What do do with 3 SA 8's Soapbox Honda Fit

[Soapbox 7]

In one of my intro threads I remarked it was like an old addiction. Seems as of late well for over 13 years I've mended my ways and laid down my desires for my family. What started as just a small system has resurrected the monster. I have a few goals intended for this system they are:

1. Create a clean install which is removable with minimum effort. After all this is our family car.

2. Target db level 145

3. Modular design to accept several boxes and yet remain SANITARY in installation.

4. Kid proof Covers to prevent kids from dropping stuff in ports (one reason the passive radiator is one of the designs)

5. Design for double the electrical draw.

On hand purchased items:

1. Honda Fit

2. 2 Optima Yellow top Batteries (one in the engine bay, one below box.

3. 40ft of Knu Flex 0 gauge cable

a. I've made all of the cables just need to install

b. 3 ground straps

* 2 body , 1 engine

c. Positive 2 cables

* Alt to Battery, Battery to 180 amp fuse knu koncepz the nice one

d. note on all the lugs I used the normal boot but then also heat shrink

4. XScorpion 3 way lug terminals

5. Kicker dual ground luge for rear of car.

6. Sundown SAZ 1500

7. 3 8" Sundown SA-8's Dual 2 (actual is 1.63 approx for a final ohm load of 1.08)

8. One box made for 2 8's in case I want to run @ .5

* 2 cubic ft slot ported to 33

* this box is finished needs speaker hole cut and subs to arrive.

* finished is textured satin black.

* all inside corners 1/2 round

9 Second box for 3 SA 8's

*3 cubic ft dual slot ports tuned to 40

*Box needs closed and subs

* Dimensions for modular set.

10 Third box (Not Completed)

*3 cubes truncated prism 3 SA 8's and a 15" PR

11 Forth Box Designed completed

* T-line for 2 8's

12 Fifth box 3 cubes tuned to 30 hz Kerfed port Design completed

Items needed to complete install.

Subs paid for just not here

Install big 3

Install processor and run RCA's

Order nice RCA's

Sound Deadener most likely SDS tiles and foam. This car has horrible road noise currently.

At this point I will evaluate the front stage most likely I will finish it out with Sundown and Jl audio.

An overview of design concept is as follows. In the Fit the back seat leans back from vertical approx 8-10" the wife agreed I could have from the back of the seat vertically 11". Therefore, most of the designs are narrow boxes which are 35- 36 inches in length. average depth is 16". The amp rack will support the boxes which will be drop in style and secured down with tie straps NOT okie joe duct tape they will be secure and undetectable as removable. This should give me a triangle in front of the box 10 x 16 to lay a battery or 2 on their sides and mount the amp. The seats fold down for access and there are tie down luggs factory in the same area.

Well that's it in concept. Any comments or pointers are appreciated. Soapbox

Processor: either Audio control LC6i or 3sixty (I'm trying to cut corners here and find an e-bay steel)

I feel you on the shared vehicle. Being a family man myself, i have been there, done that.

I would say it looks as if you have a nice list,

to start with, i would do all of your electrical and sounddeadening, do it slow and right.

as for those who missed out , he is short on pics just yet, they are on the to-do list though!

do work now!!!

lol

brother, loving all the pics.......

nice direction

[viper167 1]

very nice ! cant wait till my sa8's come in!

[Aaron Clinton 2,372]

Looks good.

[kirill007 52]

I would love to see the double 8's Tline, but i don't think you will get 145dB with them in a Tline.

To what is the Tline "tuned"?

But Tlines are a lot of fun, they sound loud and really clean and real tight bass.

Edited January 28, 2010 by kirill007

[Soapbox 7]

The t-line is tuned to 30. 2-8's @ 2 ohm load SAZ 1500 = approx 945 watts or 145 over rms.

I purchased the following:

1 set of dual one of quad RCA's Knu Krystal

1 3/4 grommet for the firewall

150 ft of 16 gauge knu speaker wire

100 ft of remote power wire from knu as well.

Stock positive has a 80 amp fuse on it stock

Stinger 80 amp fuse block for replacement of stock.

4 x-scorpion battery terminals

2 of the big 3 are completed I did all of the grounds in 0 gauge

I got another 8" so I don't know what I'll end up running. Most likely 3 8's; however, with the recommended enclosure sizing from .6 to 1 cube I still have the option to just cut another hole in most of my designs leaving .75 cubes each .

