Ok, so I have a Kenwood 3011 12" sub...I got the recommended dimensions from Kenwood for a sealed enclosure. My question is can I change those slightly (make it more wide than deep, assuming the speaker has enough mounting depth to fit) while keeping the same volume, and it maintain the sound quality?

Sure can as long as the baffle panel holding the woofer is large enough to fit the sub, you can do it any shape desired, but maintain the air space +/- 5% of recommendations.

PS Are ya able/willing to help Sondy_25 with a little coaching? I'd like some assistance on that one.
zanilth on 02/7/2009 15:48:57
I wouldn't have an issue with helping Sondy out, but honestly I think it would be a case of beating a dead horse... I almost refuse to believe he has a vehicle without any kind of wiring harness, although I have seen some less than par vehicles before.

Yes, I see the same thing, but we try to take it slow with guys that are really new. Heck, we were all newbies at one point and as we advance, it gets harder to have patience with a total newb.
Indeed, this will be interesting, but also a test of communication skills, thinking on the fly and working as a small team works well if we don't lose perspective.
Glad you're up for the challenge and I hand-picked you for good reason,

Thanks for the confidence :)
I think he might be from the Phillipines instead of Australia... I am just hoping he has some sort of wiring or something in his vehicle already. Otherwise, it'll definitely be fun walking him through fresh wiring and everything. I've never done anything that complex, so I'd appreciate if you can correct anything I may say incorrect. Thanks :)

You may be right on the Phillipines call. Where do you hail from Zan? I'm from the western burbs of Detroit.
Expect this to be a challenge so we don't set the bar too high in the beginning. I appreciate your willingness to get aboard and yes, we'll noodle it all out together.
We need fresh hands on the forum too. Some of the Golds get tied up and there's a lot that have not been here in some time. That makes it a good opportunity for others who have the interest to fill in and let their skills develop. That's why I asked for your help. ;-)
Swez
PS Now, if Sonde would just come back and answer a few more questions, we can move forward.

I'm from Louisiana, around Pineville/Alexandria area.
Yeah, I figure if it progresses any much further it will definitely be an interesting situation as far as getting everything installed. One thing I'm not quite sure about is how he would set up a remote wire for the CD player....I would say just run off of an already made fuse (like most people do for amps) but then again I would want to make a slot for a fuse for the radio itself...thats if I were doing it lol.
I figure working step by step should simplify things a bit, although it will be a considerably lengthy process....But I'm game lol. Plus can learn some stuff from you during the process :)
swez on 02/7/2009 20:58:24
Yep, we'll have to deal with many unknown variables if this fellow is intent on doing a good job. The hard part is the gear he has mentioned so far. We have so little info to go on until he comes back and fills in the gaps.
Much of the gear mentioned is not available in the US market. Getting tech manuals and product details will be a snag as will be speaker locations available.
If push comes to shove, he can always use prefab enclosures for the front and rear speakers. (Fabricated enclosures) It's just a matter of mounting them well, getting HU and amps connected and than add his sub.
From what I have gathered so far, the amps are both 4 channel Pioneers that are sold in AU and the Phillpines. Same for the HU. The basics are still the same, but interface/compatability issues may pop up later. There are ways to bridge most of these gaps, but it will be slow going.

zanilth on 02/7/2009 22:03:49
Yeah, thats basically what I got as well. If you notice, the last thing I asked him was to verify there was a place to mount the deck and speakers lol. One concern I have is if this isn't a factory built vehicle, there are a few things that might be different, such as the electrical system. So without a considerable amount of information more (which I don't really forsee us getting) we will almost have to make asumptions that may or may not be correct.

Well, Sonde mentioned the dash board is from a Honda Civic. That makes things a little easier as most Civics have a 2 din opening. If his vehicle has the corresponding wiring harnesses, it will be easier. If not, a custom harness he will fabricate on his own, can be done with our guidance.
My concern is the correct interface cable for his Pioneer 12 CD changer. If his present HU has that feature, the rest will be easy in that area. If not, his options are slim and none.
More later as Sonde did reply again,

zanilth on 02/8/2009 09:35:01
Hrm.
I have installed a deck unit in a honda accord, but there is no way of telling what year model his civic dash is from. Chances are the wiring harness doesn't exist, I don't really forsee anyone putting a civic dash in a different vehicle and rewiring everything to match in the Phillippines. Even if they left the wiring harness there, most likely it isn't connected. Now the question is if he has access to a junk yard or parts place where he can get a harness (at least the plug with a few inches of wire...) If so, then he could wire it that way. Otherwise, only way I can figure out is to just run wires directly to it without use of a harness. :S
swez on 02/8/2009 09:56:07
Agreed and that was the last ditch plan I was thinking too, with a few minor modifications. Since we don't know what he has and he may not know either, we can steer him into making his own harnesses and convert the HU amps to RCA type, line level signal lines for his amps. A pair of stereo Line Out Convertors will do that job nicely.

zanilth on 02/8/2009 10:48:48
Good point. Set of LOCs will definitely make things easier, he might have enough room behind the stereo to install it there and run RCAs directly to the amp. What about the scosche SLC4, it has RCA plugs for front and rear channel...Would that work for hooking up both amps? Now the question is does he have access to something like that... Not sure if the Phillippines has a wal mart :S
swez on 02/8/2009 11:16:15
We are tracking well. A 4 channel LOC and his exsisting pair of RCA's on this HU will give him 6 signal channels. (2 fronts, 2 rears and 2 for sub channels) The part we don't know yet, is that available in his marketplace? Only one way to find out... ask.

Not a bad deal here and he'll have gain adjustment features for each channel too. Time and patients will be needed to gain match all amped channels to desired speakers. This can be done by ear of DMM. (2-4 volts per channel is plenty for most amps.
