Honda Civic Coupe 08 2x2k???

Recommended Posts

Hello and welcome to my daily headaches! I'll start this build log off with my past setup, my current, and finally update throughout December as I work on probably the furthest this little Civic will let me go.

My instagram: https://www.instagram.com/joshdashef1/

 

The Past Build:

Head unit: Pioneer 80 PRS 

Mono Amp: Rockford Fosgate Prime 750.1

Subwoofers: Rockford Fosgate P3D4 12" (two)

Kicker 4 gauge amp kit OFC

Stock Electrical (alternator included)

Did do the big three sometime between here and current build

Prefab Box: Q-Power Box (Dual 12s)

Tips: Tesa taping RCA's, Marking RCA's Low/Mid/High or similar,

tumblr_p86k78j9471xsodn1o6_400.jpg

Big Three with loom. Wire was Sky High 1/0 OFC with some 1/2" loom I believe. Old military style terminals (DO NOT USE THESE) they cracked my battery eventually.

Work to get to current build: (a lot from 2018)

 

Day 1: Stripper Time

tumblr_p8c96dBT3k1xsodn1o2_r1_540.jpg

Looming RCAs (Rockford 20ft or 16ft twisted with some Tesa Tape):

My tip for those doing anything similar is to utilize a loose zip tie as a tool to control the unwrapped RCA cables

tumblr_p8ccgd0oNq1xsodn1o1_250.jpg

tumblr_p8ccgd0oNq1xsodn1o4_540.jpgtumblr_p8ccgd0oNq1xsodn1o2_1280.jpg

I also recommend marking your RCAs so you can distinguish between them on the other side!!

tumblr_p8cctu8P021xsodn1o1_540.jpgtumblr_p8cctu8P021xsodn1o10_540.jpg

Sky high dual fuse holder (doesn't fit larger gauge wire easily...

tumblr_p8civn2Qnq1xsodn1o7_540.jpg

Bass Knob Mounted by driver side knees. 

tumblr_p8cj3kDw8X1xsodn1o1_540.jpg

Sound Deadening, going for some resistance to rattles here:

tumblr_p8cjoyuJuc1xsodn1o1_540.jpg

Dual run of Sky High 1/0 OFC. Flexible to a point wire, but very over-sized so be careful with what termination you buy!

tumblr_p8jlo2xPtW1xsodn1o2_540.jpg

Best damn tool I have ever bought for getting through a firewall.... Unibit buy it. (comes in different sizes!)

Also DD-1, can be found here: 

If you plan on setting gains, get one of these (or an oscilloscope)

tumblr_p8jlo2xPtW1xsodn1o1_540.jpg

Drilled basically where the clutch would be if I had standard trans. Added rubber grommets off amazon, use a little petroleum jelly to help coax the wire through if you have trouble.

tumblr_p8ldyewhim1xsodn1o4_540.jpg

Planning Wire run to rear: Loomed in same 1/2" loom and some zip ties/tesa tape when needed.

tumblr_p8ldyewhim1xsodn1o7_540.jpg

Crossing into middle of car under drivers feet. Yes I can feel the bump, but it is no where close to where I rest my foot daily driving. Also ran from near center console to driver side rear seats, eventually into trunk on driver side.

The switch to SMD fuse holders. I love these things. Absolutely worth spending the extra cash for each of these!

Also the dealer I bought them off of, AudioFanaticz, threw in some goodies!

tumblr_p8uf02VZP91xsodn1o1_540.jpg

Great Fuse holders, but bad mounting on my part... Definitely will address this issue this month!

tumblr_p8wd1z8iVg1xsodn1o1_540.jpg

Rear Fuses for reserve battery

tumblr_p8wd1z8iVg1xsodn1o4_540.jpg

Mounted to side wall, then insulated with some tape just in case.

Grounds color coded with tesa tape. Used a DMM for finding a suitable grounding location. This spot surprisingly had low resistance!

Building my first ever box:

My designs came from JeepandBass: https://www.jeepandbass.com/box-designs

If you are just getting into the game then I recommend having someone else design your box. Then design your second box like I am doing!

Bought two sheets of MDF

tumblr_p93zamlfdS1xsodn1o1_400.jpg

Portable table saw for long cuts

tumblr_p93z76r80N1xsodn1o3_400.jpg

Wear protection! No jokes this stuff is not good for your lungs or eyes, so gear up and clean up.

tumblr_p93z76r80N1xsodn1o10_400.jpg

All cut out

tumblr_p93zamlfdS1xsodn1o2_400.jpg

My Hardware: Brad Nails to assist with holding pieces for follow up coarse threaded screws

 

tumblr_p93z76r80N1xsodn1o8_400.jpgtumblr_p93z76r80N1xsodn1o7_400.jpg

1" screws and brads | 45s

1 1/4" screws and 1 1/4" brads | Baffles connection between layers

1 5/8" screws and 1 1/4" brads | Most joints for the box excluding the connection between the baffles and sides/port

2 1/2" screws and 2" brads | Baffles connection to sides walls/port walls

Tip for cutting circles in a MDF!

