well im on a budget here also... i would like to only spend like $50 bucks on a power supply. and i really dont plan on using an amp and its only 4 speakers. well actually 6 speakers cuz we have 2 outside speakers i will hook into it also. the HU is 200 watts max. 50x4. so what would work for that in my price range?
Erk, you should be able to get something for that much, if you want a real nice piece of equipment for that much you might have to go secondhand. So that is only 20 watts RMS or so per channel, that could work with maybe 8A or so.
You could probably sell the HU and buy a nice home audio amp. It doesn't have to be anything new, just search for some Technics or something older like that on eBay.

You know that impedance will change your crossover frequencies right? It would be a good idea to figure what your final impedance is before you go picking out crossovers.
Or actively cross them. Infact, that's probably his best choice in this case.

I'm thinking maybe some Dayton xo2w's but idk. Any suggestions? And another thing, if there is an amp out there that would provide adequate power for these towers that didn't break the bank, I would be interested in knowing of such a thing. Any and all info you guys give me is appreciated. And the speakers are just some GRS 4"ers. Nothing special but I did make a center channel with my four extras and it sounds great.
Is that crossover matched to the speakers you are using? And are the speakers matched to each other? Trying to mask a badly designed speaker's sound by playing ti loud doesn't work too well
.How much power do you need? And what's your budget? (we don't know how rich you are
) -
What is with you people and using PSUs with 3.3v, 5v and -12v rails? You only need one with 12v rails, not the extra ones that would be used in a computer. Besides, I think that the PSUs work at their best when the either the 3.3v or 5v rails have a load on then, I can't remember which one it is.
A PSU with only 12v outputs may cost more, but it will work better, and won't be as much of a pain to wire up.

here is the power supply i will probably be using, http://www.frys.com/product/6366531?site=sr:SEARCH:MAIN_RSLT_PG, but i built my box on google sketchup but i dont know how to add the file on here... if you want to see it tell me how and ill post it.. but do you think that PS would power an amp? im not planning on using one but maybe in the future...
That may not even be able to power a HU properly. You'd probably want 6A for the HU to run it with enough headroom. The PSU I've been using on the 50.4 has dual 35A (or 30A) rails. So you would definitely not be able to run a amp off that PSU.
-
actually i did some looking around and found a regular ac-dc power supply for like 30 bucks. im going to pick up one of those, its like the same price and i wont have to mess with switches or possibly burning anything up.
How many amps can this power supply...um...supply?
-
What are these said crossovers? They will sound like rubbish if your crossovers aren't good. Crossovers can make or break speakers. What enclosure specs were you thinking of using? As Iceman said up there ^ what speakers?
-
You could always get a ThermalTake PSU. They have single 12v channel models and don't cost all too much for such a great product. I have powered a class A/B 50.4 bridged into 2 4 ohm channels, the voltage barely dipped below 12v. The lowest I saw was 11.8v I think, that would certainly be enough for a HU.
-
Just get a Stetsom 7K2 and be done with it.
Also, if you were going to run the subs off one amp you'd need to go for dual 1 ohm coils. For two amps, dual 2 coils will be fine.
EDIT: you don't run 7K to one sub, you run 7K to both. And you do it because the subs can take it, and because it makes the people here get excited. Haha
-
DEAL!
Lol, ok then.
It's kicker stuff, so im assumign they are D4...
But reagrdless, check out sundown amps.
A 2000d will kick their asses.
I like the pun.
yeah sundowns good i would say 2000d if there 15's
and 1500d if there twelves

I check my News Feed, so my posts are everywhere. They're mostly in General Audio though.
The last to posts were helping you understand how I post
I probably don't remember them because when I read through a thread I go 'damn, hdorre beat me to it again!' lol.
Haha, true, paypal me $5 if I find a post that isn't helping someone? :-P
-
Lol, Atleast I don't post dump
You accusing me? Haha.
It's still funny how you have 1,000 more posts than me and we joined only 2 days apart.
No, I wasn't accusing you. I was just stating that I get my posts by actually helping people. I don't mean that you don't. Haha. Its hard to infer what I meant over a computer
I didn't even notice that were only 2 days apart. Lol. That's crazy.
How come I never see half the posts you make? What section are they most in?
I know what you mean though, it's hard to get the way you say something across.
In those 2 extra days you made 1,000 posts? Haha
BTW, who were the last two posts helping
^jk of course

How many ohms are the coils going to be?
Running one amp should be easier to set up, and it won't suck as much current from your electrical.
-
What voice coils?
I just realized, you post far too much. You post whore you
. all good.OP, you need to post far more info, you don't even say what size L5, as I believe each size has a different power rating.
-
4 12"s should have more motor force than 2 15"s, unless you were comparing 4 lvl 5 12"s to 2 Sony xplod 15"s. Haha
Go for the 4 12"s tune to 35hz, make sure the port has sufficient area and is squarer (like hdorre said) and make sure that the port is it's height (at least) away from the back inside wall of the vehicle.
EDIT: about the RE subs, they are made in china or something now, so they aren't as good as they use to be. The MX, MT and XXX are still the same as they use to be I think though. So you'd be safe with them.
-
Fused your alt wire? That isn't really necessary, just make sure that the wire to the back where your amps are is fused. And tuck the alt wire somewhere safe where it won't touch anything hot and where it can't rub on anything moving.

i looked into it and its going to be about 8 or 9 cubic ft. i could go higher, as long as i can see behind me while im driving (only reason i dont want a wall)
try around 11-12 cu ft for 2 18s.
hmm, 13 after displacement minimum I reckon.
damn it that was supposed to be half wall.
haha, I know.

2 18"s=bigger still
wall wall is the dumbest term ever. just say big as box in the back seat.
wall wall? yes, that is the dumbest term ever

How many did he put in his ride
Like, 14.

I was wondering if anyone was thinking of making a SMD iPad/iPhone app, I'm pretty sure it would be pretty popular, especially since there are so many members on here.
Home theater shack has one, so why can't we!
People like you.
In all seriousness, why? You can access the site on Safari, no need to waste time making an app that maybe 500 people will use.
An app could have everything in one place, making it faster and easier to use. Plus, the stupid garage section up the top of the page is 2 cars too big, it makes it a pain to use TBH. It's a cool idea, and having it is great, but it isn't set up the best.
The site has everything in one place.
If they make one I need an app for a windows phone.
That's one of the issues with making an app, you have to learn to port it to Windows phones, iPhones, Android phones, etc. Web based is probably the best opinion.
There are some things that could be changed in an app to make it quicker to navigate.
Yeah, but it could be a good project for a budding software engineer.

If you are going to use 2 18"s, I'm pretty sure it is going to need to be bigger than a half wall. I'd say 3/4 wall minimum. Or just fully wall it.

all good.
computer power supply for gerage system?

Just look at the specs for the +12v rails. Make sure if it has multiple ones that the identical ones add up to 8A or greater, as it is not really ideal to link two unmatched rails together. I'd say 8A minimum, you should be able to easily get more than that.
Don't worry about watts, they are normally rated for the total of the PSU, not the 12v rail output. I said 8A because that's about 20watts per channel minus efficiency.
