Just thought id share a photo of a recent fibreglassed sub enclosure i had custom made for my clk cabrio.. i wanted to go for the clean factory look and still have my boot space...
Has anyone here have any boot install pics of their clk coupes and cabs ?
id love to see other ideas..

That looks very nice and clean, Good Job.

It looks clean. Question, how is the sound/volume compared to the stock woofer that ports directly into the cab? From the pics, I presume this is a sealed sub enclosure.

Very clean!

I wouldn't know as my car didn't come with the Harmon pardon sound system.. Yes It's a sealed box with the new 10 inch alpine type R slimline sub.. To be honest it could use a bit more bass.. I think might be a faulty subwoofer as I had the installer tune it down as it was underloading during certain parts of songs... Could be a faulty sub so was gonna get it either replaced or have it returned and get the new Memphis slimline subs..

I used to have a big standard size 12 inch alpine type r subwoofer and it was just in a big sealed box ( I'll include pics later) and it used to shake the hell out of my rear window as it wasn't a fixed roof so it would rattle in between te window and the cars body

It (from the pics) looks like a very small volume (area) box, it's going to be tough to get much deep/loud bass out of it with the 10. I had a pair of 10's in a sealed box in a competition car that could, if called upon, shake the paint loose - they were not small volume box subs like the slim designs of today call for.

Was the box built to volume spec or built to fit the car or both? Is that sub design able to be ported? If so, you'll pick up some volume and lower notes.

Np55

Yeah not sure about being built to exact volume spec but the installer was sure that the box was enough and it was a shallow mount sub only requiring 3.25 inch mounting depth and less than 10L for volume .. Yes that sub could be ported but the box is already built now.. I might try another sub also the installer had another idea to put a flat panel at the front of the sub so that it can load off the panel and bounce back into the cabin. I remember facing the sub towards the rear of the car and it had slightly more bass

Kevwood

That was going to be my next suggestion - loading. I had a single 12 loaded years ago, worked pretty darn well (nothing dramatic though), instead of using wood I used a piece of 5/8" plexiglas, looked fantastic.

Your always going to struggle when you're using a sealed sub in a convertible but it sounds like you've got some good ideas on how to move forward. Good luck!

D*** It! I'm goin gto have to re-do mine now. That looks way cleaner.

Kevwood

Aren't you still working on a badass setup? Been a while but I remember seeing your pics of routered amp rack designs...?

Jamesbbh

For right now I just hollowed a spot out of the foam in the spare tire well and hid the amp in there but I think I might actually use the cover I made whenever I re-do everything. I haven't really been happy with this box since I finished it. It just looks amateur to me. I think the second time around I'll be a lot more efficient with the fiberglass.

Jamesbbh

If you don't mind me asking, what did you pay for this box?

Np55

I paid $800 AUD. Note that things here in Australia are more expensive that in America.. You guys would freak out at the prices here.. Are you happy with your bass from your sub? I'm not filly happy with the bass output with my alpine one.. Fitment wise it's perfect and clean however could use more bass.. Someone recommended me the Memphis slimline subwoofer.. Unless my alpine sub is faulty as it was underloading during the low fast beats of songs.. It had to be tuned down however these subs are supposed to hammer as they say..

slim line subs dont seem to have the same power as a full sub. i considered a slim line at first but the audio store convinced me to buy a full sized sub. my only regret is the size. i like the amount of "bump" that it produces. but the fact that it takes up more than half my trunk bothers me a bit.

yes i know i still need to take a pic. but the box makes it hideous compared all your custom enclosures. lol

Jamesbbh

I really wasn't going for TOO much bass as I still have the factory HK speakers everywhere else and didn't want it drowned out so it's plenty of bass for me so far. When I re-do it (which will probably be the next couple weeks) I might get some more airspace somehow, port it, and de-tune the amp down to what I want. Yea you might want to make sure it's wired for the correct Ohms and whatnot between the sub and amp, from what I hear the alpine R's are a good speaker. You can look up easy wiring diagrams and look at the amp/voice coils on the speaker to make sure they have it wired correctly.

Looks sicks but it there a way to replace the stock harmon karmon subwoofer and still have it ported through the same stock place in the rear of a carbiolet?

bheng

^ look up stereo upgrade from member v12. and good luck cuz it didnt look easy

ahmadk

looks clean
and james...your setup gives you some room so you can put some stuff on the woofer

VividRacing

Both installs that are pictured look great, but I do agree that the 1st one looks more OEM. I'm not a fan of loading or bandpass enclosures, personally.

City Rat

This looks great! I knew that there was another way to skin this cat! I just replaced the Command head unit yesterday and among other things the installer suggested a sound ordance compct powered sub to go under the seat. Wouldn't fit but I was so desparate for some bass to go with stock Bose speakers I had him put it in the footwell behind the driver's eat while I searched for another solution. This is the best placement solution thus far.
