so which subs should i go with for this box?

i also would like to add i have a memphis class d mono 500 watt amp i want it to bump any help would be appreciated

[gmalero2000]

Alos i have a shop up here that sells memphis PR subs that are 100 a piece and i can get 4 ofem and build a sealed box should i go that route?

[heineck]

talk to ryan from ohio, hes a god at this shit. and he usaully gets good deals on good equipment

[Cashdollar2009]

Ehh.. I don't like that box a whole lot. Go with a traditional slot port. And 2.48 cubes? Is that before or after port displacement? What is the port area? 5/8 mdf??? If you want to go with a prefab, you need to find someone who knows what they are doing.

Now to your speaker options... When the speakers are given with numbers, that would be their "recommended" box size. If they say 2.0 cubes, then through factory testing, they believe that the speaker typically performs optimally in that size enclosure. Some speakers sound better ported, some sound better sealed.

With the subwoofer options you have given, it's hard to decide between them, since none of them are that high of quality, you really won't notice much of a difference. Ryan may step in and throw you a few options. I've finally been able to hear a few setups with American Bass subs, and I was rather impressed. A few other routes you may look at that won't run you hardly more if any would be DC Audio level 2 or 3's http://www.dcsoundlab.com/woofers.html or even the Fi ssd series. https://ssl.perfora.net/www.ficaraudio.com/sess/utn154bfa73b865693/shopdata/0050_Speakers/0040_SSD/product_overview.shopscript

Could you link your amplifier on here please? A lot of times "500 watts" doesn't mean 500 watts rms. Then again typically memphis had their amplifiers name to their power ratings...

[gmalero2000]

heres my amp

16PR1-500 - Memphis Power Reference 500Watt Mono Amplifier

[gmalero2000]

im probably going to go with the Fi series. but now i gotta buy another amp lol

[gmalero2000]

why are the lowest grade subs rated at 800 watts rms tho? are they that rediculous?

[gmalero2000]

heres my next question should i go with 2 12s 2 15s or 1 18?

[gmalero2000]

with my amp ill probably just get 4 memphis Pr 12s and build a box and buy another amp

[Gr1m]

holy multiple posts batman

[Ryan from Ohio]

That box is atrocious... Someone barfed on it.

I may have some sub options, I will get back with ya tonight.

Given that amp theres not many options though.

I know I can do Hifonics HiFi 12's for a decent price. They would work out right for you. Around $100 per pair. Maybe less/more but a rough estimate. I dont have pricing in front of me.

[gmalero2000]

do you know the rms on them?

[Ryan from Ohio]

300 WRMS DVC 4 Ohms.

You can wire them to 1 Ohm, get the full 500 WRMS from your amp. You wont notice the difference between 500 WRMS vs 600 WRMS...

They would probably work in that box you posted also.

[gmalero2000]

hey ryan i was gunna try n get these would these work ok and be wired to 1 ohm? and i was gonna get another amp


http://www.dealercostcaraudio.com/kfc-w3011.aspx

because i plan to make a full trunk box for 4 12s and add 2 more 12s later on down the road

The kenwood amp i want will only run to 2 ohms but my memphis will run to 1 ohm

so i will buy 1 2 channle amp try n sell the memphis and buy another

[gmalero2000]

or are hifonics better than kenwoods? and can SVC subs be wired to 1 ohm?

[Ryan from Ohio]

It would take 4 of those 12's to get to 1 Ohm.

Im not sure what your goal is. The subs selected so far are low end, and now you are after 4-6 subs.

You would be best suited to figure out what you want. Set a budget and go from there. Otherwise your going to end up with many low end subs where you could get 1-2 good subs and be done with it.

$44 is a cheap sub. I think I can do the HiFis for $40 each.

I would highly suggest getting 1-2 good subs vs 6 crap subs. You will thank me later! More crappy subs isnt better than 1-2 good subs. Not even close.

[Cashdollar2009]

Listen to this.

Now honestly, get a budget on what you would be willing to spend on two subwoofers. There is more to bass and sound quality than the quantity of drivers. (subwoofers) Get a budget on speakers and an amplifier and a few of us on here could give you a few legitimate options. Do not go the four or even 6 driver route. You'll be wasting your money in place that you do not need to.

