OEM 8" SubWoofer Mod

Info: This is a quick DIY for fixing the problem with the stock sub...since the factory wired it up out of phase (backwards). This mod gives u better sound and better bass.

Total Time: 5-15 mins...but it really depends on how long it takes you to remove the wires and swap them...

Warning: Your bass will slap the crap outta your ear drums...proceed at your own risk.

Technical Explanation: by 03silvergt

Quote:
From the factory, the way the sub is wired... when the bass hits, the speaker(sub) actually moves towards the inside of the box. This causes the bass to seem as it is "pulling" away from your ears as opposed to the other speakers which are moving outwards and "pushing" the sound towards your ear. As long as all speakers are moving in the same direction, it will sound ok.

Note: (this mod did not work on one tib made in April 2003, we're still trying to figure out why)

Quote: ...I printed out the diy for rewiring my stock sub on tuesday morning and rewired my sub. Cruised around Tuesday with the astonishingly different bass that was being produced from my stock sub. Tuesday night at 3 a.m. someone busted the drivers side window on my tiburon and popped the latch for my trunk looking for an amp and subs, however the car alarm stopped them before they could get a look inside the trunk to actually see if there was anything back there... So in conclusion, if this doesn't change ur mind about the difference you will here if you rewire ur stock sub, then i don't know what will........

Required Tools:

- socket wrench
- very small flat head screwdriver (1.2 mm bit)
<like the one from an eye glass kit>

Procedure:

Image


* There are 4 bolts that need to be removed...start by removing the top 2 bolts. One is located on the strut tower cover and one is located just behind the tailight.

Image


* Carefully lift the trunk cover and remove the bottom 2 bolts.

Image


* Once all bolts are removed, fold-down your rear seats, then gently lift the trunk cover just enough to remove the sub...if u do it too rough, u can force the trunk cover to snap...

Image


* Once u have the sub out, just disconnect the connector by pressing the release mechanism...

Image


Next, remove the l_l_l shaped thingy from one side of the connector using the screwdriver.

Image


* Then use a flat head screwdriver to get inside the clip between the metal wire connector and the white plastic tab. Then lift the tab and have a friend tug on the wire. Then pull out the right set wires (1 black & 1 green) and swap them. Next, pull out the left set wires and swap them as well. The sound should then fall into place and the bass should start kicking once u install everything back inside your Tiburon. (don't forget to put the "E" thingy back in)

More on How to Remove the Wires

Quote:
....Look into the hole in the lower right hand corner where the metal clip is located. You should see a little plastic tab holding the metal plug in. If u pull on the cord u should observe plastic tab acting upon the metal plug....

- paraphrased from SuperWhiteTib's text

* Use a 1.2-1.3 mm bit screw driver or other sharp pointy metal object... Place this tool in the opening right under the metal plug.

* Once u place the tiny screw driver about half way into that opening, lift or push in the small white plastic tab that sticks out in there and presses up on the metal plug and prevents it from leaving the connector.

* As soon as the tab is lifted or "pushed in", have a friend try and slowly pull that particular wire out.

Re: OEM 8" SubWoofer Modification DIY - by sick shift

I thought both rear channels were backwards. If that is the case, then the 6x9's are wired out of phase too. It would be easier to remove the dash, remove radio, switch the 4 wires in the actual harness coming off the deck and then put everything back together. This would put all the speakers in phase, instead of the 6x9's fighting the bass still.

Im a newbie to this forum but have you tried this? is it easier just to switch the wires at the radio? Or is just the sub wiring reversed and not the whole rear channel? Thanks for your help!
:wtf:

Re: OEM 8" SubWoofer Modification DIY - by sick shift

hahahahahaha this is an awesome post! I'm at school and I'm surfing this site and I read about it and I wanna go home, skip all three of the classes (total of 7 hours of class) I have today and just go rewire my sub and sit in my car and listen...

I'm pretty retarded so I think this might be hard for me...hehehehehe :*

Thanks for the post!

