I always run everything right at the limit, even if it was in a proper box and retarded loud it'd be set up to just be under the clipping level at the max volume I listen at

I've got a friend doing me up a nice dual 12" ported box that's going to be sealed to the passenger cabin (subs and ports firing forward, seats down).

He suggested I use my existing 1000/1 to run both of the RE Sex 12D2's. He said in the ported box 1000 watts to each would blow them up in a hurry, lol.

I'll cancel the order for the second 1000/1 I guess

uh ya if u dont have self control then u match the subs up to the amp... reality with car audio is amp and sub power doesnt HAVE to be matched but u have to know what ur doing really well if they aren't.

I had my T40001bd on a 450w DD 1500 8" and had my 2 1200w RE's on a 100w fosgate amp. both worked out just fine and ran for 2+ weeks each (i think i had the 100w fosgate in there for a grip thou bc i was lazy not wanting to work on my car)

Can't wait to see how this turns out. Im looking to ditch my 12" JLW3 with ported box to save space for gear and stuff while still having some base for rock music.

With that Polk Audio MM1040 in the stock box I think it's just gonna rock! Should be nice and tight and punchy with any amp 300rms or over!

Woot! Car is all measured, two 12's will fit the way I want!

Rough design of box is done too! Tuned to 32hz



Sweeeet.

I ordered the Polk MM1040 with the single 4 ohm voice coil. They also make it in 2 and 4 ohm DVC. I will post pictures and give it a review once I have it all setup. Probably wont be until the later part of March though.

ur getting a new amp too thou right?

toysareforboys

Yep! He's getting or has already got the Alpine MRX-M50. It'll do 300 watts RMS at 4 ohms to the new sub and has speaker level inputs. Should be a HUGE upgrade from stock

Pics and vids when you're done. I've got a few friends who want to do the same upgrade (same sub and amp) and they are waiting for you to try it first! lol. No rush, we won't be getting nice weather here until at least april

thank you jamie, i'm probably gonna go with that sub! and that one shouldn't need any 'porting' of the stock box i take it?

very good informative thread here, and fyi, i too am just looking for a little moar bass, nothing crazy, thats what my monte carlo was for,

in my philosophy, jj, i think its best to have an amp that underperforms the subwoofer capabilities. so like a 300w rms amp for a 350rms sub. that way you dont blow the sub..

EmperorJJ1

true but to be honest its much easier to blow a sub with a smaller amp then a bigger one... turning it down if its too much power is simple. turning it up when ur power is maxed just makes the signal dirty increasing ur chance of blowing the sub

toysareforboys

Almost all subs require you to trim the inside of the mounting hole a bit, but give it a try when you get it. Make sure it sits nice and flat, if not make the hole a little bigger. If you're mounting the sub inverted make sure you trim the opening a good 1/4" all the way around, so the speaker surround doesn't rub on the lip of the opening.

Good luck, should be awesome

sweet! i DID get a little thrown off by the 200-300 dollar price though, i was hoping for a better option more in the 150 range... just more $$$ i gotta throw into this thing now..

toysareforboys

What was $200 to $300? I posted a link to the polk for $86 with free shipping??

this all seems like a lot of work for what you would get out of it.

i would just build a small box, or if space was really that big of an issue, fiberglass a sealed enclosure in the stock location.

im sure with a "better" sub and more power that stock box would flex like crazy

whoops nevermind saw the link now. yea on ebay they were going for like 200 bucks or so

reefone

is that all u did to mod ur stock box? did u add any poly or reinforce it at all? its been a long time since ive been into car audio and am not current with brands. r the re audio subs any good? ive got a amp laying around that i could use for this but im afraid of this

re subs arent what they used to be but still good

toysareforboys

I sealed around the two halves of the box with Permatex Black gasket maker, as well as sealed the bolt hole in the rear of the box (bolts to the stock magnet in the stock sub) as well as sealed the hole where the factory wires ran into the box (cause I mounted it inverted).

The box shakes and flexes quite a bit with the RE on 1000w RMS, but was OK on 500 watts. I love the RE sub! Great excursion for nice deep base Takes a beating and keeps on ticking! For around $150 I don't think it can be beat

Because the surround is so fat on the RE i had to trim about 1/4" off all around the opening (then filed it smooth). Sub just dropped right in, and all the screw holes in the RE are identical to the stock sub, so she just bolted right up. I also used Permatex Blue gasket maker around all the screw holes and around the outside of the sub frame to make sure it was sealed perfectly to the box.

I hope so. I have a Rockford Fosgate Prime R500 that is 320 watts rms at 4 ohms on my ported box with my Jw3 right now. I don't need it to be really loud or anything, just looking to ditch the huge ported box while gaining my room back and maintaining some bass. Hope there isn't much custom fitting to this job.

i used to have an r500-1, but got a new setup. it was a great amp for the price, but got REALLY hot

reefone

thanks for the info guys. i think im going to give this a try.

just bought it super excited, thank you to jamie and everyone else for doing all this in depth research and figuring what kind of subs work best in our boxes! could NOT have done that alone

Install yet?

I'm in the process... Here is the thread https://www.cobaltss.net/forums/elec...mm1040-272729/ I am playing the waiting game on a 3/4 inch MDF ring. The Sub sticks out 1/2 inch. A little more work than originally planned but It should be worth it.
