1st build log ever. 2001 Nissan Sentra GXE

[Original wis]

Update:

Finished the interior. Saving up for new subwoofers and amps. Going with 4 DC Audio level 4 10's in 4.8 cubes on a Salt 6k. With 610 amps of electrical I figured it would be ok. Definitely models well. The Adire Audio Brahma subs do as well with the same exact enclosure and wattage.



More updates once I have amps.

Quick update:

Finally found all of the missing brackets needed to mount the head unit and the Clarion EQ. Ignore the Dual mechless it is definitely not a part of the final build it's just a placeholder for the eventual mechless that I plan on purchasing.

Plus the body kit finally came in. Took me several months to find the pieces because they're not being manufactured anymore. I like the fit though. The plan is to paint the mesh gold and the car black so it matches the interior. I purchased a roll of what looks like metal fencing and the plan is to cut and mount it diagonally to match the diamond shape. It'll look nice in the bottom cutouts that are open.

Still saving for the subwoofers. Probably going to end up getting a Helix dsp since it seems to be a crime against manhood to purchase anything less. So that means at least another 6 months of saving and finishing everything else piecemeal during the wait.

Update:

I fabricated some fabric glass kick panels. I've never done anything like that before ever in life so I'm going to show you some pictures of how it went.


So I took some pods, glued them to the kick panels, then covered them in 3 dollar Walmart polyester. I then proceeded to paint them with waaaaaaay too much fiberglass because rookies make mistakes.


This is day two of me trying to sand down way too much fiberglass and not being successful.


Day 3 I came up with the idea of buying primer and I covered the entire thing in like 10 coats. Took 2 days to dry. Days 5-6 I sanded everything until it was smooth. I used 60, 80, 220, 400, 600, and 1000 grit. That seemed to work.


10 coats of paint and 10 coats of clear enamel later, I was ready to do the cutouts.


Final form.

What do you think? Any advice on what I could've done better?

Next update will hopefully be the subwoofer box build.

Next time, use body filler and spot putty to smooth em out. While they look a little rough, kick panels are not an "in your face" item. As long as they are rigid, should work

For the $800 that I'm going to spend on cells I could get a Taramps smart 3 and 4 12" CT Sounds 800 RMS Ozone subwoofer s. And it'll run on my current electrical, 250 alt and 100 ah AGM. Be ridiculously loud with just that in an 01 Sentra.

I've been a year without music and right now that's looking really good. I might have to save up and do the bigger system later. I can add a Dsp later on as well as electrical, and subwoofer upgrades.

Really looking like it's worth it just to have music.

Update:

Found DC Audio level 1 12s for $89 each. I have 4.
Found a Taramps Bass 1200 for $119.
My brother's sending me a Dayton DSP!

I'm getting so close to the finished product... Looking for a box builder and amps to power the mids and highs.

This is a good one for a chuckle. This was my original build before some of you awesome people talked sense into me.

My eternal thanks to you all. You were so patient with teaching me while talking me down from the ledge. I would've wasted so much money.

But thanks to you all, I learned and applied. Thank you. You all rock.

So I've done a lot of research and have learned a lot during this process but before I press the buy button I wanted to see if anyone can see anything wrong with this build.

300 amp fuses in the following places:

200 amp fuse from busbars to amp

Here's my mid/voice/highs or whatever build.

4 Power Acoustics NB4 1.5 in tweeters. Yeah I know, I never thought either but they sound fantastic.

Taramp's TS 400 X 4 at 4ohms, 60 watts per channel to match tweeters.

4 Rockford Fosgate Punch 6175 3 way coaxials.

Taramps 440 X 4 at 4 ohms, 69 watts per channel.

My thoughts are that the Fosgate coaxials will fill the mid bass and voice, leaving the Power Acoustics to overlap and fill in the highs. I know comps are the thing nowadays but I think these should serve the same purpose

I have a Clarion 7 band knob 1/2 din EQ so I can tune while in traffic on the fly.

I'm getting a DSP as well but I don't see a reason to pay like 800 for one 10 channel when Taramps 6 channel is 129. Even Dayton Audio has an 8 channel for 159. I'm just not familiar with the brand.

I modeled the box response for my dimensions. Here's the results including cabin gain.





Anyone see anything that needs addressing?

Update:

Amps came in. Here's the amp rack:



Any feedback is appreciated.

[Original wis]

Amp rack installed.

Tomorrow wiring DSP and doors. Wiring speakers to amps. Connecting power and ground to amp rack.

We're getting closer.
