I am in the process of looking at upgrades to my cd stereo in the M and saw a really nice
sub woofer 10" and cabinet that fits in the left corner of the trunk. Ok so whats the plan
as far as wiring and routing them to this part of the trunk ? the car is soft top 91...
If you have done this before please chime in....
jake :clap:
All you need to run is your RCA cables since your battery is in the trunk. I ran my cables on the drivers side since I put my self-powered subwoofer on that side. There is lots of info on miata.net about buying and installing subwoofers.
I used to hang around miata.net alot - Not so much anymore! They got way to picky for me...
Wont hurt to look at some verbage though....

I ran wires down the passenger side just so I could have easier access to the tunnel at the front corner of the trunk. I guess it works either way!
(...and one of these days I'll finish that project too!)
bmcreider, forum member, installed a 10-inch subwoofer in the drivers side corner like you are proposing. you might send him a PM about his install.
I probaby would have run mine down the passenger side, but the TCB Wally Mart cables I bought were only 12' long. You really need 15' of RCA cables.
Thanx motorollow ! I will be asking around the site for details. I'm picking out my new head unit to go with the sub. Looking at the kenwood KDC 238
I think it is. It fits the opening and has 22 watts RMS power plus Sub out put, I have a similar unit in my frontier , power and quality sound is awesome
With 6.5" front speakers.
I am looking to add a sub also wondering wear you saw the left side enclosure for the trunk? I already have an amp, some component speakers, and a new headunit I just have to pick out a sub and enclosure and wire it up but I can't find a good place to put it.
I saw the enclosure on the crutchfield web site. There are others too. Just do a search for subwoofer for miata. Should net something.
If I can find the exact one I saw for the 10" woofer i will link you up.

I saw the ebay one but from what I can tell it is a perfect fit for the NA but wouldn't be so snug in my NB. I may just build a box instead of trying to buy one, that way i can take up as much or as little room as I want.
The trick to building a sub box is the total volume inside in square inches, or cubic inches. It needs to be a certain size for each different sized speaker.
Most times the premade boxes are all figured out. No slide ruler needed or math degree to figure it out. Just buying all the individual components and then
having to do all the labor and soldering takes time. I did find one for both na and nb cars if you want to hook up with him let me know...
I will have mine soon i can send you some details on the exact size of the box. It comes with an acustic audio 10" sub speaker.

cool I would appreciate it. I already have sub picked out that I found a really good deal on. It is a 10" kicker solo classic normally about a 250 dollar sub that I am getting for much much cheaper so my box needs to be about .66 cubic feet.
I will be starting on the mods to the system this week. the rest of my parts will be here tomorrow.
Will take some time to get all the ring terminals, crimps, fasteners, ect. I'm going to make a nice
mount for the jvc amp in the trunk. Should be cool. I already removed the spare tire (donut )
Cant use it anyway.

Good luck!
Well Here is what I came up with. Amp is located behind the passenger seat.

Finished custom sub box today and I am really happy with how it turned out.

Wow, that's a BIG enclosure.
yeah it takes up about a 3rd of the trunk, but it is nearly 1 cubic ft volume and sounds just right so I was fine with the loss of space.
What are you doing to control battery drain ? I here these subs and amps will kill the little sealed battery in no time ....
Is this where we get to experiment with Capacitors ? Or go bigger battery ? The stock 91 alternator is how many amps?
Currently will be running JVC 20 watts RMS x4, pair of Sony Explode 5 1/4 " , JVC 130 watt bridged amp and 10" Acoustic Audio Sub. Not sure how much drain i'll see in this setup what do you think ?

Frys electronics sells a capacitor that they have on sale for $30 occasionally. I had to buy one for my son's Civic to keep the lights from dimming when the sub hit hard. Easy install, but the capacitor is rather large.
How do you know what size capacitor you need for the system ? It could be 1 microfarrad, 0.1 microfarrad, 10 microfarrad.
So how do you figure this part out ? I have access to a store that sells surplus electronics. I take it this is a storage capacitor.
It stores the potential energy and releases it when needed. So to speak...

Sub looks good Kylen, It does take up a good portion of your trunk. I will post some photos of mine when it starts to come together.
My wiring harness just so happens to match the cars colors of white and blue. Should be good to go here in a few weeks,.

Luckily I have a friend who is a car audio installer so he helped me out tremendously. He said a capacitor wouldn't be necessary for my setup which is 360 watt 4 channel amp, Component speakers, 10" 4ohm sub.
Mines much smaller so I think it's overkill myself. Several people at work too said I don't have enough overall consumption of power to need a capacitor.
I agree. I'm going to run what i brung and see what happens. Luckily I have a battery voltage monitor on the dash to keep track of output and if it starts
to drop too low I will know when to nix the power robbers ... I think if I keep it conservative on the amplitude it will be fine. Trunk rattling bass is not what
im looking for. A pleasing thump yes. I'm even going to try to roll with the stock headrest speakers to start out and see what sparks fly. I hope they
hold up to the new amp and head unit.

Installation is now completed, Turned out ok. So far so good. I was able to install the subwoofer in the left hand corner of the trunk
and the amp is mounted vertical in the back of the trunk just under where the hinges would be inline with. I wanted mounting that
would still keep most of the trunk space usable. I did remove the spare donut tire. Up in behind the spare tire mounting area
is a spot for an umbrella or small set of clubs. I cut a hole out of this portion to allow the sound from the subwoofer to enter
the cabin area of the car. This also allows for the wires to enter and run to the head unit. The bass reflex port is just behind the
upper portion of the passenger seat. With the seat pulled forward an inch or so makes a huge improvement in sound.
The bass notes now can travel into the cabin without high volume. A nice touch. I will post photos soon.
