05 Limited JBL Synthesis Sub Swap

My sub began making odd crackling noises today and I believe it may be blown. It rattles very annoyingly when playing music, even when I manually turn the sub "off" via the HU. I never remember hearing it sound like this, so I'm assuming it may be blown.

What options do I have for replacing it? Rather than drop $300+ on a new toyota replacement, I'd prefer to get an aftermarket sub that would still fit in the same location (behind the panel) and sound good. Anyone have any suggestions or point me in the right direction for options?

Not looking to drop a ton of money on it, but want a good bang for my buck, if you will, while keeping the look OEM....

Thanks in advance!

Thanks for the links! I have been reading ARK's thread for a while as I put my list together.
You put alot of work into yours and it looks good!

Do you think I can chip off the plastic ribbing inside the sub box with only hand tools? I don't have any power tools with me right now and hope that doesn't prevent me from doing this upgrade....
 
Do you have a small torch? You could spend 10 bucks on a pocket torch and use it to heat up the plastic and cut it out with a utility knife.

I think you misread what I said. I haven't done my install or my thread yet. :nod:

Well depends on what sub you want, I know you can CHIP off the ribs with pliers but if you go the sub that me or 97 are doing/did (8W3) then you'll need a grinder of some sort to grind out past the ribs.

BTW, Dremels are cheap

or a single speed one for less

No torch for me! I spoke to ARK and he said with the sub I'm using (JL 8W1v2-4), I can get away with chipping at the plastic ribbing with a flathead and hammer or use pliers to pop the pieces out. Hopefully it won't be too bad.

Yesterday, I took out the panel to get access to the sub so I could at least disconnect it. The sound was horrible when music is playing even at low levels. It was a pain to rip it all out, so I'm leaving it like that until I do the swap.

Still debating whether I will use RCAs or speaker level inputs. I have a Pioneer AVIC-D3 HU in right now, but have never ripped the dash apart to get behind it, which is what I'll have to do in order to plug the RCAs in there.


Anyone have recommendations for an amp install kit? I was going to use a 4ga kit with everything included to cut down on cost. I found one for a good deal but then saw a review on amazon that was pretty bad so I figured I could pony up some extra $$ for a better quality wiring system. Here's what I'm deciding between right now:
Audiobahn AKIT4J Amp Installation Kits at Onlinecarstereo.com

Rockford Fosgate RFK4X Amp Installation Kits at Onlinecarstereo.com


Any input is appreciated!
 
Either one of those kits should be fine, but I would recommend piecing together your own kit using quality components. You will only use about half of what is in that kit by the time you are finished. Hit the local stereo shop and see if they can hook you up.
 
Hey Snow,
I'll chime in here real fast for a little info; I just did my install over the weekend...wow alot of work. I did all new everything (minus the SR tweets), removed all the stock components and ran all new wiring. First thing I'll say is that every write-up I used, looked at for tips, or scanned...was missing information or incomplete. Even peoples removing the panel that covers the sub/amp were missing a screw or clip or bolt. So first off be very patient. This will take time undoubtedly even for a pro the way we are doing this.

I'll have more information when I create my thread about my install. Feel free to ask anything though. I'm still working on adjustments for my amps. This new sound is just amazing.

I concur with the information provided by Ark about that sub fitting by just clipping out those ridges. I used the W3 and I got it to fit with alot of grinding/sanding/custom spacer. BUT! I was able to fit it behind the panel still and not effect the airflow.

RCA, RCA, RCA, RCA. Ripping the dash apart is very easy. I did it, oh lord how knows many times to test fit and sheer forgetting something to tear it apart again.

I actually bought ZERO gauge Memphis wire but ended up using the Rockford 4-gauge kit; the one you linked. In regards to the wiring kit, make sure you get extra either battery terminal connectors or different battery terminal adapter for that end of the power & ground cable. I had to customize my ground end for my speakers amp. Also if you're doing two amps then you'll obv need a distribution block and another power n ground cable. UNLESS, you have excess cable from battery to distro block and just cut/reuse excess. Which you should but better safe than sorry. I don't know your placement so can't say for sure.

