Hi to all experts here. I have some queries here and i hope you all can give me some advice. I'm currently driving a civic eg hatchback and my current set up is
HU - Pioneer p7750mp
Speakers - CDT HD61
Amp - Soundsream Reference 705s
Subs - 2 x Sony Xplod 10'
I'm thinking of dumping my 2 sony subs in exchange to a good 12' sub. I'm a R&B n Hip-hop guy so i ask the guy who did my last setup to give me some advice and he reconmend me to get the Soundstream 12' subs. and change my HU to support it.
Now i wanna ask
1. is it advicible for me to change my 2 x 10' to a 12' ?
2. is there any other reconmendation from u experts here on which subs i should get?
3. is there any different if due to not enough space i place my sub inverted? or make the sub box smaller than reconmended space required?
4. is my current HU really not able to support my upgrade as this HU is still very new.
I would like to thank you all in advance for reading my post. Hope to hear from you all experts here soon. Take care n Stay happy :)

i don't know if i would consider my self an expert but i don't see changing your H/U as a good idea and do not make a box smaller than recommended you will not get full performance from the sub i think going from sony to soundstream is a good idea i would go with a 15" sub if you are going to go with a single sub also what soundstream sub was recommended ?

if you are going to do that go one step up to the van gogh you will get better SQ and the van gogh needs much less airspace

Your head unit has a subwoofer pre-out, so there is no reason to upgrade it unless you simply want to. WHoever told you it needed to be "changed to support" subs was not well infomrmed. ------------- Support the12volt.com

+1 on the Van Gogh over those you mentioned, also on leaving the HU alone. someone's just trying to sell you a new deck. The real question is what do you want to accomplsh? Any quality sub IMO will greatly improve on those Sony drivers, but why go to a 12" instead of 2-10's? Are you looking for more bass? smaller box? Do you want it to "boom" with the R&B? Just more volume? How important is sound quality vs volume? What kind of box are the sony's in now, and do you want to keep that box? Answer those ??'s and we can give you much better advice. -------------

Personally, if faced with a choice between a Pioneer head unit and say an Eclipse  , I would say do the Eclipse. To say that the Pioneer cannot support the new sub, well that is misleading. Whatever you do with the subs, it is all about the box. the box will make or break whatever sub you end up using. ------------- Top Secret, I can tell you but then my wife will kill me.

this is how my 2 x 10' is placed right now... i'm thinking of removing it and place 1 x 12' or 15' inside. there's a bigger space underneath it now as i won't be putting my spare tyre in. i'm going for SPL , details n loudness.... i know i can't get the best of both world but i hope can be somewhere there .. :)

So it sounds like you want something with more output and hopefully with good sound quality also. That right? Since you didn't mention it, I assume box size & architecture aren't very important. Given that, I'd say go with the 15" in a ported enclosure.

I've always found a pair of 12's being the *best* combination between volume and precision.
Hmm.. whoa your amp looks absolutely awesome.
Do actually have bi-amped CDT HD series speakers running off that thing? I'm *really* jealous.
It looks like your subwoofer channel is good for about 300 - 400watts at 1-2 ohms? I'm not sure if I'd mate a VanGogh to that... you'd be at barely half RMS.
I think the original recommendation of the XStream sub was probably the best pick, at least from the Soundstream line. Not sure what the deal with the embossed Tarantula though. I really can't deal with that at all.
Here's what I think.. if whoever did your system the first time was smart enough to pick an amp that cool, then mate it CDT HD stuff in that manner, clearly he knows what he's doing. Find out *why* he wanted you to swap your deck b/c I really can't explain that.. but just looking at your system componets I bet your high end sounds about as good as it can get.
Is this guy a sales guy at a store or just a friend of yours?
Here's the bottom line as I see it.. with a top end like yours I'd mate your amp to the sweetest sounding subwoofer I could get.. a long excursion 12 maybe. In a hatchback you certainly won't have any output problems. Why don't you post back with a budget and we'll kick it around a bit.
Honestly though.. with the superficial exception of that stupid spider, that original soundstream sub looks great... err.. looks like it would sound great. Inverted. Definately invert that sub.

A 15" ported box with a top end like his?
Please, please don't do that to your stereo. Please.

Going from 2-10's to a single 12" is going to amount to a lateral move in terms of bass output, if not even less output. If we're talking about a pair of 12's, that's different. So if output is the goal, the 15's the way to go. I'm not a big fan or ported/bandpass boxes, but that design seems most in line with the goal & the type of music you're listening to. It may not be what Sedate wants your system to be, but I think it fits what you want it to be. To answer your other question, the only real advantage to inverting the sub is that it adds volume to the box equal to the displacement of the sub - basically makes your box bigger. Plus there are some style aspects. But now you have a sub sticking out into your cargo area which can cause other issues. Better IMO to just make the box a bit bigger & keep the sub inside it. If you really want something trick & space is an issue, do a clamshell design in a box about half the size with 2 drivers. You'll only get the output equal to one sub in a proper box, but it's a neat design at the least.

hehe okay point taken.
Still, I betcha 1 Soundstream 12 will be louder and cleaner than 2 Sony*anything* subs. Seriously. That stuff is really crappy gear.
Anyway... like I said above, best combination that fits into the realm of realistic installs is usually 2x12's.. they'd be louder than a 15, if not quite as deep.
Anyway, with 200watts/sub available to ya, you won't starve. Maybe $300 - 400 at most.. 'course if you are in Singapore, I really have no idea what you could get at what price.. but.. stateside.. I'd recommend something along the lines of a pair of any of these:

Honestly, there are about a zillion different subs you can get that fall into the area you are looking at. Try finding stuff you like and then bounce it off us eh? ------------- "I'm finished!" - Daniel Plainview

sorry for my ignorance but may i ask what does it means when it says this sub allows free air usage?????

Means it doesn't need a box. You could mount it on the rear deck w/o an enclosure.

i would suggest a single 15" sub dual 2 ohm so you can run your sub channel @1 ohm and a vented box ------------- 1974 ford pinto 4 15" punch Z power punch bd 1001 pioneer DEH-6700

After reading so much advise from all experts here and some research i did myself, it seems like switching from 2 x 10' to a 12' won't be much of a different and i can forget about subs tat are free air usage as i'm driving a hatchback.
I'm now thinking of getting a 15' but i'm worried that my soundstream amp will not have enough power to fully power up a 15' as i see most 15' minium watt is 700wt and above. I do see some 15' which only needs 400wt to power it but will the SPL lose out?
ps: recently my sound system have this high pitch whenever i start my engine n it gets louder as i rev my trottle.... may i ask if anyone knows wat's the problem and how to solve it???

I don't think your amp will have any problem powering a 15" sub - those aren't minimum wattages you're likely reading. 15"+ subs are usually built to be ABLE to handle more power than 10's etc b/c that's typically how they're used, but in terms or power requirements there's not much difference. Look at the specs & check the number for "sensitivity." Compare to what you're using now for a reference. This is the amount of sound output with 1 watt of power measured from 1m away. As long as you get something comparable or better you're in good shape. Expect numbers to be around 85-90db, the higher the better. A ported/bandpass box will be more sensitive at certain frequencies, meaning louder with same power than a sealed box, but less balanced, less controlled & more colored.