Screw into a scrap length of wood the size of your subwoofer diameter plus some. Then mark out your cutout diameter by using a ruler to mark where your next screw will go. After that you now have a template you can use to score into any wood for a speaker of the same cutout diameter!

After doing this I glued on the second layer behind each side and screwed it in to let dry over night.

tumblr_p95q0uOdIF1xsodn1o2_540.jpgtumblr_p95q0uOdIF1xsodn1o3_540.jpg

Put together the sides of the box and back wall

tumblr_p95q0uOdIF1xsodn1o1_540.jpg

After the baffles glue had dried (23 hours). Cut out the scored circle with a jig saw (router would be much nicer and easier, but more expensive for entry level)

tumblr_p97tcrDNtL1xsodn1o1_540.jpg

Smooth with sandpaper

tumblr_p97tcrDNtL1xsodn1o3_400.jpgtumblr_p97tcrDNtL1xsodn1o2_400.jpg

Test fit

tumblr_p97tcrDNtL1xsodn1o4_540.jpg

Planning:

tumblr_p97tneNiwt1xsodn1o3_400.jpgtumblr_p97tneNiwt1xsodn1o1_400.jpg

tumblr_p97tneNiwt1xsodn1o2_540.jpg

Some sanding on inner port wall to knock off hard edges

tumblr_p97tneNiwt1xsodn1o5_400.jpgtumblr_p97tneNiwt1xsodn1o6_400.jpgtumblr_p97tneNiwt1xsodn1o7_400.jpg

Planning out screw placement and panel placement on top piece

tumblr_p99q9cSivz1xsodn1o9_r1_540.jpg

 Notice the overhanging baffles. Yeah someone fucked up! I decided to leave them since I was dying to hear it, but could have just as easily sanded them down.

tumblr_p99q9cSivz1xsodn1o4_540.jpgtumblr_p99q9cSivz1xsodn1o5_540.jpg

Final Product:

tumblr_p99qdtM1O41xsodn1o5_540.jpgtumblr_p99qdtM1O41xsodn1o4_540.jpg

tumblr_p99qdtM1O41xsodn1o3_400.jpgtumblr_p99qdtM1O41xsodn1o2_400.jpgtumblr_p99qdtM1O41xsodn1o1_540.jpg

Now thats a big ass box... This required a lot of coaxing to fit, but after turning it then putting it in... she fit.

Work to get to current build: (a lot from 2018)3

Start on amp rack and battery mount with scrap MDF and some cardboard cut to fit on driver side little cubby.

tumblr_p9daibpNKe1xsodn1o3_540.jpgtumblr_p9daibpNKe1xsodn1o4_540.jpg

Hooked up battery fuse holder to main runs. Hate myself for this fuse holder placement without reinforcement! 

tumblr_p9daibpNKe1xsodn1o6_540.jpg

My little MDF box for a D3400 and some shiny aluminum bussing. Enclosure was glued then has two screws for removing the battery. 

tumblr_p9gre1k9II1xsodn1o4_400.jpgtumblr_p9gre1k9II1xsodn1o5_400.jpg

Planning power runs for amps

tumblr_p9gre1k9II1xsodn1o1_540.jpg

Another idea that works but could stand a redesign. Horizontal fuse mount. At first it had tons of play in it but after adding the top piece that held it upright, it mostly stays as is. 

tumblr_p9gre1k9II1xsodn1o2_400.jpgtumblr_p9gre1k9II1xsodn1o3_400.jpg

Wiring P3D4 12s. 10 gauge sky high wire

tumblr_p9gre1k9II1xsodn1o7_r1_540.jpg

Loved these grills that Rockford has

tumblr_p9gre1k9II1xsodn1o9_r1_540.jpgtumblr_p9gre1k9II1xsodn1o6_r1_540.jpg

tumblr_p9iwcmpwG41xsodn1o1_540.jpg

RCAs ran to rear. Ended up with a lot of excess cabling. 

tumblr_p9iwcmpwG41xsodn1o4_400.jpgtumblr_p9iwcmpwG41xsodn1o3_400.jpg

Finally. The moment I had been looking forward to for days after days of work

tumblr_p9kpvr22ai1xsodn1o3_540.jpg

tumblr_p9kpvr22ai1xsodn1o1_540.jpg

Electrical tape for the sides that are closest to each other at the amp terminals. Both + and -

tumblr_p9kpvr22ai1xsodn1o4_400.jpg

The setup v1

tumblr_p9kpvr22ai1xsodn1o2_540.jpg

While tuning and testing this I ran into a voltage problem, low 13s. I decided to fix it

Mechman 240A Alternator in Blue!

