I am also posting this to the Accord forums, which is why some of the content is a bit "dummied" down.
I am not a professional. I am doing this in my spare time for fun. I'm glad to answer any questions you have. Please keep the haterade to a minimum.

This is going to be my worklog for my 2008 coupe. I will be updating it regularly.

My goal is to achieve the best SQ I can without getting ridiculously expensive. I saved money by purchasing cheap amps and sub. I don't care about SPL, so I don't need a ridiculous sub setup. My interior speakers are much more important to me, which is why I spent the cash for the Polyglasses and the Pioneer HU. From my experience, the quality and care of the install is much more important than the gear used. You can make 2 grand components sound like crap if you don't install them properly.

I mostly listen to punk, dance, and hip hop, with a good amount of 80s. So I need a system that is flexible and able to reproduce those genres well. I know the car is a very imperfect listening arena, but I set out to try and emulate my studio monitors at home.

I will be updating this post/thread as I go along with my install.

Head Unit - Pioneer deh880prs
Front Stage - Focal Polyglass 165cv1
Rear Stage - Phoenix Gold RSD65
Sub - Alpine Type E 12
Amps - 1 Power Acoustik 150x4 /// 1 Power Acoustik 90x2 Bridged @ 240x1
Deadening - Raammat and Ensolite

Rear Deck -
The first thing I decided to tackle was deadening the rear of the car. Just because... not in any particular order. Took out the rear deck, and applied deadening to the underside of the plastic cover. The Raamat is designed to add mass, and stop rattles and reverberation, not to absorb sound. Ensolite is designed to absorb soundwaves, and I will be installing that later onto the rear deck.

Rear Grills + Speakers -
Usually, for SQ applications, you do not want to have a rear soundstage, as it can mess up imaging. I actually like having a bit of detail coming from the rear, and decided to keep a rear soundstage. However, you do NOT want to have too bright of a setup, since the human ear can pick up high frequencies much more directionally than the low. I did not set out to buy a comp set, as there are no locations to put the tweeters, but the Phoenix Gold RSD's were a fantastic value, and give great midbass response.

I had to decide where to mount the tweeters, and decided it'd be safest to just modify the stock grills. The grills are actually only "grills" directly over the 6.5 speaker, the rest of the grill is solid plastic, and wouldn't let any sound through. I figured if I totally messed up, I could just buy another set from the parts department. I cut a hole in them for the tweeters to be mounted to. I added two layers of speaker grill fabric over the tweeters firstly because they were too ugly to be mounted naked, and secondly to help attenuate them a bit to avoid having too bright of a rear soundstage.

Sub Box/Amp Mounting -
Since I am not concered with SPL, and require my sub to be able to reproduce a wide range of music accurately, I decided to go with a sealed box. Another huge requirement of mine is for the sub/amp mounting system to be completely modular. I designed it to be able to be removed from the car in under 30 seconds using only 1 allen wrench to loosen 2 grub screws to remove the power/ground wires from the distro bock. All other wires are able to be disconnected via plugs at the sub/amp box. This allows me to easily pull out the entire system in case I need to put something in the trunk and flip the seats down.

My sub's specs call for 1.25 cubic feet of volume. I designed the box to be closer to 1 cubic feet, and added some polyfill to make up for the lost volume. I used 1/2 inch MDF for the box's construction, and designed it to fire towards the back of the car. The face is flat, and takes up the rear space of the trunk and serve to hide all of the wires. The trunk of the coupe is much bigger than I need on an everyday basis, so I won't miss the lost space.

Here are pics of it face down while I was painting the back of the box. I used some textured paint for it. I hate carpeting boxes. Don't have the patience for it at all! You can see the mounting hole for the speaker terminal cup. The curved parts at the base are to clear the contours of the trunk.

Sub Installed -
Here is my sub installed into the box. I used just regular wood glue to attach the polyfill to the inside of the box. Ran some silicone caulking on all the joints to seal it up well. Pretty happy with the looks so far. I'll be mounting the amps and crossovers next, and wiring those up. Stay tuned.

Box complete (99%) -
Got the box all done. Mounted the amps and crossovers, and did all of the wiring. None of the screw should have penetrated into the box's cavity, but I put glue on the threads of each screw juuuuuust in case.

Here are some closeups of the crossover side. I got some tech flex for the wires, helped make them look pretty. The two bundles you see exiting are for the right and left side interior speakers. Helps to keep them organized. I decided to mount the crossovers on the box instead of in the doors because they have some adjustments on them, and I didn't want to go through the hassle of opening my door if I ever wanted to make an adjustment. I used Dean's Ultra plugs for all of the connectors. They are designed for RC car usage, but are very useful here. Each plug has a male and female end, with specific polarity, so you can't plug them in and reverse the polarity. Also, they are very sturdy and require a good bit of effort to unplug them, so I don't worry about them coming undone on accident. Lastly, they are very low loss and have a huge contact surface between the male and female plugs. Very nice indeed. Only bad thing about them is that they require soldering, which some people don't like doing. I dn't mind it at all personally. For those of you with sharp eyes, you'll see the only thing I'm missing is the ground distro block. It's in the mail!

