Ok, I don't own a vette, but since i lurk alot in the c5 section and in OT i figured id post this question here since it has to do with sub selection and I figure that a majority of the people checking this section of the forum out have much more experiance with building quality systems compared to those over on the boards that are for my dd.

Here is my current setup

Eclipse CD3434 Head unit (50W x 4 channels of power amplification with MOSFET)
4x Pioneer TS-A6871R (3-way 6"x8" speakers fequency response: 30-28,000 Hz power range: 2-50 watts RMS (240 watts peak power))

Now while this provides me with some good sound i still wish to add a subwoofer. While of course keeping a tight budget.

As per my music tastes: 60% of the time its Rock 25% its hiphop and rap 15% of the time its Techno/dance music.

So i am basicaly looking for something that will give me an extra push. As well as not taking up a crap load of space in the car since its my dd and i use it to cart all sorts of things. For this i've found this one guys setup to be superb.




What concerns me is that i am unsure what size of the sub this is and if the guy truly has enough cubic feet to get a decent sound.

The space is 15x17x7inches which gives me just over 1 foot of cubic space if i were to do a sealed box.

So far i've done a little bit of looking for a cheap sub and i've come up with two i like. One is a 10 inch and the other is a 12 inch sub

The first is a MTX Thunder 4500 T4510-04
stats:
# ower range: 50-225 watts RMS
# peak power handling: 450 watts
# frequency response: 35-150 Hz
# sensitivity: 87.6 dB
# top-mount depth: 4-5/8"
# sealed box volume: 0.6-1.0 cubic feet

My question is that if i went with a .6 cubic feet box will that hinder the preformance of the sub vs of going with a 1.0 cuib feet box?

The second is a JVC CS-GD4300 12" (comes with an amp for 120 bucks from crutchfield)
stats:
frequency response: 30-2000 Hz
power range: 50-250 watts RMS (750 watts peak power)
sensitivity: 85 dB
top-mount depth: 5-3/4"
sealed box volume: 1.50 cubic feet

This is obviously larger in terms of cubic feet but, would it be better to go a bit larger and make a larger box of 15x17x8.5 inches?

so what would u guys do

 

Look at the Elemental Designs subs - awesome quality, they kick a$$ at a low price.

Also, look at Bazooka powered tubes. They take a bit of space, yes, but they sound good in a small car.

Can't really help you with non-C5 stuff, but I can tell you that head units vastly exaggerate their power output. Your "50w x 4" is probably 19wrms into 4 ohms x 4 in reality. Caveat!

Good luck

X2 on an elemental desgins 12" for the money you cant go wrong

 

thx EG u rock

I'll have to read more about this stuff

it seems like the SQ10 Subwoofer only needs 0.5cF for a sealed box which is awsome.

I am glad i asked here, no one over on the other forum has heard of em.

 

they are a good company check out there forum at icixsound.com some great guys, also call em up someone always answers the phone its a smaller business good people, 50% the time the owner answers

 

Another vote for eD brand. I think you can work with their 13Kv.2 in your available space and definitely could fit their 11Kv.2 (recommended air space is 0.50 cu ft). I don't know that you really need their slim line series unless mounting depth is a problem. The mounted depth of the 11Kv.2 is only 5".

If you want even more output, you could step to their Ov.2 series which will handle more power. With your music selection of rock, rap, and hiphop....I would lean towards a 12" sub (the 13Kv.2 or 13Ov.2 from eD). That 12 will still be tight sounding if you stick to their recommended airspace (0.7-1.0 cu ft, 5.75" mounting depth) and get low for the rap/hip hop music. But a 10" sub will work for you too.

 

for some other options, check out the image dynamics subs. i had one and loved it

 

Just a quick question and it may seem rather stupid but, can some one explain what Single 2 or Single 4 Voice Coils would be?

Some subs i have an option in getting a single 2 or a single 4 voice coil but i ahve no idea what it means.

 

Hi,
The dual voic coil sub give you more wiring options but that doesnt mean those are the "right" subs for you. What you want to do is match the sub to the amp. Since you are using one sub here are some of your options.
If you plan on bridging a two channel amp I recommend a single 4 ohm voice coil or a dual 8 ohm coils. If you plan on using a single channel amp (which I recommend in your case) get a dual 4 ohm voice coil sub (wire coils in parallel for a 2 ohm load)
In the future, save $ for a 4-channel amp
Best wishes

 

KnewBlew pretty much hit that one on the head. Sometimes you may see the terms SVC (single voice coil) or DVC (dual voice coil). The 2 or 4 is referring to the impedance (ohm) rating of the voice coils.

In my truck, I have two DVC subs that are 2 ohm voice coils. I wired each sub in series creating a 4 ohm load per sub. I then run them parallel to the amp creating a 2 ohm load at the amp. My amp is a mono block amp.

It can take a little bit to understand impedance ratings, but just keep asking here. We'll help you out

 

I was planning on getting a single mono channel amp (as i plan to only run the sub off of the amp in this car). I do have this old kenwood i got for free back in the late 90s that can put out 150W max on 1 channel and also has the ablity to do 2x 50W i think i don't belive it will be enough to push the sub.

Most of them i am looking at thanks to EG need around 400 to 500Wrms.

I found a few cheap $100 mono channel amps. Visonik V108XT and Profile HA700M

I would just like to keep the amp under $130 bucks i figure if i can get away with a sub and amp for 250 its a good deal.

 

profile is a great bang for the buck amp ive used a number of em and not one has yet to die. check out profilecaraudio.com they have referbs on there for dirt cheap i use em in a lot of budget systems
