rated exactly for my amp

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.

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

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)

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

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

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...

Sure, but how many 2 Ohm subs are there?

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

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

Well there you go then, get em.

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

Contact a dealer

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?

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.

will 36'' long fit?

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


take some measuring tape and find out lol

i cant my cars not with me atm

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?

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
