Hi guys/girls,

Im in need of boot room. Just took out my twin 12" subs which obviously took up all my boot space. As you can imagine the sound system is now CRAP.

Saw there is a spare tyre. Can I remove the tyre and cut a hole in the cover panel and just screw 1x 12" sub there.

Can anyone let me know what work will be required.

Thanks

depends... on lots of things...

under the rear tyre is a little notch that sticks up to keep the tyre in place, the sub might be too big and foul on it.

it will sound like shit unless it's enclosed in a box, so you would have to make that fit the space

What most people do is make a false floor, basically just make a box that fits in that area and raise the entire floor up as much as need be.

It is quite a lot of work to do it right.

how much would i be looking at for a 12" sub box to fit in side. Just wanting to keep cost as low as possible as im strapped for cash atm. Would it be worth selling my sub box but keep my subs.

Its a pioneer, outside of box has carpet stuff all over it. Aluminium or metal of sorts trims. Inside of box is lined with a cotton foam material.

the fibreglass corner boxes are crap, they sound bad and they're expensive.

i've seen a few fits done where you cover the wheel well in alfoil/glad wrap, and then fibreglass over it, and layer dynamat in the fibreglass and make a sort of bottom for the box, then build a false floor and sikaflex it on to the bottom section....

either that, get over it, you've got a skyline, its not a family car, stiff shit if there's no boot room, go buy a commodore if you want boot space...

i can actually fit both subs where the spare goes. they sit about an inch or so above the wheel well, will this be a problem being magnetic????

my plan was to use same material that is inside my sub box (cotton fluffy stuff) and line the wheel well, then cut 2 holes in the tyre cover to fit subs and sikaflex + screw tyre cover back down. screw subs in and connect.

The boot already has dynamat throughout the boot lid and i have the stock card boot lining things.

If it sounds real crap then i can just put the sub box back in and have no boot once again since the sub box will cover my 2 holes i will cut.

What difference will it make if i face my subs into the car, as they now are facing out of the car????? (meaning turn my box around as this will create a little more room)

My skyline is a family performance car....lol, fits shopping luggage gets me from A to B FAST and has a good sound system.

if Fhrx Studios recommend and install these in their sound wining cars and not being to exy then they do sound good.

im not sure where you heard corner boxes sound bad but if its a home made job of course it will not sound good

imo skylines have a decent boot and a side box would be perfect for what his guy needs

thanks 08r3308 i think i will get 1 box and put to the side. any rough idea of cost for box...i will install myself.

since im only running 1 sub, will it sound better. the car came with both in it and if my reading is correct I have a 600W amp and 2x 1000W subs (400W minimum) the sub box only had 1 speaker cable to the amp and then it run another cable into itself. im presuming it split itself so both woofers running but through 1 amp terminal.

face the subs towards the numberplate, will gain a few db from rear loading them.

mm sure... i've retailed the fibreglass boxes made by innovation audio on the gold coast. they sound really bad, as the fibreglass flexes, and defeats the purpose of a box all together.

never heard a good sounding fibreglass box. ever.

thanks 08r3308 i think i will get 1 box and put to the side. any rough idea of cost for box...i will install myself.

part number of subs and amps would help.

there's your problem right there (innovation audio) , not all subs are suited to one box.

maybe you should get yourself down to Fhrx Studios and you can hear many , because that guy does wonders with sound.

      A locally delivered Infiniti have remote start installed but don't come with the remote start key. You need a new remote start key and they just need it programed. And this is different to making/programing a new key that just starts the car.

      Cheers, and cheers for sharing so much of the build and also sharing the glimpse of what turns out to bring a lot of us poor decision makers together haha.  I do recommend learning more about how to manage it, if not considering getting a  formal diagnosis.  The discussion with the psychiatrist I got my diagnosis through was quite eye opening, things I'd not even considered to be ADHD related and hadn't mentioned were things she asked about out of the blue and were common themes with people with my flavour of ADHD.   It's not a label for people who are hyperactive and ill-attentive, there's more to it than that and some of it can be much more challenging or damaging - though there are of course two sides to the thing, and a lot of the stuff we have to go through and work on to live with it make us effectively "better" at other things as well. Aside from the fact that there is some argument I could have a bit of ASD seasoning in there (came up during the diagnosis, and neurodiverse things seem to not stay as a cookie cut) I suspect you need to learn more about ADHD if you are puzzled about how hyperfocus could possibly apply.  I *do* personally use "superpower" with quotes deliberately, but it's 100% an ADHD thing due to the exact reason that lack of focus is also an ADHD thing... Loosely speaking the inattentive side of ADHD isn't the inability to focus, it's the inability to control where the focus goes.  Not being able to sleep because brain is more interested in thinking about a stupid thing I said to a girl I liked 30 years ago, not being able to focus on work because my brain is more keen on putting together the torque management strategy we're going to try out with a drag car next weekend, not being able to focus on a conversation with someone I WANT to listen to and respect because there is a flickering light in my peripheral vision.    If I could just stop work and build the torque management setup right there and then I'd not hear anything else until it was done.

      Maybe you should do some more reading.  Google positive effects of ADHD and you'll get your answers.  One of my personal downsides of ADHD has been talking before I think.   Maybe you have it too?

      Excuse me for butting in....but which part of ADHD can be considered a superpower? I would have though it far more likely that some ASD comorbidity is more likely to be contributing to an ability to hyperfocus on something. ADHD being aimed somewhat in the other direction. My shed looks like your shed. My whiteboard list of unfinished projects has entries going back 15 years. I know what you're talking about - I just struggle to connect ADHD to the results being discussed.

      Thanks for reaching out!  It's a blessing and a curse at the same time.  I'm undiagnosed but it doesn't take a rocket scientist to see it in me... I have more half started projects laying around my house, shed, garden, etc taking up space and money, destroying aesthetics than if I added up all of my mates projects together. But, ADHD gives me the ability to hyper focus on things that no mere mortal could even  comprehend.  A recent pool build is an example of that....  I dont know anyone else that would be dumb enough and focused enough to take on then complete something of that magnitude. I call ADHD a superpower but it can equally be completely destructive if not controlled and focusedon the right places. Addiction is a major concern to ADHD people and thankfully my addictions have been no worse than projects, XBOX, chocolate and being an arsehole! It's often hereditary and my 13 year old son is currently learning how to drive it at the moment. Keep lurking! If i can finally finish this bloody thing at some point it will be a win for all of us ADHD'ers! 🤪
