Some questions about my system :)

[Joe5688 10+ year member]

Alright, im' running a 88120dvc aluminum and an alpine v12 mono 605. It's in a simple sealed q-logic box. I was wondering if i'm runnin it at 2 ohms wats the most you think my sub can handle. I know it has a 500rms spec but i'm not sure if i can run it that high. Also i figure im' loosing alot of sound and quality from my shitty box, but i looked around and i couldn't find any specs for my sub. I want to build my own box. I'm in to really loud base so what should my amp be set at as far as hz and fq. I got it tuned by some guys at bestbuy i know but it doesn't sound that great, it sounds shitty actually. Anyone help.

Thanks

Whats better then wat i got, it fits my sub perfect.. almost. And you didn't answer any of my questions

set you amp with a dmm for starters. i don't doubt it sounds like crap coming form bestbuy. whats the specs on the sub? coil config? specs on amp?

what are the specs of the amp?

you will gain considerable output by switching to a ported box.

Yea just toss out $ for a new amp, dont bother trying a new box or anything //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif.

PM Moe Lester, Jmac, etc. Ask them if they can get a plan for ya. Im sure they could, be like $10 or so. Well worth it, if you can assemble it well.

yeah i wont have a problems assembling it. Heres the specs

dmm = digital multi meter.

Digital MultiMeters

Those things should be your best friend with anything 12v (or higher for that matter).

I wouldn't give the alum much more than 600rms to tell you the truth. Your best bet would be to get a box designed by one of the 120948190348901323890 designers we have on the forums. Moe_Lester / Jmac are probably some of the better ones (IMO) won't cost you more than $10-$15 for a plan. Tune it ~32Hz or so (to keep it musical).

what do they need to know to build one?>

The max dimensions that you can fit, how many cubic feet you want it to be, what tuning, and how many in^2 of port you'd like would be useful.

i had the amp that puts out twice the power of that and only got 800w out of it wired at 1ohm, that was the 1005, i can only imagine how little power is coming out of the 605...

on the cea tag it says tested 669 RMS @ 2 ohms and is stamped with an approval? i ono wat the hell that means

i think i figured out what size box i need. I did some calculations for a sealed square box. I need 2 cu. ft. The dimensions i came out with were

External:

13" H x 18.5" W x 20" D

and internal:

11.5" H x 17" W x 18.5 D

this is using 3/4 mdf.

Does this seem righT?
