Well, it's already hooked up right now with 1 run of 12 gauge, and it works fine at 4 ohms with the gain about half way, but once I turn the gain up a bit more, the voltage drops into lower 12, sometimes 11 on really low notes, and when I max the gain (don't worry, the subs can handle it...maybe) the voltage is constantly around 11, and lower 10 on low notes. So, I really don't wanna get 4 gauge for a crappy install, I'd rather just get a capacitor and add some more 12 gauge, as long as I take a little time and do it good enough, I won't run into any problems. Hey, it's better than last time when I had a single run of 16 gauge that caught on fire under the hood, the wire I'm using now doesn't even warm up.

Yeah but I've already figured out that a bunch of 12 gauge will equal 4 gauge, if not more, so if I still have voltage problems after that, I'll just get a cheap cap, but I'm not sure what size cap to get. I'm thinking around 2 farad, the manual on Rockford's site says 1.5 farad, but I wanna get a cheap off brand one, like Boss or something.

Well it's not like I have anything seriously loud in there, I have 2 older 12" Orion XTR's, dual 4 ohms, 800 RMS each sub, and their in some crappy (really crappy) prefab sealed box, soon I'll be building a better box for them, probably around 2.5 cubic feet, tuned around 33hz, then they should open up a bit. Oh, and anyone know how big of a capacitor I should run with this thing? Needs to be cheap. Buy 4guage, and screw the cap? Ha, well, I'll admit, this isn't gonna be running on a stock alternator, but, the alternator in there now is worse than stock. I think it's 75 amps, and the amplifier uses a 150 amp inline fuse, so I'm just looking for a cheap capacitor to help with the voltage drops, because I know one of the main problems is the crappy alternator.

Is that true or were you just making a number? If 2.5 (whatever) runs of 12 gauge equals 1 run of 4 gauge, then I might just do 3 runs of 12 gauge.

That's what I thought, so it looks like I'm just gonna add some more 12 gauge, I would love to get KnuKonceptz wire, but I'm not doing a permanent install, this is just in my mom's suburban, when I get my car, then I'll worry about doing everything perfectly, but until then a few runs of 12 gauge will have to do.

If I could get my hands on some 4 gauge in my price range (free), I would.

Ok, I'm making myself look stupid asking this, because I pretty much know the answer, (no). But, what if I do multiple runs of 12 gauge wire from the battery to the amplifier? The 12 gauge wire I have is from Sears, I have 500 feet of it, it says it handles 600V if that matters at all. Anyways, my real question is, how many runs of 12 gauge wire should I use to power the amplifier? It's gonna be running at 4 ohms, possibly 1 ohm later, it's rated to do 750 RMS at 4 ohms, 1500 RMS at 2 ohms, and it's 'unstable' at 1 ohm, but these are the same amplifiers Steve Meade used before he got his new ones, and he ran them at 1 ohm just fine after removing a certain diode, which I might do later.

2 ports blocked should be around 23-24hz. 1 port blocked should be around 34-35hz. No ports blocked should be around 43-44hz.

Ha, sweet you're using my wallpaper. :bigclap:

Did the silver logo cost you any extra? I really wanna get one of these.

Nah, nothing new really, can you have a separate wallpaper for when it's rotated?

Bump!

Haha. "Do you think it's loud enough for a single, cheap 10?" "Did you just say cheap!??"

Can you post pictures when you're done with the box? I would like to see how it turned out.

Glad you guys like it.

That's what I meant, my bad.

Man how much power were you putting to them and what were you playingn to get that kind of excursion? (at work, so no sound) He has a Sundown SAE-1500D Prototype (I think), probably pushing about 500 watts to each, and the song is Hypnotize by Young Jeezy.

Dude that's f-ing sweet, glad to see my wallpaper is getting some use.

I'm pretty sure you don't need a fuse, but don't play your system for long periods of time without the vehicle running or it will kill both batteries unless you have a battery isolator.

Sweet, I'm very glad you like it. I'll make more when I come up with some ideas, I haven't been very creative lately, this is just a basic one I threw together really quick.

Might wanna get a higher output alternator, but I'm not sure on that one, if you throw another battery in there and do the big 3, you should be good, but I'm not positive.

Get 2 15" Fi Q's or BLs (Each are $264) and an Audioque 2200D ($389). They will wake up for sure, just be sure to put them in the right box.

Wow, that's an interesting one, I just looked at pics of the RD 1750.1D and the Sundown SAZ-1500D and you're right, the internals are exactly the same, similar cases too. Guess that would be something to ask Jacob...

Yeah I remember hearing that somewhere, I just forgot about it. That clears some things up...
