idea for the sub placement

[warhorst]

hi, i posted this on another forum and decided to post here as well.........what you guys think???

my ride is a 07 yaris hatchback......i would like to install a sub in the back but would like to preserve the space. so the idea is to install the sub(maybe the a slim series ) in the hatch itself. if the 10 inch slim series does not fit...then maybe an 8inch sub.

which basically is to remove the panel on the hatch and devise a way to fabricate a new panel on it. i know this sounds nuts but its just an idea.

my concern is that i do not have enough clearance for the sub since the back wiper will have some connections there.

another is that the weight of the sub are usually around 8pounds and up so once i open the back hatch, can it handle the weight and not close back down?

if you guys still dont understand.....well its the rear "door" that i am trying to install in.

also i am trying to find out something that i saw on MTV's car mod show......its a automatic fuel tank cover that open up to the side mechanically....and when open, the fuel cover is parallel to the body of the car.....normally our fuel tank cover opens up on a hinge and is perpendicular to the body......hope this is clear...lol

thanks

I guess it would be cool to have the sub in the lift gate (whatever you want to call it) but it will be a lot of work and you certainly want to reinforce it so it doesn't have massive resonation...I'm thinking and just guessing it wouldn't be thick enough to put a sub in there
You can always put it under a seat, yours or seats in the back, if possible, I know people do it.

well at least its a pretty cool idea......was thinking about the idea for fun and for more practical solution is of course down the seats........or sacrifice the rear space.........and for the subwoofer to be used ....was looking at the pioneer slim sub ts sw2541d

however i will not be looking at very good sub performance. just an idea that is worth a try for the rest of the ppl here.

lets assume that i pursue the idea, what other advice will be good.....lets keep the idea goin.......cause if it sounds doable, i'll try it.

probably first to remove the panels and look at the clearance.....is it possible to change the 2 struts support for handling heavier loads?

I agree with you its a awesome idea and if you're not looking for mega bass but just a little extra kick there might be some hope! If you know how to take a part the panels and what not, I would look into that and measure it also find a sub and measure that as well and maybe figure how you're going to mount it. For the struts, I'm guessing their obviously specified for that lift gate configuration...but maybe go to a Toyota dealer and ask about it? Or go to a audio store and ask their opinions if it might be do able or if other people have tried it maybe not with a Yaris but the concept of the sub in the liftgate. Good luck!

Cool idea, but it's already a standard option on the Dodge Calibar. I was vacuuming out the 07 5dr Yaris today and there's tons of unused space under the seats.

In my old Civic Hatch, I had a 8" Bazooka subwoofer with an 100amp built in amplifier. Darn thing sounded amazing in the hatchback and gave be problem free usage for 9 years (I regret not taking it out when I sold the car). Anyways, I think 6" bazooka or 2 of them might fit under the rear seat.

This week I am going to start work on a fiberglass sub enclosure that actually fits inside of the spare tire (not the spare tire tub but the actual tire itself) This is in a liftback model, I am going to use the common method of building a fiberglass enclosure by using chop strand fiberglass mat, I will outline the inside of the spare tire wheel with duct tape and cover with carnuba car wax (paste form) for the release agent, While also building a small wedge shaped frame (cause the tire is at a slant in there) on each side of the tire This will all be level with the original floor panel in the rear, Both sides of the sub (10" sub) will be the amps and a crossover, This will all be ran off of the stock head unit ...I know this will erk alot of hardcore stereo fanatics but the whole principle of this idea is total stealthness, not show quality performance! I will also be running 6 1/2" 3-ways in the doors and modding the rear side speaker area for 6x9'S (fitting a custom screen flush with the plastic side panel simular to stock) Everything will be very stealth. The sub requires .70 cubic feet of space for a sealed enclosure and I can slightly exceed this, I used styrofoam beads in a pre-measured amount that equaled .70 cubic foot, outlined the area inside the tire with plastic and filled it with the beads to estimate the space, I believe that if it is done right you could maybe fit a 10" sub with a higher required volume in here also. I will post pics in progress later

hi bugnuts.....that sounds doable......and i hear you on the performance......what i trying to achieve is basically add in the lows.....and voila.....music gonna sound alot better......and also preserve the boot space.

so the panel covering the spare tire be removed and u gonna use some sort of fibreglass/mdf board for the holder for the sub and amp......am i right?......so will the rear space will be sacrificed then?

also before u work on it, remove the spare tire......u will see 4 rubber gromet that just pops out easily and reveal the road surface.......i am always paranoid that the gromets jsut gonna fall of and get water...dirt into the tire enclosure......so i lined it up with trash bag and pop the gromets back.

maybe you can add sound damping material on the bottom of the spare tire floor. to prevent rattling of the sparetire.

post some pics on your progress......would love to see it.

well i can always use a sub under the seat....but we always want to be differnet.......individuality.....lol....

also if you need help in removing the HU panels and other side trims........another forum site has got some guides available for downloads........not sure if i can post other links to forums but remove it if you like mods.

