FULL SWS-8 sub and amp install, 34 pictures, step by step
I gathered a ton of information from this site about how to upgrade the stock subwoofers and amplifier. From this information I have created a full, step by step tutorial that will guide you through the entire process. It is 27 pages long and has 34 pictures included....
Check out the PDF below the pictures for the tutorial. Here are some teaser pictures. https://www.dropbox.com/s/4md1oz9pvt...20PDF.pdf?dl=0 Let me know what you think or if you have any questions.... Note to mods: The place I have it hosted is pretty reliable, but... I wanted to upload this to the forums so the PDF would always be available, but the upload kept failing. If you could somehow get it on to your servers that would be great, thanks. EDIT: if your having trouble viewing the PDF right click the link and go to save as. EDIT2: as several have suggested I have moved the fuse to the other side of the car, right after the battery, I updated the PDF to show its new location... EDIT3: 2017/02/07 - Fixed download link.

Excellent write-up and nice PDF. You clearly took a lot of time to prepare that. Overall, you did a very clean, nice job, but I wanted to make one comment. It looks like you put your main power fuse across the car from the battery, near the amp. Please consider moving it to the side with the battery. That fuse is not to protect the amp, it's to protect the wire and should be as close to the battery terminal as possible. If that wire were to rub through where you ran it through the metal channel, you would have a huge, 10-gauge short with no fuse in it that could easily start a fire in your car.
Again, overall I think you did an excellent job and thanks for contributing. |

Not trying to push and you do whatever you're comfortable with. I just don't want to see anybody lose their car when it could be prevented. I worked in mobile electronics for quite a few years when I was younger, even owned my own shop for a while. I've seen way too many burned up cars because of a shorted power cable. |

Great work on the PDF! I really like your ideas on sealing up the small opening in the OEM sub box. I was going to use MDF but the clear look is really nice.
On a side note, I've installed a few systems too and ideally you want to keep the fuse literally a few inches from the positive battery terminal. I know it's extremely unlikely that there will ever be an issue but knocking on wood as I write this, if there were ever a vehicle impact or something that could damage that power line, there would be 4-5 feet of live power wire that could cause a major fire or with a prolonged short circuit cause the battery to explode.

Another thing I have noticed after the install is how sloppy and loose the stock subs were, it seems now that they were just making noise in the general frequency. These SWS's hit hard and are very very crisp. The car does not at all sound like a riced out civic, it sounds like a rich silky smooth BMW sound system should, it puts a smile on my face.. really. I would actually venture to say that this is now the best sounding system I have ever encountered in a car, and I've been in alot of cars... Note: Just to clear this up, I am not an employee of earthquake, I am just blown away by the quality of their products and outcome of this install and wanted to share the wealth with the rest of e90post.... enjoy!

Those subs will seriously get overpowered by that amplifier so be careful. The subs are excellent but you don't want exceed their rated specs. Tom Nousaine discovered that when he reviewed the subs. 150 watts RMS each is all they need. Your amp is capable of pushing over 3x that power to each sub so be careful.

Awesome writeup OP, thanks very much for the contribution!
Does anybody know if there are other subs that fit in the stock location. I know there is a Morel but it is hellishly expensive. Another question revolves around the vented enclosure specifications of the OEM enclosure. What is the volume of the box and what length and diameter is the port? Is the Earthquake well suited for this particular enclosure? What about sealing the enclusure off and turning it into a sealed box? |
