for alpine, the customer service rep told me it just won't sound good... but for kicker the bigger the box is.. usually its better ya know? depends on the sub mostly

hey if any one can read this i have a question about building a good size box to house to l7 kicker 12 in square subs. 1500 watt max. i want to build a ported box for them but im not sure on how big to make it. i need the demensions. if you can help please email me at x20dollarsagramx@comcast.com

thanks,

Brian

not more than $200
