Casey Bones Nice write up. Slowly in the process of designing my system also. Can't wait to get back home next month and start the build.

Steampunk Hey!

Was out the last week or so, but managed to return to the install yesterday....

Got the hard top out and got to the soundbar.....I thought it had 5.25" speakers, but it seems to have a 4" pair (2-way), they are some off-brand, but seem to be beefy and have a quite large magnet for their size.

Ran new 14 Gauge cables from the soundbar, along the rollbar (covered by the wrap thingies), then into the original wire cover on the inner side of the jeep, then down to the drivers seat area.

Next up was final bolting of the console to the floor....drilled holes and bolted it on. Then filled sub cavity with the polyfill and screwed shut the 'false floor' on the console that basically seals up the sub cavity and gives me the new surface to hold stuff inside the console.

Still pending are the front and rear amp block plates (should get those cut and welded today), and final amp install onto the seat / seat bolting in place.

But, being the impatient kind I am....I wired everything up yesterday for a quick test-listen inside the garage.

First impressions are it sounds great!...the small pair of speakers on the soundabar seem to put enough sound (quite close to the ears) at this point, and those small cheapie speakers sound great amplified (well see if they last).

Most noticeable is despite the thin metal of the console it was able to produce quite a significant amount of bass from the 8". That Infinity sub really came through. I've had Infinity before and they've never let me down, the little sub just sounds awesome, and considering it was $48 bucks, its a downright steal!

I expect to have everything buttoned up and ready for a test cruise by the wekend, and will post some final pics then.

Later!

Steampunk Hey!

Remaining now is the ground connection....this will be strapped from the amp to one of the seat screws that go directly to the tub....I ground away the paint on the inner seat bracket where the bolt goes, and cleaned the bolt threads to assure a good ground connection....

So now all the cables needed to feed the amp are in place.....

Next steps are to remove the hard top, in order to easily get to the sound bar and prepare and route the speaker cables that go there.....

The cable going to the center console (sub) was cut and terminals crimped on...

In the next few days I'll weld up the under-seat front and rear panels that I'll use to cover up the amp from the front and back (From eyes in the front, and from toes from the back)....

Steampunk Hey!

Further back on the original loom there is a 'drop' for a cable that goes to a seatbelt sensor....I ran an additional drop from the 'new' loom at this same spot, to drop in the power and remote turn on to the under seat area.... used the original tabs there also to hold the now 2 looms.....
03-10-2013 09:09 PM
Steampunk Hey!

Thanks!....yep, as I said before, Ive always believed a sub in necessary for proper full range music reproduction, and so Ive always had them in my rides....

But Ive also always had only one sub....never really needed more...., the largest Ive had is a 10"....I believe any larger sometimes muddies up the sound and are less quick /articulate with some of the tighter stuff (Due to larger mass, heavier / slower cones)....

Anyway......I got a generic amp install kit (Wallyworld) that is not the best, but sure simplifies things!

Routed 4 Ga red power cable from the battery (Fusible link immediately after battery)....into cab through a small hole I poked into an existing rubber boot (its the one on firewall between valve cover and brake booster).....cable runs over parking brake assembly....and was wrapped on slit convoluted Poly tubing (Wally as well) along the side of the inner tub, joining the existing tubing there....(This tubing also contains the "remote turn on lead" from the previous post)...

The RCA music signal cable was routed from the "Master volume pot" in the dash...also behind dash, and along inner side of the tub, but this cable was inserted along the EXISTING convoluted tubing already there, the one that carries the taillight cables and such. (To keep it separate form the heavy power cable)...

Used the original bendable tabs to hold the looms along the inner tub...both looms fit and are held perfectly...
03-10-2013 08:56 PM
Steampunk Hey!...thanks for the kind words!...

Ok so while I get done with the amp-concealing panels, I did some cable routing today....

First I installed a pair of switches on the blank panel in the dash...one is not used at this point...the second is needed to turn ON the amp, since there is NO head unit with a "remote" turn on lead, the amp needs to be turned on manually......I crimped a spade onto one end of the cable, and that goes to the "radio" empty slot on the fuse box (See small blue wire, lower left)...this slot on the fuse box has power only when key is in the "On / run" position, so all is good (Verified with a multimeter to be sure)...the other end, of course goes to the switch, and then to the amplifier. The switch has a ground lead as well (lit switch) which is ok so I have a nice lit blue switch as visual indicator when the amp is on....

Later!

charleybrwn13 This looks like a nice setup and I like that it's stealthy. Subscribed.

I like that you went with an 8in. I just put 4 8in kicker solor barics in my jeep. I may have gone a little over board but Godsmack and Metallica never sounded so good!

4Left This thread is awesome! Great job, I am jealous.
03-07-2013 03:57 PM
Steampunk Hey!

In order to install the right angle iron piece in the front, I will have to use four of these "Right angle RCA adapters"...and the cables will the come in from above....(Inputs are the 4 RCAs on the front left of the amp) this should totally block the view of the amp from the front....
03-07-2013 03:44 PM
Steampunk Hey!

Ok......so I temporarily bolted on the seat to see how it looks...even though I run half hard doors most of the time, here it is without doors.....

Looking from the front (fender) the amp is slightly visible......

Looking from the rear it is almost invisible, unless you hunch down a bit.....sitting behind the drivers seat with my big feet down.......dont hit the amp....

I'm thinking I will add bolted on pieces of 2" or 3" angle iron to the front and back hanging brackets (Same hols used for amp mounting) to completely make the amp invisible even with no doors....
03-06-2013 05:25 PM
Steampunk Hey!

