    I would like to add some subwoofers and an amp to my 2006 Sienna CE. I'm wondering if this can be achieved with a custom wiring harness as I've seen them for other Toyota vehicles or will I need to buy a new after market head unit as well? When replacing the head unit with an aftermarket one...

    Ongoing project. 2016 Sienna XLE non-JBL Upgraded stock speakers (not the dash yet). Went with Kicker 240w 2-way 6.5” and 360w 3-way 6x9s. Used plastic adapters found on Amazon for the 6x9s. I used the stock mounts for the 6.5s. I just had to rip out the existing OEM speaker first. Sounds great...

    Hey all, I'm looking for some input from fellow 2018 Sienna owners who have the JBL stereo. On our van, it seems like the bass only comes from the two 6x9s in the front doors. It does not seem like the subwoofer in the tailgate does anything, even with the bass turned all the way up. If...

    I'd like to present my subwoofer project in my 2014 Sienna. The goal of the project was to get a maximum possible sound upgrade without losing space in the trunk. I decided to build a cabinet to get as much volume as possible, so that I have more possibilities in the choice of the subwoofer...

    Hello, I've read and read and read, but can't find where to get at Left/Right speaker signals. It would be preferrable to have line-level, but I'm under the impression that that's not available anywhere without breaking inside the radio - which I'm not going to do - so LR speaker levels will be...

    I have a 2004 XLE LTD with JBL and without Nav/DVD. As seems pretty common, the subwoofer has blown and I am in the middle of replacing it. I purchased a Kicker 8" sub with the correct 4 ohm load. This is a dual voice coil sub and so it has inputs for 2 sets of positive (4 total) and 2 sets...

    I have for sale a custom box that we built for the 3rd row seat storage cubby hole in 2011 Toyota Sienna. Built out of 0.75" MDF. Should fit 2011-2014 Siena models. It includes a brand new JL Audio 10TW3-D4. The speaker is about 2 months old and I have the receipt (one year warranty). There...

    2004 JBL Subwoofer Replacement The subwoofer on our 2004 Sienna XLE is muffled. I assume the subwoofer needs to be replaced. I know they make a repair kit for it, but does anyone know an aftermarket subwoofer I can replace with it?Im sure there must a subwoofer that someone has replaced. Any...

    Ok here it goes, my sub was blown (crackling and distorted) So I replaced the Sub. (old factory sub was a 8 1/4' DVC Sub. The Sub I'm going with will not work on factory amp. So I'm adding a new amp for bass alone. What I need is the schematics for the stereo wiring! Mainly the rear speakers...

    Trying to improve the bass sound of the stock CE sound system, non JBL, i see the empty location where the JBL woofer is installed in the XLE models, I also see the male connector is right there hidden behind the plastic panel, removing the little light/switch unit above, I wonder if I can make...

    Having a really tough time trying to fit some speakers in the rear locations. The OEM paper junk Toyota equips our vehicles isn't even worthy of being a paper weight. It is super shallow that even shallow mount speakers out there won't fit ??? SOLUTION: Fabricate custom pods that will protrude...

    I have a '98 LE, and want to install two 10" or 12" subwoofers in the back for some extra bass. I don't want to lose space by putting them in a box. Any ideas for a "hidden" or stealth subwoofer install? Thanks! Patrick

    Hi. I'm a spazz. I can barely change a lightbulb, and every time I try to do "custom" stuff to my van (like wash the inside of the windshield) it looks like a 5-year-old got some paper towels and went wild. The reason I ask this is that I would like to customize my van, but I simply don't have...

    Frankly put, the subwoofer (and driving amp) suck on the 2008 Sienna. Any sort of volume overdrives it to distortion. I have to adjust the base all the time to prevent this. I am guessing this is also why I have seen other posts saying they often blow. The other day it didn't even come on...