Thanks for the info, BrightLight! I too, followed a writeup for removing the sub panel in the trunk and discovered a bolt that was not listed that I had failed to remove. Glad I discovered it before I got cranking on the panel too hard! It did take me a while to get it all ripped out, so I've left it that way until I do the swap. I needed to disconnect the sub because the noise it made when playing music was just damn annoying.

I'm only swapping the sub/amp for now. Later on, I will probably run another 4 channel amp for the speakers, but that's for another discussion.

and the JL 8W1v2-4 sub for replacing, the same on ARK used on his writeup. JL Audio 8W1v2-4 Component Car Subwoofers at Onlinecarstereo.com


I'm going with the RF 4 ga wiring kit, which may be a bit overkill for wire size, but I figure it's better to have "too big" a wire than too small and it doesn't cost that much more anyway than say a 6 or 8 ga. wire kit. I've been waiting to hear feedback from everyone before I pull the trigger and order all parts at once from online car stereo.

It seems more of a pain to run the RCAs, but in the end, I think it will provide better sound quality and I'll be happier to do it right the first time and not have to deal with it later.

I'm only going to worry about the wiring for this amp/sub combo for now, but most certainly when I upgrade to a 4channel amp, I'll run ZERO ga. wire to the back, a distribution block, then run separate power wires for each respective amp.

Would you mind linking me up to the right terminals for the battery and chassis? I looked online at radio shack, but they didn't have anything near the right size. I'm particularly anal about my engine bay staying clean and looking good, especially when I run the power wire through the bay to the battery.

Any links/writeups for ripping my dash out to gain access to the HU and hooking up the RCAs for a 2005 Limited?

Thanks for all the help and input, guys!!! I want to make my order today or tomorrow, latest, so I can have everything in hand and make the install this upcoming weekend. :yo:

Yeah, When I make my thread later, you'll see that my ring around the sub that should be connected by glue or something to the sub was just flapping around. 360 degrees. lol no wonder it sounded like garbage.

That combo will work fine as I'm sure you've already read and did your research.

It's not overkill don't worry.

Trust me, it's not that big of a pain at all. Yes, better sound quality and more reliable. When running speaker wire unless 12-14 gauge, it's easy to accidentally cut the speaker wire somewhere along the run.

I'm only going to worry about the wiring for this amp/sub combo for now, but most certainly when I upgrade to a 4channel amp, I'll run ZERO ga. wire to the back, a distribution block, then run separate power wires for each respective amp.

Depending on your overall wattage, I say that 4 gauge should be fine even then. That's what I'm using with my two amps at the moment. Just make sure using the right fuse.

Would you mind linking me up to the right terminals for the battery and chassis? I looked online at radio shack, but they didn't have anything near the right size. I'm particularly anal about my engine bay staying clean and looking good, especially when I run the power wire through the bay to the battery.

When it comes to this part there is a few ways to go about this. You can just use the stock cable and terminal that comes with it and place the terminal between the battery terminal side and the locking nut as usually done. You can get a designated new terminal adapter XB-BTU - Marine Audio - Connection Systems - Power Connections - JL Audio (more work but cleaner). There are others but that's probably your best bet.