Ok, the seat bracket holes were covered with the welded on strap metal and painted.

The amp will be mounted on a hanging tray made of two sections of 1" strap metal that was cut, bent and welded to the inner / lower part of the seat rails......the wood part is a template of the amp so I could get the correct spacing on the straps when welded .....


Ill post a better pic of the mounted seat and amp later tonight....
03-06-2013 12:51 PM
kawika95 Any finish pics? i have a yj and am trying to setup a new sound system!!
03-04-2013 09:52 AM
Steampunk Hey!

Ok...moving on to mounting the amp.....it will be done under the drivers seat.......but since 'stealthness', and difficult removal is important, I will do some mods to the seat brackets.....

I picked up a section of 1/8" strap steel (3") from the hardware store, and cut it to fit the seat brackets.....these will be placed inside the brackets, and welded from the outside.

The idea is to partially cover (One side) and fully cover (The other) to prevent the amp from being visually obvious.....the amp strap mounts that will go from one side to the other will be welded to these plates.

After all is welded up and ready, amp removal will only be possible with seat removal, or a lot of time and space to unbolt with hands going in from both front and back of the under seat area....

Steampunk Hey!

Ok, since the sub is now mounted, I filled up the box with some polyfill....(Box ended up slightly under the recommended sealed size due to internal wood used)....so the polyfill should help.

The dividing board (which effectively separates the bottom sub chamber form the top storage chamber of the console is on and ready to just be screwed shut....

As can be seen, the storage part of the console remained of a decent size...
03-01-2013 09:42 AM
Steampunk Hey!

Ok, so I drilled and cut the console to mount the sub....unfortunately there are spot welds on the bottom part and a few broke loose due to the vibration and tugging of the metal blade on the jigsaw.....had to take the console somewhere to get those re-welded....

The interior of the sub cavity on the console was caulked up with silicone.....

Wooden parts to achieve division were bonded and screwed to the interior of the console....

Finally sub was mounted, and the console is now ready to go into the YJ....I post a pic of the console mocked in place later....

Spider 007 I like this setup. I might use a variation of it when my project comes to life...
02-26-2013 10:49 AM
Steampunk Hey!

Cut line marked.....sub mocked over it.....

Steampunk Hey!

I'm using a Smittybilt stereo security center console, in order to have some better secured storage.....dont know how this compares to a Tuffy, but appears somewhat rugged....anyway, I never carry valuables in the Jeep, so it'll work.....the center armrest and cupholders are nice too......I might use the 'stereo' cavity in it for a CB......

Anyway....here's a shot of the console, with sketching of the interior space, and how I'm working on separating it into two cavities, to use the bottom part as the box for the sub.

The infinity sub requires a 0.35 cuFt box behind it (Sealed). So the separation where placed resulted in 0.37 Cuft, so all is good.

The top part of the cavity will be used as intended (lockable storage)....

The bottom mounting makes the sub almost pretty much undetectable....
02-26-2013 10:14 AM
Steampunk Hey!

Im installing the sub in the center console.....firing downward......Im doing a modification right now to divide the inner space of the large cavity for half of it to be the sub box (lower half) and keep the upper half as storage.....Im making a sketch of it....

BC Dony....I actually thought of just *putting* a bunch of cables in there hanging out to get the 'no radio' look...jajjajaj....but the switch panel is a great idea, I might just do that....I also believe someone sells a metal safety drawer that goes in the radio slot....dont recall who sells that.....that would also be an option...
02-25-2013 08:51 PM
BCDonny was wondering what you are going to place in the slot for the stock head unit? Might make a good place for a switch panel

Steampunk Hey!

I do have plans to detail the amp mounting (Also will be stealthy, protected, and will not take storage space).....unfortunately my brother (and his welder) are inaccessible for the next two weeks.....so at this point I will skip the amp installation, and temporarily move onto the subwoofer install....

Later!
02-24-2013 09:23 PM
Steampunk Hey!

Ok, the amp is here....I decided on a Jensen 4 channel amp (Power 760.4).....I have had good experience with Jensen amps for everyday use on Jeeps.....(No, they will not win any audio quality contests, but I find them a good option for an open top Jeep) and are a good bang for the buck.....

At this point I will only run one pair of 2-way speakers (in the overhead sound bar), on channels 1 and 2.......channels 3 and 4 will be bridged (output combined) to feed a single subwoofer.

Sincce its a 4 channel amp, I need to feed all four channels, so I got a pair of RCA female to dual RCA male "Y's".....hookup is as shown.....
02-24-2013 07:04 AM
kywaterman Looking good I figured you were gonna wire into the amp somehow. Now days with Ipods you can do way more that a headunit, find ya a touch and you could download movies or you could hook up an Iphone and stream movies will listening to through the jeeps speakers. This seems like the best bang for the buck, in my dd my head unit has a usb port, my ipod never leaves unless its time to add more music, and antenna that dude got took off immediantly
02-23-2013 11:23 PM
Steampunk Hey!

Ok, so the volume control is painted black and mounted.....from this, I connected the male to male RCA cable (12 ft) that goes to the amplifier....mmmm......amp should arrive anytime now.....

Later!
02-22-2013 05:17 PM
Steampunk Thanks!

Ok...the inline volume control was painted black to make it a little more discrete....and is now mounted to the grill fascia......will mount it on the YJ later today and get an updated dash shot........

Later!