Your install looks nice ;) I like it.

Why didn't you go with two sets of RSD's??

Thanks for the comments guys.

I know my sub is weak sauce cheapo :) I'm embarrassed of it and my amps, but gotta save the $$ where I can. It'd be easily swappable if I decide to get something else.

Didn't go with two sets of RSD's cuz that'd be forum boner x2, and thats too much boner in my car. Haha. Really, I went with the polyglasses up front cuz I like a bit of a brighter stage, and I love Focals. I had a set of Access before, and I loved them. So I got a bit of brand loyalty going on.

Ah my bad. Didn't interpret it right. This part threw me off.

I'm watching this on the DA forums as well! I can't wait till it's complete. I am going to be installing a semi-large system in my coupe as well, as soon as I can get together with bamaboy. Looks good though!!

I'm pretty sure you interpreted it right.

It means the "complete" build log, key word being "LOG"... I think "complete" means the whole system or something, not JUST a box or w/e.

Love the car, the front stage speakers, not a fan of the sub though. And what amps are you running? I can't really tell.

Used this http://www.rustoleum.com/cbgimages/products/AAStsBkGSpL.jpg

Made by rustoleum.

I didn't prep using anything. Stuck to it perfectly fine. The only thing I might do in the future is use some black primer, just to avoid having to do so many coats to hide the wood showing through.

Totally with you on your opinion of the sub. I'm pretty ashamed of it. Haha. But it gets the job done for me. I don't push it hard at all, and I rely on the good midbass performance of my front stage more than the sub. It definitely is on my list of upgrades that I should make in the future though. I have enough power coming from my sub amp to power something better later on.

I'm just running some power acoustik amps. Cheap, and they work fine. I know they are totally overrated @ their quoted wattage, but even with this in mind, they're still a good deal. Some people might be able to tell a difference in sound between an expensive amp, and a cheap one, but that is definitely not me (power levels being equal of course). Maybe I need to upgrade my ears. 1 is a gothic, 1 is a power series. According to their tech dept, they're identical internally. I only got a power series since they were out of stock of the gothics.

Driver Teaser -
Here's a little teaser. I was very impressed with the quality of the RSD's for the price. I bench tested them outside of an enclosure against the polyglasses. The polyglasses had a a bright and lively sound, also sounded a bit fuller, and were definitely more efficient. The RSD's definitely held their own though, and did NOT sound like 80 dollar speakers at all. Keep in mind this was totally bench testing, not mounted at all, so this could totally change once I get them installed.

Goal for tomorrow is to install the rears, deaden the deck, and put the trim back on.

Thanks for reading.

Yo, man. Nice build.

Screw the other people. This is the right place!


x1 for getting the wording changed from "Completed Build Logs" to just "Build Logs"

Rear Deck Complete/MDF Ringage -
Here is the rear deck put back together with my modified speaker grills. The tweeter's locations look very clean.

http://i26.tinypic.com/2vvl1tc.jpg

I cut some MDF rings also for my rear speaker. I decided to go with 2 thin rings for each speaker, and sandwich circles of deadener between each, making a total of 2 layers from deadener between the speaker and the deck. I would have gone with thicker MDF, but it would have gotten too tall and would have hit the grill. A lot of experts use non-hardening clay between the rings and the metal, but I worry about the California heat a lot and don't want my paranoid mind to wonder if my rear deck is melting or not.

I used a handy dremel circle jig that I picked up, and it cut the holes very clean as long as I went slow. Much easier to handle than my big router when it comes to cutting holes. When I got impatient, the cuts got a little bumpy, but still 100% acceptable for simple speaker rings.

Trunk Liner -
In my process of deadening the trunk, I decided to add some closed cell foam (Ensolite) to the back of the trunk liner. I used some spray adhesive and did it all in one piece. I tried my best to match all of the contours of the trunk liner, and think it came out pretty good.

Awesome job mang! Not a big fan of the amps, but as long as it does that trick for you, then that is all that matters. Love the attention to detail of the entire install. I may pick up a set of those RSD's if I don't like my Alpine SPX'S. They are a nice set, but very mellow IMO.

I will have pics up next week of my install, well mostly my sound deadening install as I had my system in there and had to take it out and reinstall it. Deadening *****, as my hands look like I got in a fight with Edward Siccsorhands.

Good luck on the rest and will deffinetly check back.

Door Trim Panel Deadening -
Even with the stock speakers, when played at anything past a medium volume level, I noticed that the door trim panel and armrest area would vibrate like crazy. I decided to do some deadening action on it. I built up a lot of layers around the speaker grill, just took whatever scrap I had left, and piled it on.