Re: OEM 8" SubWoofer Modification DIY - by sick shift

hahahaha i rewired the sub...took me about 15 minutes cuz i couldnt find the freakin plastic thingies inside the connector...also took me a couple to realize where the |_|_| shaped thingy was...but all in all it is done...

sounds a little better...i cant say it blew me away, but it sounds better...i think people blew it out of proportion when they listened cuz maybe it was psychological...they knew it would accentuate the bass more so they were specifically listening for it...

anyways i am a happy man even though the difference isnt as great as everyone said it would be... :biggrin:

i did it twice, took me and 50 mins, pulling the wires were a biatch

you guys hyped it up so much that when i heard it, i thought it wasn't working sucked to much it had to be broken the first time. nope that's just the way it sounds, a little better i guess hardly noticeable. time to upgrade

anyone know the dimensions of the sub and the amp?

Re: OEM 8" SubWoofer Modification DIY - by sick shift

just did it myself - bass is noticeably more punchy.

one suggestion as far as taking out the wires, maybe this will help guide other people who run into problems.

if you are looking at the end of the white plug with the clip facing the bottom, you want to put the screwdriver (or whatever you use) on the top of the metal clip and then angle down while pulling on the wire. i'm not advoacting forcing anything, but it it does take a good tug to pull it out. did for me at least.

also, i couldn't find anything suitable so i ended up using a stick pin (like a thumb tack but with a handle) and it worked perfectly.

Re: OEM 8" SubWoofer Modification DIY - by sick shift

I just did this mod tonight and I have to say I love it! There's noticable thump in the car and it sounds much more expensive. Thanks for the DIY post. It took me about twenty minutes tops. It just took a while to get the bolts off because I didn't have a socket wrench. It still turned out well and it was worth it. Thanks again. I love it when the car thumps.....

Re: OEM 8" SubWoofer Modification DIY - by sick shift

well...this is interesting...cuz i actually used a flathead screwdriver...

looked into the end of the connector and saw the plastic piece...i wedged my screwdriver (it fit perfectly) between the metal wire part and the plastic clamp and used the driver like a lever to lift the plastic thing...after i did that once the wire just slid out...NO TUGGING AT ALL

as i was using the screwdriver as a lever it naturally pushed the metal piece out...maybe cuz the screwdriver has that little slant on it...

my mom won this awesome tool set as a door prize and everything is in that set so i had the screwdriver

Re: OEM 8" SubWoofer Modification DIY - by sick shift

I went out and did this mod today with this post printed in hand and got it done (took me a little longer then I would like to admit) I can't really tell by how much better it sounds - but it does sound better :p

Anyway the hardest part for me was getting the wires out to swap them - my advice: you have to push pretty hard the plastic bit lies on top of the wire to keep it from moving so you have to wedge your screwdriver (i used a 1.4 mm from one of those precision screwdriver sets) in between the plastic bit and the metal end of the wire pretty hard and lift - it wont be hard to lift it up but it is kinda tricky getting it in there.

All-in-all a mod that is easy to do (first thing I've done to the tib that actually involved a little thinking) and I think the end result is depending on your car.

I have a 2004 GT-V6 and I got a little improvement - your car might get you a lot more.

Re: OEM 8" SubWoofer Modification DIY - by sick shift

I used a tool set that I got for taking a celica GTS for a third test drive. In fact it was the same day I bought my Tib. It was a noticable diffierence but I don't think the warning was necessary. :m_thumrig

Re: OEM 8" SubWoofer Modification DIY - by sick shift

Thanks for the INFO! Just finished working on mine. I immediately noticed the difference, since I had the 'Evenescence' CD in the player. Play the song 'Bring Me To Life', it has some really LOW BASS at the beginning of the song......

Re: OEM 8" SubWoofer Modification DIY - by sick shift

I just did this to my tiburon and it took me about 30 minutes knowing nothing about speakers or anything. Definatly improved the bass sound in my car. I had to tighten my license plate afterwards because it was starting to rattle from the extra bass. :)