That's right the original plastic cover back there will be replaced with something like mdf with carpet covering and when the hatch is opened everything will look normal except for the grill in the middle with speaker material covering it (I am going to do something to camoflauge it also), I am a bit concerned about the rattles as you spoke of though. Your idea may just work with the sub in the lift, you would probably have to boost the lift cylinders and dyno the hell out of the inside of the lift (it would probably turn into a big echo chamber! I will get some pics up when I get started. On Yarisworld.com there is a link to a complete yaris manual from cd (The service manual)

there is enough room in the passenger side of the dash for an 8" sub, lots of 'glass work but it could be achieved. Good use of otherwise dead space.

Been busting my ass on my ICE setup in my liftback since friday, I started my project with a totally new idea..I have fabricated a sealed fiberglass enclosure that is actually formed inside of the spare tire itself and not just the well were the tire goes, This allows for me to have the spare and a stealth system in the rear storage area, The only loss from doing this is the two small storage bins on each side of the tire and this is not much of a loss anyways. Well here is what I did: first I built a frame around the tire comprised of 1/2" mdf board, Then I covered the tire in aluminum duct tape (This was a mistake and I will get to that later), I needed .70 cubic feet for my sub so I set up everthing with the tape and filled it with styrofoam popcorn (this was a pre-measured amount) the sizing was perfect and I probably could have got .75 cubic feet from it if I tryed, I then started laying in 1.5oz fiberglass matt with the resin (chopped sections about 8" square) and some strips also, I ran the matt up the insides of the mdf frame but not over the top (this is because I mounted a top piece with the 10" sub in it) after two to three layers had set I attempted to remove the fiberglass from the mold (the tire), This is where everthing went bad! It seems that the resin had leaked a bit through the tape and was between the tape and tire, I ended up having to brake the plastic hold down for the tire and remove the fiberglass box and tire together (yeh I felt like a moron!) Well after about an hour of prying the two apart it finally popped out in the form of a perfect cast, I then placed about two more layers of matt and resin down to end up with a thickness of about 3/8", I built some platforms off the side of the box to mount the 3 sony amps and eletronic crossover (ebay,rummage sales, and freebies), I ran everything off of the stock head unit with a line output converter and replaced the front crapass speakers with some clearance sale $20 kenwood 6 1/2" three ways, and the rear crapass speakers with sony 6x9 three ways (which I already had setting around), By the way if you decide to put some 6x9's in the rear side panel of a Yaris LB be prepared to chop some metal..Cause they don't fit! All together I spent about $50 on supplies and about $120 on equipment, This is the budget buster system. Although it is not completely finished I wired everthing up and it sounds amazing! I am not at all new to car stereo systems (about 20 years now) and this is the first time that I have used the stock head unit, And I have to admit that it is not bad at all plus I still mostly have retained my stock appearance and that is the best part, The only thing that gives up the stock appearance is the 6x9's in the rear side panels and I am planning to place them behind the plastic panel with a custom flush fitting grill...but later. Probably the worse part of the whole install was trying to run the main power wire from the engine bay to the rear, I achieved this by using the small rubber grommet that the hood release runs through, I was able to fish the wire along side the innner fender driver side and bring it right up near the battery. I have posted some pics although it is not finished, I still need to mount the amps cover the eclosure with box carpet, mount a grill over the sub and cut the cover that goes over everything (it will be 1/4" mdf cover in carpet also). When everything is finished the hatch area will look stock and function just as before the mod but will only have the 10" grill in the middle + I can lift the whole thing out and get access to my spare if needed.

[warhorst]

So how does it sounds?...have you finish the whole project yet? also does the 2 side "panels" beside the sub enclosure stick to the body of the sub enclosure?

[bugnuts]

Finished up the system with some speaker box carpet and spray glue, Topped it oof with a 1/4" mdf board cover (covered in carpet also), Everything turned out good and it sounds great too. The stock head unit is doing a very impressive job with the quality of sound (sfter getting rid of the rest of the junk equipment!) So here are the finished pics..
