I am needing some advice on my selection of products... I got a Memphis 1000D which is 1100 watts at 1 ohm and the 10W7 is a SVC 3 ohm. Is this possible to use together, if so, how does it have to be wired and everything? Help please, it was my girlfriends christmas present.

you can still use this set up, not recomended though, you will not be able to get the power out of that amp you want. I would suggest ditching that w7 anyway. Look at some of the memphis subs they sound great,or Fosgate, There are some subs out there that will sound better than that w7, and who wants to deal with the hasel of the odd ohms on these subs. -------------

Whoa... I completely disagree with wheeler... There's nothing wrong with that w7... 3-ohms isn't a hassle either. Just connect it straight up... positive to positive, negative to negative. The 400-500watts you'll get is more than enough to drive a subwoofer. Your girlfriend gave you some really nice stuff (expensive - she must be hunting for the ring soon ;-)! There are actually few subs out there that sound better than the w7. You don't need to get full power out of the amplifier to get really loud. There'd only be a 3db max SPL difference between 500w and 1000w. This is tiny to the human ear... 99% of the time you'll never know the difference. Don't worry about not running 1000w unless you're going to compete in SPL competitions. Enjoy it, you have some nice stuff there. Two forum pros Steven, from Adire!, and forbidden, who owns two stores, think the w7 is one of the best subs on the market. https://www.the12volt.com/installbay/forum_posts.asp?tid=31055&get=last I happen to agree. ------------- New Project: 2003 Pathfinder

You don't need any help in selection of products....you just need help in enjoying them. But I'm sure you're girlfriend will help out there! That setup will rock.

This setup is FOR my girlfriend... not FROM my girlfriend... my setup is a Eclipse Titanium and a Memphis Mojo Amp, but this is my girlfriends Christmas present! Thanks guys!

You the MAN, DukeDuke! Most girlfriends are lucky to get a deck with a CD from Walmart and Pioneer coaxials.

keep your amp, give your girl your sub, take hers...merry xmas but seriously, no matter how you do it, that will sound good, just make sure the enclosure is done right

Wow .. that is a nice gift. Either you're REALLY lucky and your girl actually appreciates that kind of stuff, OR you drive her car a lot. Which is it? ;-)
Mine, unfortunately, couldn't care less and wants tiny stuff that sparkles.
By the way, I agree with 97Avalon, spend some time on the enclosure, it'll make a world of difference.

What do you think about the enclosure? Right now, the box is about 38Wx 12.5Hx 12D(at the top) and 15D(at the bottom)... (so it will be a wedge) if my calc. is right it will be about 2.96 ft3... (no I am not that bad with a measuring tape... it is going to fit perfectly in the back of her trunk) then I will add dividers to make it about 1.25 ft3, does that sound good to everyone? or not? any ideas? ------------- Duke Duke

You're putting dividers into a box that you already have (that is too large) to make it smaller for the 10W7? That would be wasted space, IMO.

It is just because I am wanting it to fit nicely in her trunk. Is that a bad idea? what is IMO?

In my opinion. It's the only web-speak shortcut I know, BTW. heh heh But that's cool, if she doesn't need the room for groceries and stuff. But I don't have experience with that sub to check the size.

why not make the unused portion an amp rack, you could keep the front only with a plexi window.

Actually.. (closing my good ole WinISD window) an internal braced volume of 1.25ft^3 sounds perfect to me. The Qtc is around .775 at that volume. This should be excellent for sound quality (transient response and extension). Go for it!

Because I am placing the sub in the middle, therefore it wouldn't be blanced... with an amp rack on one side and just a carpeted side on the other... I dunno, I just like to keep things balanced... and as well it is a Memphis amp, so putting it in little compartment, and closeing it up would make it more likely to overheat... which as everyone knows would make the amp distort... I had thought about that idea before... but I dunno... its just the fact of the balancing... unless I do purchase her a Cap... then it just becomes the overheating thing... it is a great thought however... I will add pics as I do more of the box...

you could easily put a squirrel cage fan in the box and it would never over heat. not to mention that d amps shouldn't really get all that hot, esp with a fan. I do appriciate the balance issue. although if you were feeling really creative, you could make the window into the amp box a circle and give it the same posiioning and size as the sub. thne back light the plexi with some leds and it could look real tight. just a thought, do post some pics of whatever you finally come up with

Well, this is just a box for now... she is getting a brand new S40 in 3 or 4 months, so I will do something really cool for her then.. this is just got now... but that is a good idea... I will keep that in mind when I do her next one.
