What does a bigger subwoofer box do vs a smaller box?
[Question]
I want to fit 2 15" P3's in the back of my car. I will be building a custom shaped box. but it will only be about 4.8 cubic feet, rather than the recommended 5.2 cubic feet...If I still tune the port to the same frequency, how will this effect the sound...thanks

it will not give the subs enough air to move to make the subs work to there potential. plus it can mess up ur subs. also it could blow the box apart clip our amp and do other things to cost you alot of money

bigger box deeper bass smaller box not as deep. and what the other guy said too. it can break

Richard D. @ 2009-06-25 10:46:51

It won't be as deep. Make sure you wood glue or liquid nail the inside of the box to prevent it from blowing up.

With only 0.4 cubic foot difference (0.2 cubic foot per sub) you will not notice much of a difference at all. The difference in sound would likely be unnoticeable or barely noticeable.



You need to make sure you tune the enclosure correctly to compensate for the smaller enclosure. The port length is related to the internal volume so if you have a smaller enclosure you need to make the port longer to keep the same tuning frequency.



What you could do, if you want to get around 5.2 cubic foot, is to add polyfill to the enclosure. You would need to cover the ports so it doesn't come out but other then that you would easily make up for the difference in volume.



Good Luck!!!

yea i think it would be fine aslong as you still tune the port.

I want subs, an amp, and a box to improve my car audio system. What should I get?
[Question]
I am driving a 2004 Dodge Ram 1500 that is four door. I want to know what kind of sub & amp combo would be the best for me. Also, I want to know what kind of box I need to get. Specific websites and brand names would be greatly appreciated. Thanks a lot!

i would go with two or one 12s pioneer, kenwood, JVC all of them are good and try to get a kenwood amp around about 500 watts it'll power those 12s perfect

Delphia55 @ 2009-06-25 11:41:49

since you have a truck I would go with shallow subs.

JL W5 would do good with a 1000/1v2 slash

JL is the best of quality.

Jamaal @ 2009-06-25 11:49:54

I also drive a Dodge Ram mine is a 2 door though

Memphis PR Series Subs- Cheap, Reliable, 3 Year Warranty



You will need the box to go under the back seat



Amp depends on whether it will power just the sub(s) or everything

demsoxsboyz @ 2009-06-25 11:50:18

I would recommend getting twin Memphis M-Class 10" Subs. The place you buy them at (if not a website) will probably be able to build you two boxes for around $100. A Memphis PR-Class 1000W Amp would be a good choice, as it could easily power both the subs and any stock speaker system, and it's a 5-channel (I'm pretty sure. Maybe a 4-channel.).

If you have the money to spend this would be a good amp.

Alpine PDX 1.1000

or

Alpine MRP-M1000

Either way look for a mono amp that has 1000 watts rms at 2ohms.

A very informative website, kindly stay a minute in website and check

JADE @ 2009-06-25 10:14:18

get a 2000 w Amp or stronger. or go with two 1000w amps and wire them together the amps usually have a low pass and a bass boost just set the setting right and it will blow out your windows lol jk

Richard D. @ 2009-06-25 10:14:39

if the rms of your subs are 100 rms and you want to hook both subs to one amp the you need to get about a 250 RMS amp when you get an amp dont look at the max wattage look for the rms thats really what the amp pushes a real 250 watt amp will cost you up around $180 or less.

Subwoofer + Amplifier?
[Question]
Would this be a good setup? I don't know much about car audio but I'm looking to purchase my first sub and amp - fairly cheaply.



Amp

Sub

http://www.sonicelectronix.com/item_11841_Alpine+SWE-1243.html







I want to make sure that the amp will put out enough power for it (I think it will - 220 RMS for a sub that's 250 RMS). How would they perform in general? I don't want to buy them and then be like "ah fuck...."



Also, what exactly does ohms mean? I know that you have to match them up but Idk what it means really.

Caliban @ 2009-06-25 09:57:16

if your lookin for a lil sumthang to just feel the bass not to rattle your trunk..i would go with kicker comps...you should get a 4ohm cuz you could basicaly wire it to any amp..usually the rms doubles..sub being 250 rms would be 500 watts max..

stockton209er @ 2009-06-25 10:05:50

It wouldn't be too bad of a setup, but your sub can hit 750 watts at peak power. I would get at least a 600 watt amp monoblock amp, alpine does make good amps I had one and was ver satisfied with it.

Also, I just found a website today that could save you money www.dealercostcaraudio.com they are cheap but still have the same stuff as all other people do.



Hope this helped you

pufhead2001 @ 2009-06-25 10:08:41

First of all DO NOT ORDER FROM DEALERCOSTCARAUDIO.COM THEY HAVE VERY POOR SERVICE AND YOU WILL GET A HEADACHE FROM THEM. It took SEVERAL emails and TWO months of waiting to receive my friend's 12W6v2. DO NOT ORDER FROM THEM WHATEVER YOU DO. Onlinecarstereo.com all the way if you want to order on the internet, they accept paypal and service is very well worth it.



Now back to what I was going to say. I remember when I was like you, looking for something cheap and match the sub with the amp. In all honesty don't go TOO cheap. If you do then you will regret it because you wasted all that time putting it in for nothing. You will want to to turn sub up and you will end up blowing a voice coil. For me to be telling you this, you are lucky because I didn't have any help with buying things when I first started off three years ago. Since you don't want to spend a lot of money I will give you a cheap solution but NOT that cheap. You won't regret it either.

Amp - http://www.onlinecarstereo.com/CarAudio/ProductDetail.aspx?ProductID=19580

Sub - http://www.onlinecarstereo.com/CarAudio/ProductDetail.aspx?ProductID=14956

---make sure it's the duel voice coil four ohm and not two ohm---

Total - $434

Reason why I chose that amp for is because Hifonics is very very dependable. I actually have this same amp at one ohm on a SS T5 and it's great. Reason I chose this sub for you is because Alpine type R's are cheap and very very hard to blow. They are not the best at sound quality but for your first system you just want it to work and not blow. I am not that big of a fan of Alpine but since you don't want to spend a lot, they are probably the best choice.

With this system your amp will be putting out 900W so don't put the bass boost all the way up although you could because the sub is strong. Safe side keep it 3/4 up. When you wire the sub, wire it in PARALLEL so the amp puts 2 ohm not 8. http://www.the12volt.com/caraudio/woofer_configurations.asp?Q=1&I=42

If you want to spend more later, JL, FI, or RE.

Trust me, this is the best bang for the buck and you won't be in the position where you blow a voice coil in the next year. You will definitely NOT regret it.
