Got a set of CDT COM-626 from TheUnderFighter a couple of weeks ago. Ordered a 25 sq ft roll of AT 60mil for the job, but only needed about half of it for the doors. Completely covered my trunk lid, and still had enough to do my brother's trunk lid, too. I used some closed cell tape on the stock speaker mounts, but other than that it was a very simple and (inexpensive) install. Here's a couple pics...

a lil closed cell for a nice seal....

Some 60 mil, my brother put 90% of it in, and it was his first time using any deadener. This stuff is easy to use.

And after...

The tweets are double side-taped to the sails at the moment, too big to fit in the stock locations.... but I have a plan. I'll post a pic of them when I'm finished with it, but the setup sounds a heck of a lot better than the $140 I spent on it.

It's a 2005 Malibu LS V6. And, I love them. And these are CDT's budget comps? They sound nicer than a lot of the mainstream stuff you find at the $150 level....

Looks great!! I bet they sound Fantastic as well??? I have previously installed a pair of CDT HD 6 100 Braxial 6.5,and a set of CDT CL-E61NEO 6.5 components,and am very happy with the sound given,and power taken by both sets..and have put the xovers in the upper portion of the floor boards to retreive some air, and stay cool,and away from moisture Im hoping.The Mids are Fantastic,while the Highs are crisp/yet mellow..I have been through several sets of components,and have to say,that the CDT come To top of my list along with my older set of Polk MoMo..What kind of power(Amp) you got running them atm?

Yup they sure do sound good and clean and clear. I can't wait until I have some real mids and tweets in to at least try to come close to that sound! I'm sick of my crumby Kenwood coaxials >.<

I have a an XR-4S running them right now. I did have them on my Eclipse 3640, bridged, but the amp would get unbelievably hot.... I have to say, the newer kenwood excelon sounds much better than I expected. I really didn't want to put em on a class D, but it's decent.

You don't have the new gear in?

Nice !! Very Nice..Im running my Braxials off of an old school mean Machine 99@2ohms, and the comps off of an Old school BTS 7204,and sound great..I am Happy with them so far/quite pleased:)

I've got my mids in, but only hooked them up for testing because they don't fit in my OEM speaker baffles. And I haven't ordered my tweets yet because I decided not to use the amp I ordered a couple weeks ago, and now I'm looking for another amp again. At least I have my Mmats for my sub now though. So all I have left to do is tweets, amp, 2nd sub, new enclosure. Easier said than done I guess.

yup. dont cross below 110hz on any more than 70rms per side thou. them mids dont have that much excursion.

Thanks for the advice... They're getting around 100 now. What slope? I've had them set as low as 70hz/-24db, and as high as 120/-6. If they don't like that much wattage, I may put them back on the eclipse amp. I was just trying to get a little bit more loudness....

Except for that crossover that I took a jackhammer to :P

Yea, that's why I had to step up to the Crescendo MP6 mids. I had them on about 100w per side. And just couldn't turn my volume up too high. That's my only complaint for them. Everything else is phenomenal. The mid-bass is even really good at lower volumes, just not when you bottom them out.

If you haven't had a problem at 70hz with that slope, then you're fine. You'll hear them bottom out, and just back down the volume a bit. You'll know it when you hear it, it's like a loud clap or pop. Nothing to **** your pants over, just turn it down a click or two.

Finally mounted the tweets to the sails properly. When situated directly on top of the stock tweeter locations, it looks like a natural extension of the sails. I love the way it turned out, and it was sooo easy. Used some Loctite epoxy for plastics to join the back of the tweeter mount to the sail. I love the way it looks... the pic doesn't do it justice.

So, since I had to take the door panels off anyways, I went ahead and did something I didn't know I was supposed to do a few months ago when I installed these. I placed two layers of closed cell foam tape (one layer wasn't thick enough to bridge the gap) around the CL-6. The difference that less than a 5 spot worth of foam tape made is unbelievable.

http://img407.imageshack.us/img407/654/cdtinstall4.jpg

Today I ran about 80 feet of wire from the inside of the doors to the trunk of my car for an active setup on this set. I was doubting that it would make a difference. The cl-6 woofer and tw-25 tweet are cdt's entry level gear and all... I was very, very wrong. It sounds incomparably better. There are no words to describe how amazing my front stage sounds now. No words, but plenty of goosebumps on my arms. Its phenomenal.

why the foam?

why the foam?


the issue here is not the speakers. it's extremely common.

the reason? seals.

no, not the kind that get eaten by sharks as narrated by Sigourney Weaver.

the kind of seals created with perfectly crafted mounts and foam weatherstripping.

what you need to do is recreate the factory seals. these exist in two main locations.
1. between the woofer and the metal.
2. between the woofer and teh plastic door panel grill opening.

#2 (http://www.caraudio.com/forums/usertag.php?do=list&action=hash&hash=2) is usually missed.

the door panel acts as the front baffle of the enclosure since the door metal has huge holes in it. the rear wave from the speaker combines with the front - cancelling it out.

midbass/bass is all about seals and isolating front from rear.

That is why, CAT MAN.

And thank you, keep_hope_alive.... Made an enormous difference.

:goldcup: won big with that little tip. I can't believe that 1) I didn't read/hear about this when researching for my lil install, and 2) no one brings it up when answering the eight-times-a-day noob questions about making speakers sound decent. Going active and installing that foam made my $80, used, entry-level cdt comps sound like I paid waaaaaay more than I did.

I am the only one I see on forums recommending foam seals. It is vital to keep sound out of the door panel cavity. Those cheap and easy seals provide better imaging, better midbass, and more natural midrange.

You have experienced how install effort is more important than money spent. Congrats and job well done!

I agree it looks good... If only the tweeter was painted to match... :)

I'm glad that you spoke up about it. I may have never known had you not recommended it to that noob in distress a couple of months ago.

I have. And, thank you. Means a lot, considering who's giving the kudos here.

My whole interior is a cheap-looking, grey, and blah... the black tweets (along with the h/u, hvac, and gauge cluster) are actually making it look a bit better, imo.

Sometimes it's nice seeing the speakers instead of hiding them. I think speakers are beautiful?

I used a silver hammered paint for plastics, disassembled my dash pieces, and painted the black and grey silver. I like it, but it would have been much better in a black car. You just gotta make it your own and enjoy it.

It is, and they most certainly are.

And, I do! :) I actually enjoy this hobby a lot, despite not having much money to throw at it. In fact, making a little sound like a lot more is where a lot of the joy comes from.