For the master fuse block, I'm a fan of blade fuses myself, so I ditched the one that comes with the RF amp kit and used this bad boy. XB-MFBU-ANL - Marine Audio - Connection Systems - Power Connections - JL Audio which looks very clean and modern. I'm sporting a 150 fuse, but there are different amps avail of course. Car Audio - Connection Systems - Power Connections - Blade Fuses - ANL Fuses and no in case you were wondering, I'm not a JL fan boy, I just happen to really like their design, efficiency, reputation, quality, and warranty. All positive experiences and I've done the dance with many audio manufacturer car audio, home theater, and computers. lol

As far as the ground goes, it depends where you plan on grounding your amp/placing your amp. I put my 4 channel under my passenger seat and grounded it to the front left bolt holding down my seat but that required cutting the grounding terminal ring because that's for like an 8mm or 10mm sized bolt, whereas the seat bolt is 14mm. I'm looking for for the right ring terminal but hard to find. I'll look more into it and get back to you. Most ring terminals you can buy separately are either 12mm or 16mm (5/8 & 1/2) I just took the one that came with the RF amp kit and cut the ring into 3/4 circle, so it's like a fork.

Any links/writeups for ripping my dash out to gain access to the HU and hooking up the RCAs for a 2005 Limited?

That's what I used and that was actually the only write-up that was 100% accurate.

BrightLight or anyone else that has info....

You mentioned making sure I have the proper size fuse for the in-line fuse holder. The RF kit I ordered says it has a 100amp fuse (on the box) however in the product description on the site, it claims to have a 60amp fuse. I'll assume RF has the more correct number, but how do I determine which fuse size is appropriate if I'm only running the JL JX250/1 mono amp?

Here's the kit with fuse info:

Also:
my amp can be bridged down to 2ohms yet my sub is the JL Audio 8W1v2-4. The sub manual doesn't say it can be bridged down to 2ohms, but if I understand this correctly, I can still bridge it down because there are 2+ & 2- sub outputs on the amp. Am I correct in my thought process? (if you look closely at the picture, it shows this) JL Audio JX250/1 (JX2501) 2 Channel Amplifiers at Onlinecarstereo.com


Lastly: I ordered the JL RBC-1 remote sub control so I can easily control the bass from the driver's seat. Has anyone had any experience with this/is it worth the extra money? I saw one guy mounted it inside his center console for easy access.

It comes with a 100amp fuse. You determine which fuse size is appropiate with what overall wattage you're drawing for your system. That 100amp will be more than enough for what you're doing.

Don't worry about it, for your sub 250watts is too much, that's beyond what is optimal for your sub. The W1 is safely between 70-150watts; least that's what JL's website recommends.

Truthfully, once you've tuned your amp correctly, you shouldn't ever need a bass controller, that's just personal preference. Sometimes people want more and ease of use to turn up and down to show off and whatnot. Totally your call. I don't have one with my amp.
 
Question regarding RCAs: how imperative is it that I run the RCAs separate from the power wire to the amp? I was going to run them next to each other for a foot or two then separate them once I've got more room for wire placement.

It's tough threading the wires under the carpet, even with a coat hanger. I want to avoid any engine noise during acceleration with the RCAs and I know that can occur if they are run next to each other. Although, this amp is only for the sub, so not sure if it makes any difference....

Thanks!

I had noise and first for like 2-3 days and all gone now.
 
Couple things I've noticed with my setup so far:

Just installed 12sq feet of dynamat today all over the sub box, plastic panel, and behind the box on the truck's frame. Just like it was done here: http://www.toyota-4runner.org/4th-g...dded-amp-install-pics-info-11.html#post726266

I haven't put the plastic panel back on yet since it's such a pain but I honestly haven't noticed any difference in sound (rattling) since installing the dynamat. Others have said they noticed a difference. I'll give it a few more days....
Not sure if putting the plastic panel back on will make it "sound" any better and reduce the rattling or not. I've had it off for 3 weeks now as I was make the changes to it.
Anyone have any input/suggestions for this issue?


I did NOT seal the spacer ring to the sub box, only ran the 8 screws through the sub/spacer and into the box. Not sure if this would be the reason that the sub sounds "hollow" when it's hitting. It may just be me, but something doesn't sound right when it runs during the music. I haven't adjusted my amp settings a whole lot just yet, but can't see how/why that would be the issue. Would it help the sound at all if I sealed the spacer ring to the sub box?
