Hell, if I'm going to use only one sub then I may as well just go back to mounting it in the back like so:

It's more efficient use of space as the duct won't be needed. It makes the whole back seat area less overbearing and more rooming feeling.

Having one sub and the PC side by side just didn't seem right plus it messed up the vent calculations. With a single sub I'd rather have it the center of the car as it just seems better.

Now if I can just cut a hole on the rear deck, over the gas tank and sink the speaker magnet down into it to lower the overall height.

Actually, facing the sub to the rear would probably be best. Believe it or not, but it doesn't block the rear vision when looking through the rear view mirror. I can mold the enclosure so it's only as tall as it needs to be and on either side of the sub it can slope down so the bass can fire backwards and then come around the sides and back towards the front. In my SPL testing this seems to work very well and I wouldn't need to seal off the back storage area. Plus it would look good when you pop the hatch.

hey guys, in the interest of getting things back to fbody related ideas, who has actually installed the mobo and whatnot behind the screen all in the dash? i'm considering doing this, as i've yet to find a good spot for the box.

And what have you guys been doing for CD drives? Slotload is the order of the day i assume? but where?

and radio? I hear the radio tuner cards kinda suck, like much worse than the stock reception...

JasonWW · 10-23-2006, 10:33 PM

Didn't I already answer all those questions? Check earlier in the thread. I think I answered all 3.

If you put the PC next to your sub I'm sure your ram or any other magnized devices in your computer case are going to hate you...at least a wee bit.

jrtf83: I didn't put my mobo behind my monitor, but I stuffed my head unit behind there...that way I could control my radio with my steering wheel controls and I could listen to the radio while my computer boots up or if there is any problems with the comp I don't have complete silence while the comp is down. I put a "lite-on SOLC-241k" slot load cdrw/dvd in my glove box. I found a case for the dvd player on ebay that converts that makes the dvd player run off of USB (it has a power usb and a data usb). i will have some pictures up this weekend...I think it looks sweet (my comp is in the cubby hole in the back).

Well it took me a couple to hours to resize and crop pics and write it up, but here is Part 1 of the climate control relocation I've been talking about.

Yet another diagram of the latest idea. I know, your probably sick of seeing these.

I was thinking, if 600w is plenty for each of these subs, then why not get 2 12's? In this location the 12's would be lower and offer more visability to the rear plus more overall output for the same 1200 watts. I'm looking into the Rockford T1 subs right now and this power rating seems to fit them better.

A lot of folks comment on the T1's absolutely pounding in a ported enclosure tuned to about 30-35Hz, so I figure I could try a ported box. I could add a 4" port on the outside and then adjust the port length to the right freq and what sounds best. My Alpine H700 can set a subsonic filter at 30Hz or whatever with a 36 dB slope so that it won't try and play anything below the tuned freq. If I don't like it, I can seal it off.

If I decide to keep the port, the actual fiberglass enclosure will have the 2 12's facing the rear. The port can extend up out of the box and fire to the rear, exiting right in between the subs. With it all molded in and curvy, I think that would look pretty cool.

Any opinions?

It seems like I answered all these questions just not too long ago, but it was bothering me so I looked and could not find them. It might have been a PM that I answered and deleted, I can't remember. Anyway, I'll answer them now.

1. Look at Snootch's system on page one and follow the link for more info. Not very many people install the mobo in the dash. If your mobo is small and doesn't generate much heat you can probably do it. Those small micro ATX mobo are either really expensive for the fast ones or too slow and weak for the cheaper ones. Glove box mounting is also an option. If you have a camaro you can mount a slim PC under the passenger seat.

2. Slot loads are the definetely the way to go. Where you put it may depend on how often you plan to use it. If not very often you can put it in the back of the car. If your set on putting it up front you can put it in the glove box, mold it into the dash or under the drivers seat. You just have to look around and decide what's best for you.

3. I don't like local radio with all the commercials and such. It's better to just get a XM setup and control it through the PC. That way you can see all the station and song info, have it look more integrated and control it from the steering wheel. There are XM tuners that connect through USB, serial port and I think there are some PCI versions as well.

Hope that helps.

OK, I made a few mock ups and snapped a few pics. I just want your opinions on the overall look. I want it to be different and I want folks to be impressed when the hatch is popped.

Here are the 2 12's:

Here is the single 15:

I think I prefer the massive look of the single 15. Here is the view of it looking over my shoulder like I would normally do when backing up and through the rear view mirror.

These aren't bad at all. I could live with that. Here is the fiberglass box shape I would go with:

What do you like?

turbocad6 · 10-27-2006, 10:07 AM

that does look pretty intense with the one 15.... the 2 12's looks nice too... I think I would choose the 2 12's for just a bit lower profile & potentially more output, but that don't mean the 15 is bad at all... either should be sweet... I'm just thinking that you haven't acounted for the box quite as much as it'll actually be, & it may wind up just a little bit higher than your mockups, that 15 is pretty high up

that's gonna be a sweet setup man, I like this more than the original idea of having the drivers right behind the seats..., not that it couldn't work, but this is a bit more of a sure thing I would think

turbocad6 · 10-27-2006, 10:09 AM

then again, if you dropped the front lip of the sub slightly over the edge, you cound get it down a bit extra, & the 15 may also work out well....

hmmm, decisions, decisions

JasonWW · 10-27-2006, 10:23 AM

Yes, I'm favoring the 15 as well. I could definetely extend it over the lip to drop it down a little more if I needed to. I figure I could move the ports up a little and use large flares on the ends.

I wish there was a 4" valve that I could install to open and close the ports at will. I could easily program the Alpine H700 to have a special setting for the ported box with a steep 30Hz filter and so forth.

You mention that the 2 12's would be louder, but I think the one 15 with 1200 watts on it would get it loud enough for me. Especially with it ported.

I'm still trying to figure out what sub to go with. If I had a way to power a single 4 ohm load I'd probably get a Sounsplinter Supreme Series LMT 15. The response curves are amazing.
http://www.soundsplinter.com/rls_ser...formation.html

But I have 2 600 watt amps that need a dual 4 ohm load for max power. So my favs right now in order are:
Rockford T115D4
JBL 15GTi
Eclipse SW9152

I believe the JBL may be tops in SQ. It BTW would get 900 watts due to it's 6 ohm coils. It's supposed to sound a tab better than the JL W7's, a bit cheaper and be a couple dB louder, so that's all good.

JasonWW · 10-27-2006, 10:30 AM

Oh yes, another good reason for the single 15 is that you need some room on the sides for the bass to travel around the glass window to get to the front. The 2 12's are somewhat sealed off because they are so wide. Especially with the port making them even wider. The cone area to gap around the subs ratio is kind of bad. It may even reduce the output some. The single 15 has a much better ratio so the bass will flow around it to the front.

turbocad6 · 10-27-2006, 10:47 AM

yeh, your right about that, didn't think about that really, I guess the 1 15 sounds like a plan...

I know what it feels like to be restricted because the amp is already selected, I have the same problem really, I REALLY want to use my mc4000m, but it does really limit the subs I can select from....

Is that the 6 channel?
300wx2 plus 100wx4
Are you only running that one amp?

There seems to be a lot of new amps that are for subs only and are very efficient. Class D maybe class N or something. They don't play the upper freqs and are very powerfull. I could sell 2 of my amps and get a new single unit if I wanted to.

I've heard a few good things about this one:
http://www.massiveaudio.com/lowband/...pro/p3000.html
For under $500 it's a lot of power. I'm just scared of these amps as it may not have the SQ I expect.
