1998 Camaro Install- lots of pics, rear seat delete - Page 3

the reasoning for adding it would be to make it flow a bit more. I'm getting a 7202 or 7252 for the other side so it'll look the exact same. The reason i said fiberglass was so that i could make the whole thing one piece, but i would carpet it because i want it to just flow and not stand out. Why is it that you don't think it would make a difference by putting a cover on it?

Another idea would be to bring the box up a bit and sink the amps into the box( maybe at angles?), i would still bring it up to the sides.

Looking good there, one of the better out-of-case installations I have seen so far - quite tidy wiring, keep it up.

Luv it

Getting a matching amp will go a long way as far as looks go.
The reason I don't think a carpeted cover would make a difference is because it looks pretty good right now. It just seems almost impossible to get anything to blend into those side panels unless you mold them all together into a single piece.

Another thought, is to turn the sub around and then build up the middle part of the box about 3"-4" so that the magnet will actually fit into it. Then you could make a one piece, flush cover with cutouts over the amps to show them off. Is that an option or do you like having the sub magnet exposed?

Actually, I kind of like the smoked plexi cover.......

I was going to box mine and carpet, but now.......I may have to rethink that.

Also, I notice you have a dell. I'm using a dell optiplex 260. Did you have to check the pinouts for your PSU or is it a standard 20 pin atx connection?

Cheers

sporty_drew · 05-05-2007, 08:36 AM

it's a standard 20 pin.

Well as for the whole turning the sub around, I was looking at different subs last night an I'm thinking either 2 10" G5's or 1 12" G5. I know what you mean when it comes to blending something to the side panels, they have a weird curve.

JasonWW · 05-05-2007, 08:55 AM

How much air space is in that box? It looks like 1.2-1.5 cu ft.

Who makes the G5?

I'm really leaning towards sticking with 1 12 so i can keep the amps on the sides. if i would do the 10's i would put the sub amp in the middle and the speaker amp on the back "wall" in the t-top holder.

JasonWW · 05-05-2007, 09:35 AM

Dang, in looking at the first post again I see you already mention the size of the box. Oh well, at least I guessed right. So both of those amps look like they can run 2 ohm stereo or 4 ohm mono. If you got the single 12" you could bridge the amp and run it 4 ohm mono for the most power. I like the single 12 idea, but the dual 10's should work well in that box too. For the 10's you'd need to get the dual 4 ohm version. Then you could wire both into a single 4 ohm load again. Is that what you were thinking?

It looks like a single amp could power one sub really well. 450 watt amp into 450 watt speaker.

sporty_drew · 05-05-2007, 08:47 PM

I was actually thinking of getting the dual 4 ohm 12 and running it at 2 ohms, just set my gain accordingly. The 9102 can run 2 ohms mono and 4 ohms stereo. i could get the dual 2 ohm, but I've never like the wiring configurations for dual 2 lol.

JasonWW · 05-06-2007, 08:50 PM

I don't think they make the G5 subs in dual 2 ohm. I thinks it's either single 4 ohm or dual 4 ohm. The 9102 is a mono class D amp. It will run mono 2 ohm or higher, but not stereo.

It's true that you could get a single 12" in the dual 4 ohm style and then wire the coils in parallel for a mono 2 ohm load. Are you sure you want a class D amp, though? They kind of just flop the cone around with no real control over it. I always stick to class AB for good control and sound quality.

I think i'll get the dual 4 ohm. I didn't know that with the class d you lost sound quality compared to an ab. i knew they wasted more energy. I'm going to read up on that more.

I've also decided that I'm tired of my onboard sound. I'm going to be getting a pci sound card and I'm going to look at equalizer software. if i don't find anything i like I'll get a sound processor.

Thanks a lot, it's a work in progress

A good PCI card to get is the Chaintech AV-710. It is really cheap at under $25 and channels 7 and 8 use a very nice high end Wolfson DAC. The 2 channel sound quality is really nice. It also is good at hibernating and suspending.

I'll look into that card. what is a good output level to look into for a card? I've been reading up on RedGTiVR6's card he's making and Durwood's project. I've also looked at that link to the free software a few times but i don't understand exactly what i need and how it works with processing the sound after leaving winamp, i definitely need to do some searching on that.

The output level isn't of any real concern. If your going straight from the analog out to an amp you would adjust the amp gains to give you the volume you need. What stereo components are you running right now? Does it go from the PC straight to the amps?

Red, BTW is a girl. Her name's Jan.

I don't fully understand all that software EQ stuff either. I use a Alpine H700 and it does all the x-over, EQ and time alignment seperate from the PC. I kind of like it that way.
