just get one of the marine sound systems, seems to work fine on boats 

the speakers are waterproof too so that's a plus

I'm more worried about theft,

By the way, since we are talking about intake, I was contemplating pointing my intake over to the passenger side of the engine bay area instead of down the front behind the driver side headlight. Only reason for me to do this would be to avoid water/mud puddles a bit better. Do you think its worth it?

I never did get an answer on this. Did anyone see this?

Hmm, that's what I have in my Jeep. 

[dwtaylorpdx]

Yea, I love those big windshield stickers proclaiming there is a good
chance of the car containing 10,000 bucks worth of audio gear. 

I usually black out the logos and labels so from outside the rig you can't
easily identify the radio. My YJ has a tuffy console that I lock when I park in the city. 


Oh yea, I wouldn't worry about eth intake position unless you go lower.... :)

No that ones going in the truck, the jeep just has some old Alpine 4x6 type s plates and 6.5 type r speakers and Alpine amp that I had laying around from one of my other stereo builds.  Its sad looking back at all the stereo stuff that I bought through the years and the money I   I used to have an alpine indash moniter and dvd player, alpine and sony head units, some jbl gto 5.25's and some kenwood 6.5's, along with a cd changer and 4 channel amp all just layin in a drawer collecting dust... I have been trying to get rid of some of it so i have less crap to pack up when it comes times to move

ALRIGHT ALREADY! ENOUGH ABOUT THE STEREO TALK! Now, lets get back to business. So you dont think that moving my intake from behind the left headlight to the right side firewall will make a difference if I was to go get into some big ol mud puddles?

why would that make a difference - i don't really see how that would help (so maybe explain in more details). I think TJs came with the airbox on the passenger side, maybe you could use one of those setups if you want to change yours

[TrailsLessTaken]

Would you keep it as an open filter or would you run like a tj ait filter box?

[dwtaylorpdx]

I'd use the air box, I don't need any more noise....
And There is no discernible power increase that I've been able to see.
I think its a CFM vs RPM thing. Our engines just don't tax the stock air box that bad,
especially if you pull the baffle out of the inlet and the air pipe depending
on the combo of parts you have.

I put the baffle back in.  I notice a big different with and without it.  It raises the power band about 300-400RPM's.  Since I do most of my driving in the 'city', I figure I could use the lower torque more.  It will still spin up to 4000RPM but it gets a bit more winded then before.  I'm not sure if it will freely spin up to 5000RPM anymore.  I've been bouncing back between using the baffle and removing it for a while.

Oh and the whistle goes away with the baffle in place.

Guess I need to clarify a bit more. I have cold air intake with a cone filter. The filter is set right behind the drivers side headlight and I have seen people turn the tube so it is paralell with the firewall and the filter points down behind the front passenger wheel. Reason: If I were to run into some mud puddles that splash water up into the engine bay, I wanted to keep it away from the filter. Make more sense?

I don't think it's a good reason to move it.  When you run into water or really wet mud, you'll be pushing a bow wave.  The depression will be around the front of the jeep but soon rise as it reaches the rear of the engine compartment.  Moving the filter over to the passenger side will also introduce it to hot air since it has to pass over the engine.  Not to mention, for every day driving, the area near the firewall will probably be a low pressure zone which collects hot air.  If you're afraid of splashing then make a splash shield.

[jfrabat]

Just out of curiosity, but if you are willing to fab this up, why not just fab up a snorkel?  I remember seing one somewhere online made with PVC pipe and a cookie can to put around a cone filter, and it looked quite nice...  This way (1) the intake air will be colder (taken from a higher point, where it is less affected by the temp of the road, as well as coming from outside the engine bay), and (2) you will have less risk of hycrolocking the engine on the mud/water holes.

[Steve-0]

I wouldnt be fabing anything, just turning the intake tube. But thats not a good idea. A splash guard is exactly what I was thinking. Probably can bolt it up right at the airbox support brackets.
