I'm too audio retarded to post anything worth reading. If it weren't for Sean, I would be running two DIYMA 12's for a high output setup. I can't imagine what my box would look like if it weren't for Sean and Kent. I have a lot to learn

What's the matter? Do you think people don't want to hear with your issues with customs???

Gah I hate that guy. I had one in my Linear Algebra class that would agree outloud, thank goodness he skipped class all the time and thought it was cool I was a nodder, but of a different type. Falling asleep makes me nod. I hope you weren't sleeping in the first row like one of the guys at the calculus lecture. The prof even took pictures of him sleeping. better then getting caught drooling Hey Romanian, did your German buddy get my email yet? Havn't heard anything back since I sent it a while ago.

thanks! ....tell your avatar to quit flicking me off and take off her shirt

Cool. I had someone that knows what they are doing (10 years of install work) help me out. He's a hike away, plus I would rather not bother him if I can do it myself. Does anyone have a D3 and know what color the ground is? Thanks for the help guys.

I've heard a lot of people complain about the same problem, but what do I do to solve it? If, I need to reground something, which wire/s go where? I'm not too knowledgeable about this nor did I install this on my own. My truck is an 06 Silverado

Nope. I pulled my signature move of raiding the chicks' refrigerator before I sneak out while she sleeps. Probably a dangerous move stealing food from a fat chick though

not sure what caused that guy to make that face but I think I made a similar one when I woke up next to some heffer I met at the bar two nights ago.

Well, I'm off to home depot to get my wood. Hopefully sometime during this trip, I will decide between upfiring and downfiring haha. Last questions, for now...... will the carpet on the floor muffle the sound enough to the point where upfiring might actually have more output (especially since there is only about 1" of clearance) Is there any point in tilting the sub so that it fires toward the opening? This would sacrifice clearance on the other end of the sub though.

I imagine you are looking at the ipod interface as well? Try to tget to a best buy and hook an ipod up to mess with each unit if you havn't already. I forget how the Pioneer was, but I did not like how the Alpine did not display several lines of text so it made scrolling through music harder. Just some food for thought Alpine does have a neat percentage search function to get through huge libraries fast.

Sean, do you agree with Kent that not a whole lot of output would be lost if I upfrire rather than downfire? I have been reading up on the difference between the two (acoustically) and it seems like the output difference would be more dramatic if the box downfired onto a hard surface, not as much on a 'squishy' carpet. What do you think? Obviously I'm not looking for a unit of measure but just a "no, not a lot of difference" or "well, there will still probably be a substantial difference"

Ok, you say I need 2". Is that for the feet, or is that for the distance between the surround and the carpet? I think I can get feet that are 2" but the surround extends .8" from the baffle not even under power so 2" feet gives 1.2" clearance. Make sense? You are right about being able to increase the rear height of the box to 8.5", but I have to move the box in about 1" on each side to avoid hitting the seat frame....not a big deal.

Fortunately the RL-p does not require too much air space, so I can actually get away with using 1/2" and then gluing that to more 1/2'' (so 1") for the entire box EXCEPT for where my sub is located because of the mounting depth. My RL-p has a bit more depth than your ICON; about 1/2" more so those 2'' feet will have to be cut to 1.5''. Kent, in your opinion, will this work? If not, I will either sacrifice output and do an upfiring box or have to tweak some more to see what I can do. O yea, kind of important: how much clearance should I leave between the magnet and the top of the box? Or do I not need any? Thanks for the help guys. In a way, your opinions are complete opposites, but I'm valuing them both a whole lot in trying to get this project designed and built. Hell, maybe I'll build one design and when I get the time, build the other and sell whichever I don't like as much. I guess that's what this hobby is all about anyway: trying out different things and never being satisfied.

Actually, I can increase the thickness of the problem of the baffle no problem, so that should not be a worry. The 7" mounting depth plus 3" clearance seems like it might be impossible though.

Also, the Xmax of the RL-p12 is 1". For this clearance, do I measure the floor to the top of the baffle or is it from the floor to tip of the surround? If that was confusing, the same question could be asked: Is Xmax measured from the baffle or is it measured from where the surround lays when not under power (off)? There's about a 1/4" difference between the baffle and the surround and like I said, I'm having some issues with mounting depth, so I'm really shooting for the minimum clearance the sub will need.

Will it make a huge difference if I use 1/2" MDF for the mounting location as opposed to 3/4" like the rest of the box? I am starting to worry about mounting depth. Kent, the back of the box is only 8" tall so how did you get your required mounting depth? 8" - the 1/2" MDF thickness (times two) - the 2" for feet = 5" I understand if you mount the sub as close to the front of the box as possible, I'll have a little more than the 8" but I still don't see how you found 6.5" for your ICON....let alone the 7" I need for the RL-p. Also, will fiberglass eat through Al foil? I'm worried about getting that slop in my truck so I might paper mache a mold and then fiberglass the mold. Rabbit wire might work too for a mold Oh yea, I am only going to do 1" feet to help some. Is that enough space for the sub to 'breathe.' It's max excursion is rated to be a little under an inch so I'm sure I'll be ok with that but I'm not sure if more room is required for sound clarity or something.

3/8" hole already there for me and I have already bought the grease and undercoat. Good to go...... I just remembered I need a rubber grommet....son of a.....

Are you doing something special? Just post the dimensions and someone will be able help you out pretty easy. I'm about to build my first ported box this week and have been getting an insane amount of help from people on here

For mental image's sake, I have an extended cab Silverado w/ the amp mounted on the back wall. So, how about if I attach the ground wire to a bolt going through the body, and then have another run of wire underneath my truck from that bolt to my frame? On the Silverado forums, people say grounding to the body is a big no no. Perhaps this is vehicle specific (such as our trucks having a history of bad welds or something). I'm still thinking running the 1/0 through a grommet straight to the frame would be best though. 4' does not seem like it would be a problem, especially since my power is 9-11'.

If I shorten my ground, I'll have to ground it to my body. I would have thought grounding to the frame would be much better.

If I can get back to my parents house in time, I'll be mailing a 28lb Amp and about another 12lb jeep cover to Romania. Speaking of which, Adrian D, what do you want me to do for insurance? The jeep cover is a narrow box about 5 ft long and you can all picture the box an 2 ft amp would go in....anyone know if USPS will let me duct tape them together? Either way, I'll repost the shipping charges. If I can't get there today, it will be tomorrow; no later.

I have a JBL BP1200.1 powering a rl P-12. From battery to amp is about 9 ft and ground is about 4 ft. The amp's plug looks like its for a 4ga. Should single 4ga runs be sufficient? if so, who wants to buy some 1/0 and sell me 9 ft of 4ga??? (from the old setup)

wtf!!!.........mom???

Happy BDAY! And for your birthday you can get me those box dimensions I always wanted

you guys are really making him work for your advice