tumblr_p9mkb5Qg281xsodn1o3_400.jpg

Heres a side to side for laughs

tumblr_p9mkb5Qg281xsodn1o9_540.jpg

Old versus new. 1/0 ran from alternator + to battery (fused), and alternator - to battery negative. Whoop Whoop!

tumblr_p9mkb5Qg281xsodn1o8_400.jpgtumblr_p9mkb5Qg281xsodn1o5_400.jpg

Installed 4 channel, RF P600x4. Front speakers not hooked up yet.

tumblr_p9okg4jg3y1xsodn1o2_540.jpg

Connecting up some LED's off amazon by soldering on some wire and terminal for my Blue Seas System Fusing: https://www.amazon.com/Blue-Sea-Systems-Blade-Block/dp/B001P6FTHC/ref=asc_df_B001P6FTHC/?tag=hyprod-20&linkCode=df0&hvadid=312128389336&hvpos=1o1&hvnetw=g&hvrand=16344823841222530695&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9011457&hvtargid=pla-383472770805&psc=1

Work to get to current build: (a lot from 2018)4

Adding some Dynamat to the doors and behind speakers, thinking of comparing this stuff to some SecondSkin deadener on the rebuild.

tumblr_p9vysu5Tnu1xsodn1o2_540.jpgtumblr_p9vysu5Tnu1xsodn1o9_540.jpg

Trying to stop some plastic rattle with Tesa Tape

tumblr_p9vysu5Tnu1xsodn1o1_540.jpg

Ran speaker wire to rear

 

tumblr_p9vysu5Tnu1xsodn1o7_400.jpg

Old Tweeter mount, Florida = melted glue whoops. Should have used some JB weld instead...

tumblr_p9xoo7zile1xsodn1o1_400.jpgtumblr_p9xoo7zile1xsodn1o3_400.jpg

 

 

tumblr_p9xoo7zile1xsodn1o2_540.jpg

Noticed the plastic rings on the inside of the panel were not able to be seated all the way back because of the adapter mount. Decided to cut it shorter and apply some foam tape.

tumblr_pauz44eqjt1xsodn1o5_250.jpgtumblr_pauz44eqjt1xsodn1o7_250.jpg

Applying some SS damp rope. I definitely want to redo this mounting bracket with some ABS plastic and some deadener.

Fixing a side panel with zip ties and a drill

tumblr_pd29iuo4vQ1xsodn1o1_540.jpgtumblr_pd29iuo4vQ1xsodn1o3_540.jpg

Went back and sanded alternator connection

tumblr_pd29iuo4vQ1xsodn1o4_540.jpgtumblr_pd29iuo4vQ1xsodn1o2_540.jpg

Replaced cracked wally world battery with XS D5100R

tumblr_pdxmg0OCb81xsodn1o6_540.jpg

Switch to SA 12s from P3s

tumblr_polf4ouZ4E1vjgzep_1280.jpgtumblr_polf4oWFK91vjgzep_1280.jpg

Yes I never finished this box, but I never planned on keeping it. I think if I take it out i'll sand down the imperfections, and wrap in some carpet. Might end up putting it in my friends car too :dancing:

The Rebuild 2019/2020

Finally have reached the point I want to redesign everything. I'll be tearing out everything in the trunk and redesigning the box for a single 15, two DC 2ks, same 4 channel amp, and better electrical. So far I have ordered a 1000 Farad XS power superbank, but I think I will end up replacing the D3400 with a XP 3000 or two. 

Wanna drop a plug to the https://store.soundsolutionsaudio.com/ for their excellent customer service and extended Black Friday deal on both my second DC 2k and XS SB1000-31. Thanks Guys!

SP4 v2+ 15" Dual 1 ohm | 7" Gloss Carbon (Ice Blue) | 4 spiders | Cooling | Hybrid Leads |

Packaging is 11/10, also heavy AF

Thanks for sharing.

Ive been looking at the SP4 as well. What made you choose that over the BTL?

Honestly, the hugely positive reviews of it. I’m sure the BTL is just as good but if I’m remembering right each serves a purpose. I decided the v2+ after discussing it with some other users seeing as it offers higher motor force (Better for ported enclosures). 
 

I planned on getting a driver orientated towards daily driving with great output 30-40hz. I am still juggling whether to go for a tuning of 28 or 30-32. SP4 fit the bill. 
 

4 inch coil is less efficient perhaps but I think extra thermal capacity is a nice trade off. My commutes an hour to and an hour back so plenty of time to get her moving

Sounds good to me. I read somewhere that the SP4 is a bit more musical than the BTL as well.

XS SuperBank came in from SSA store today, look at the size compared to that 18650! Just waiting for my 2k to be shipped now.

- New electrical will be much of the same; Mechman 240a / dual 1/0 runs / D5100R underhood / SB1000-31 / and either a D3400 or I'll switch over to XP3000 or two.
