Does the structure of the boot affect the sound of a sub?

[Go_Slow]

Just wondering wether anyone here knows about the structure of boots and there effect on sound waves from a sub.

I had my sub in my VR, for quite a while and you could hear it go off and the boot would rattle like hell.
Now its in the VY and you cant really hear it.

My mates sub in his VS goes off. Another has a VE Exec and I was listening to his and it sounded the same, another mate has a 200sx and the sub goes nuts.

I was speaking with a bloke at the audio shop and he said to run 2 12's in a commo instead of just 1 12, because they have poor bass response due to the structure/size of the boot. He right?



Though the difference is I have another AMP, pushing only 150RMS, (my first amp was one of ebay) , (my sub is a pioneer 800watt, 150RMS)


Is it just because the combination of sub and amp are weak? or Because of the boot, or other factors you guys might know.

With a sub thats only 150rms im suprised it ever performed that well

Its pointless comparing your sub to other subs in other cars. But smaller cars generally produce louder bass/db as its a smaller environment. The VY probably blocks noise outside the cabin a bit better than the VR also.

i dbe upgrading your amp and sub if you want it to be the same as your mates. probably only cost a couple hundred dollars depending if you want to save boot space. if you do i would go 1 quality 12" sub but if you dont mind not having boot space. 2 cheaper 12's will go harder but will take more power.

From my expierence and listening, I would have to say yes, the structure and size of the boot effects the sound of a sub wether it be Sedan, Wagon, Coupe.

Me and My cousin had the same identical set up in our cars, i had one in my VS sedan and he had a setup in his '95 Toyota Supra (mono-block running 2 x sealed 15's)

CLEARLY my cousins system shat all over mine, it sounded massive and the bass response was monsterous.

Different size cars will affect the volume of a sub. The same sub in a small car will sound louder than in a large car.

Since you're comparing a large sedan to a large sedan, the position of the sub in the boot, the type of sub and power to it, the type/size of box can all affect how different it will sound.

If using cheaper subs, which are usually quieter, then two 12's in a large sedan is preferred as it will give more output. If you have a single cheaper 12", some people are likely to turn it up too loud and damage the sub. So the guy in the store was right... IF you want big-ish bass cheaply, you'll want 2 subs.

I'd have to say your sub and amp combo is probably your problem... Get more power and either a better single sub or a couple of subs.

yeah you make sense, i brought the amp last week from jbhifi.
it was pioneer 3300T.. 150rms, little tight on cash though.
i went back yesterday and the guy was like, why did you buy that? I woulda told you to get this audio'something' one which pumps 300rms, and was saying that subs only want power and since your only amplifying a lower frequency of sound the brand of the amp doesnt really matter, only the size and amount of power going to the power hungry sub.

the sub will have to stay for a bit ive had it for ages, still got the reciept for the pioneer amp. you guys think i should change my pioneer 150rms to a 300rms lesser(audioline) known brand?
I'm leaning towards yes... But maybe someone here knows something I don't?

O when i brought the amp jb had 20% off, the 2ch audioline was 149, and the pioneer 179, but i got it for 125. would prob get the audioline one for something less than 125.
let me know what u guys think, ill be heading to jb 2moro night.

[1991_Vn2nV]

Ahh I wouldn't touch that other amp mate.

You get what you pay for.

[r_i_d_a_h]

lol..'audioline' is like strathfield's equivilent - boss

[Go_Slow]

lmao. looks like it a no go for the audioline...

ill keep the pioneer then, or maybe give a bit more for a better pioneer amp.
I want to do everything properly this time round with no cheapies. I just thought if it didnt matter for a sub so much then why not.
whole system is pioneer so might aswell keep it all the same.

Cheers 4 the input. The Box I got is just one of those standard ones you can get for a sub at jb. they ****? Also where do you guys mount your amp in your boot?(VY)
Under the parcel shelf? I was reading through the posts and its sayin that repetitive vibrations is no good for components inside subs, but no idea's given as to where abouts to put it. I was growing to screw it in upside down under the parcel shelf, then a post said, dont put the amp upside down because heat rises or somethin.

Ideally you would want to replace both the sub and amp, I doubt you'll get much better sound from the amp the JB guy recommended. On a budget this tight I'd look second hand. Look at entry level pioneer stuff or equivalent (pioneer 306c or 307c seem the popular choice), and maybe a jaycar amp (another popular choice for budget systems).

Jaycar do a 2x150 model that can be bridged to 500w rms for $249 rrp, which would run the above pioneer subs perfectly. There's plenty of them around as they are really popular.

Check out classifieds on this site, check out ebay, trading post or whatever.

[padrickz88]

dont go the audioline amp , its not that great....

i would suggest getting these 2 brands
-coustic (cheap and reliable)
-response (jaycar, same as above)

or, go look on Mobile Electronics Australia | Forums | Product Reviews | Custom Installations | Advice | Tips | Community and look in the for sale section for a cheap and reliable amp

Boys, Walked into JB today and said "mate, this amp you sold me, I cant here it. gimme something that'll make it rumble". (hehe on tight budget)

I got a Pioneer D7400M Class D Monoblock. pumps 200rms at 4 ohm and 400rms at 2 ohm. (paid 220) (im sure there are better, more expensive onees)

I hooked it up and the difference is massive

I step out to the front of the car and can hear it :-)

Its ok though, I'll upgrade the sub someday, after I wear it out with this amp. but for now. Its goin off for a 800watt cheapie.

You definately get what you pay 4.

Two Questions.
1. When I'm adjusting the gain how do I know where to stop when I"m pushing up my gain? (So the amp doesnt give too much to the sub)
2.cd player though.
(pioneer) When I press the eject button for a CD, the whole cd player turns off. Why? did i wire it wrong? (it holds memory) or is in its settings?

[Go_Slow]

Disregard my question about the gain, found a tute on the forums
cheers

still hoping for an answer about the cd player though.

[r_i_d_a_h]

ummms, i think that is normal for the head unit to do that, some H.U's usually go directly to the radio but mine just turns off. (DEHP5850)