I have began shopping for a used 4 channel amp and think I found a zed designed crossfire 4x100 for 50 dollars.

Why is it that in system installs there always seem to be 3 more things to purchase?

[porkchop 304]

i need only three things for my system, lol, too wierd.

* radiator for truck

* heater core for truck

* rear drums for truck

FAIL!!!

lmao

[Soapbox 7]

Here's the 3rd box.

T-line needs closed up, sub holes and port hole. Not bad for 2 hrs work though.

I ran the float charger on the 2 yellow tops today too.

[emh9009 199]

tuned in. i like those cars, and love the subs

[Soapbox 7]

I added 45's to all the inside corrners on the t-line.

Purchased the following:

Krystal Kable 2 Channel 6M Twisted Pair RCA Cable

Krystal Kable 4 Channel 6M Twisted Pair RCA Cable

Krystal Kable MP3/iPod RCA Adapter

Krystal Kable 2 Channel 1/2M Twisted Pair RCA Cable

Kolossus Kable 18 Gauge Blue Primary / Remote Wire 200'

Klear Kable Blue 16 Gauge Speaker Wire 100'

Audio Control LC6i

Jasper circle jigs 200 & 400

Sennheiser eH 150 Dynamic Closed Circumaural Headphones

2 D rings to make sure things don't move around.

Installed 1 of 2 yellow top's

Need the following items:

4 channel amp

Second Skin

I'm realy torn what to get with the remaining 200 dollars. Deaden the car or get an amp. I like the SAX 50 but it would take all of the money or I could get the deadner and always upgrade the amp later.

[jcarter1885 995]

If the amp is what you need now then go for the amp if it fits your application and goals since it is for a good price. If deadening is a main concern then go that route, Im waiting till it gets warmer to purchase my deadener so it will be easier to apply. Its gonna come down to a compromise or coin toss.

I have a old school crunch zed made 200 I could use for now or I can pick up a used one easy as pie. It would be nice go deaden the car since I'll have the car s part. It's been has been avg above 60 here in California.

[ryan s 12]

For a 30Hz "tune," wouldn't the T-Line need to be like 10 feet long? I only have a passing knowledge of them and I don't know what your measurements are. Just curious.

Man...so many boxes you've got going on I like it.

Oh one more thing...definitely use the Zed! If you already have it...pop it in

[97T5WAGON 4]

nice work like all the boxes keep it up

[Soapbox 7]

I've been in the holding pattern for some time now. Progress has been SLOW. Anyway. All 3 of the boxes I've made sound good; however, I don't like how much real estate they've taken up. With the t-line and the kerfed port I didn't end up with any room for the amps or batteries. A word for the wise. Draw out available space and them portion out sections for equipment. Seems I got caught in using all of my energy on box design and not total system design. Anyway since the 8's have been around for a while optimum size has show it's self to be .6 cu for each sub. Off the top of my head the newest box is 18.25 x 17.75 x 14.5 deep subs facing up in a triangle pattern with one 4" aero port running under the single sub. This box is turning out perfect in assembly no leaks just using glue and screws.

Finally got the wire ran from alt to battery. This single wire took over 3 hrs to access and install what a bugger. Only one run left to complete the big three from the battery to the back of car. While I have several sets of speakers on hand for the components and coaxial I'm not sure which ones I'll use.

Available speakers are:

6pcs. 3.5" Still water designs Mohawk series full range

5 1/4 Zapco coaxial set

6.5 Still water designs Mohawk series mid-bass set

6.5 fusion components set

Not available but considering is

crescendo audio ccx6

I'm taking recommendations if offered please.

I haven't been able to totally finish the install because there has been always a critical piece missing. Currently is the SAX 100.4. Looks like this order because of a typo

Using the audio control LC6i means it's all or nothing. It's wired to a new plug which directly plugs into the factory unit leaving oem wiring in place and running new system wires. NO t-taps here.

Since I'm still stuck in the mud I'm also considering the Sound deadning but this will set me back another month!

[klee7013 10]

Keep it up u got me waiting for more

[stocks 2]

the deadening only takes a weekend

[klee7013 10]

o ya and i am working on a build with 3 sa8s cant wait to see the final product