[gmalero2000]

ok well what should i go for i have 189$ for 2 subs what do you suggest here are my options(i have a memphis pr 500 rms mono block amp already)

there are my options please please please help me out narrow them down to the top 3 best and ill pick from there or pick the best

[Afugy]

You'll never get 4 12"s into the trunk of an Alero, the trunk at best is 13 cubes, its best to at most only use half of the air space in a trunk of best SPL. Unless you have the box going into the cabin of the car it's not going to happen. By the way that box is only 2.48 TOTAL, thats only 1.2 for each sub. The box in my car takes up 8 cubes so I had to seal it off from the trunk, with somewhere around 2000rms I'm doing 143.1 db, thats loud. I could build you a good box for 2 12"s ported for 100$ to 120$ plus shipping that will be better then any prefab box, just depends on how strong you want the box. What state do you live in?

[Ryan from Ohio]

Out of everything listed I would advise the HiFi subs.

The Kenwood subs like their speakers suck. I wouldnt sped $79 for kenwood anything- maybe a head unit. Forget the rest- all junk.

It will utilize the power you have well and it will do it cheaply.

I can match $35 a sub. That pretty low dollar though- only a few bucks over wholesale. Only reason I can do this is because I have another order to do... So if you want them, we need to talk then.

[gmalero2000]

Ryan i also have another question. are the hifi subs good? will they hit respectivlely? are they better in a ported or sealed box ,would the box i posted before work or should i have somebody build me one?

[gmalero2000]

heres another option

http://www.dealercostcaraudio.com/memphis15-pr12d4.aspx

rated exactly for my amp

[Ryan from Ohio]

With the HiFi subs you need 1.75 cubes per sub, tuned to 40 Hz. Or you can go the simple route and the one I would advise for a newbie, and run a sealed box. When you learn and know enough about Car Audio then make the switch to ported.

I think this will be your best bet.

Depending on your location I could build a box for the subs and ship the box with the subs installed.

[gmalero2000]

i live in missouri how much would it cost? i only have 180 bucks to spend

[cherrington17]

save money, get better equip. You have no idea how many times i've upgraded my stuff, because i'm able to save more and redo it.

..if i did it right... i would have saved about $1k in the long run. (which could have gone to totally sound dampen my car with GOOD stuff)

[gmalero2000]

i think im gunna go back to my old setup of memphis power reference 12s i git 131 dbs in a sealed box with 2 PRS they hit very well

[Ryan from Ohio]

The big thing here is your amp... 500 WRMS x 1 @ 1 Ohm is hard to find subs that will work.

[widbyj]

Wouldn't two 2ohm speakers wired in parallel give the requested 1ohm effective? So then you would be looking for 250 WRMS speakers?

just thinkin out loud...

[Ryan from Ohio]

Sure, but how many 2 Ohm subs are there?

Its even hard to find many decent DVC 4 Ohm subs in his power range.

[gmalero2000]

memphis power reference 12s
DVC output
500w max
250W RMS

[Ryan from Ohio]

Well there you go then, get em.

[gmalero2000]

thanks for the help ryan the only problem is i dont know the cubes for these subs as they do not tell me

[Ryan from Ohio]

Contact a dealer

[gmalero2000]

okay ryan ive found out the cubes for 2 memphis subs the cubes is 3.70 is there even a box that will fit the trunk of an alero with 3.70 cubes?

[Ryan from Ohio]

Ive had more than that in the Alero.

You will just have to measure well to make sure the specific box you are going to buy will fit.

[gmalero2000]

will 36'' long fit?

[MattismodderX]

my box is 3.9 cubes for a single 12 and a stupid huge port. that brings it close to 5 cubes. fits in the trunk quite nicely

will 36'' long fit?

take some measuring tape and find out lol

[gmalero2000]

i cant my cars not with me atm

[Afugy]

okay ryan ive found out the cubes for 2 memphis subs the cubes is 3.70 is there even a box that will fit the trunk of an alero with 3.70 cubes?

3.7 would be so easy to fit, like I said my box is 34x16.5x26, that fills 8.6 cubes of trunk. Thats 3.7 for a sealed box, correct?

[gmalero2000]

they did not tell me all i know is the ported boxes that are mated for these 12's is 3.70 cubes they do not give the demensions as to what the width is of the box

[Cashdollar2009]

Buy this and call it a day. :/
