I have two door speakers that i don't want to put in my car (it's a POS), however, i am currently inthe process of putting together a surround system with as little money as possible (most of the components have been gifts or found in closests). My biggest concern is that the door speakers have 4 ohms and the receiver is driven at 8 ohms. Is this going to blow the speakers or damage the receiver? Also, I have two 10-inch subs that are meant for the car. Is there any way to convert these into home subs?

right now, while you read this, find some rope. go into the attic or basement & tie it around a joist. then hang yourself. really, its that bad an idea.

my friend had 2 10's in his room. that was fun in freshman year.

how about you go fuck yourself, i had a serious question, if it's a bad idea because it will blow the speakers or receiver then say so, if it's a bad idea because you think it's stupid, get over it

just looking to see if this is feasable or not

cyrion, did he have them hooked up to a receiver? was there a converter or something?

P=I*V
V=I*R

this is all you need to make this happen.

it's been 3 years since i've taken any physics classes, i remember those equations but relating them to the real world is still hard at this point
(graduating and getting a job does wonders for mentally erasing college classes)

many people do this or attempt this and it can be done quite well if you know what you are doing and depending on the enclosure

i dont know why slut is being such a slut

have you ever attempted this?

You can find used cheap dedicated home speakers for about the same amount of money as an enclosure to put your car speakers in.

10/23/2006 9:59:43 PM

slut is an ass but is is a terribly bad idea...

you see... car speakers can sound like shit because there are so many other noises in a car...
that and they have to compromise sound for space and low voltage and low impedance.

i mean i have $250 polk speakers all through my car and they're amped with a 350/4 jl amp.... and it still doesn't hold a candle to a decent home theater system and costs twice as much

no, i haven't attempted it before, but I dont' see why it can't make it work. I was planning on building just some simple boxes to house the speakers. My biggest concern is damaging the receiver and how to hook up the subwoofers, since they're already in a box and appear to be wired to be hooked up to a car amp. The subwoofer plugin on the receiver is for a powered sub, and my knowledge and home theater is not that great. thats why i'm trying to research some thigns first, before i wire it all up and i make cary explode along with Apex

thanks for the link, i will definitely be checking that board out this week!

well, i'm planning on building the enclosure to cut down costs. I know i could buy some cheap speakers (which may end up happening) BUT, my whole system so far has been pretty "rag-tag" and mismatched. I was kinda of going for the "unique" factor. My left and right channel speakers are my dad's that he bought in 1969 (and actually still sound really good!)

thanks for the input so far

10/23/2006 10:12:37 PM

^^thats a good point about the quality of speakers. They are MB Quart QM 160's. All the ones I can find online are just the 6inch speaker, these have a tweeter on them as well. these were given to me for free, heh, so i'm just seeing if i can make it work. the subs are Polk Dx series. but I can't imagine the quality of the subwoofer sound being too much of a problem with my setup as long as i can get them to work

10/23/2006 10:21:05 PM

when i asked "have you ever attempted this before" i was referring to slut

i understand speakers that are designed for HT are going to be "better" out of the box, but i think you can do some pretty good things with car audio (if they are quality) in a HT setting if you use the right enclosure

for all around good car audio and HT setups, check out the forums from the previous link i gave, elemental designs makes high quality stuff.

10/23/2006 10:35:04 PM

I took some old car speakers and ran them to my stereo to put in my bathroom so I could jam out while taking a shower/shit and they worked fine. I just mounted them up in the corner and ran the speaker wire back to the reciever..

10/24/2006 9:29:42 AM

you need a receiver that will drive a 4 Ohm load, they are easy to find I own a couple myself. Just make sure you wire the crossovers correctly to maintain the correct load on the receiver.

This really isn't a rediculous idea, it will work fine, may not be the best sound quality for home theater, but MB Quart makes great speakers, I had a whole car full of them back in the day.

Good luck with it.

10/24/2006 12:20:46 PM

^yeah, the receiver I have is a Kenwood VR-505 and it drives out 8 ohms. So, I COULD wire them in series but then it would only be one channel. I may just end up buying some cheap used ones at a yard sale or something. Now i just need to figure out these subwoofers

10/24/2006 6:20:18 PM

Actually, plenty of people do this when they're making their own speakers. Slut is just being a tool for no reason. I actually have an infinity reference 6023si sitting in the woofer enclosure of an old creative sub attached to a sony receiver and it sounds a clearer and louder then the system's native satellite speakers (on account that it has a bigger woofer and dedicated tweeter).

The key will be the box you build. Car speakers are designed to be in free air enclosures and when you build a tight box around them they in turn tend to sound a little boom - y. If you build the proper box though, then you shouldn't have any issues and they'll actually be better speakers then practically most of the shit you can buy at best buy. Receiver impedence matching is important though so you may actually have to run two of your speakers in series to increase their impedence.

Car woofers would also make passable home woofers as well but because car woofers are designed to be loud rather then precise, you'd have to get into the really really expensive shit to be able to match a home woofer. Still, if you build the proper enclosure and give it the power it wants then it will again sound better then any shit you can buy at Best Buy.

Of course, if your car subwoofer is B.A.S.S and your speakers are Legacy then just don't bother.

so what is the key to making a good enclosure for the speakers? I'm thinking a box with a sizable "hole" size thats basically how a door is. With the subs, they're already in a box, but the plug-in for the receiver is for a powered sub, so I can't just plug in the wires. I was also given a MTX Terminator Amp for the subs, but I don't see much use for that. The receiver should be able to drive the subs fine, it's just a matter of knowing how to plug them into the receiver

10/24/2006 8:10:00 PM

i, too, have debated doing this, but with the goal of creating a system to simply sit in a room at home...i have a car mp3 player that i've had for years, and i love it, but i got a new car and pulled out the stereo...i've wanted to set it up for a while now, but i'm not an engineer and don't know what to do about a power supply...that's my only concern

10/24/2006 10:36:37 PM

so have all of you come to the conclusion yet that there are three possible outcomes:

1. invest lots of time, money, research, etc & craft quality enclosures. results in decent 'home theater'
2. throw some shit together. it sucks.
3. combination of 1 & 2. sound quality/clarity/etc isn't bad, but its no match for an actual home theater.

10/24/2006 11:55:58 PM

1) time and research is not an issue, however money is. Yet so far on my "home theater" I have invested $16 and I have a kenwood receiver, a center channel, and the front left and right speakers. Unhooked up, i have potential satellite speakers and subwoofers. Building a box would cost me nothing but the cheap wood.

2)a. throw it together and it sucks? live and learn!
b. throw it together and it doesn't sound bad for my purposes? hell yeah, got a nice system for cheap as hell

3) I understand the difference between what I'm trying to do and what a "real" home theater sounds like. I've heard them, they sound great, but my purpose is to make something unique, inexpensive and doesn't sound too bad.

i can't see how any of those 3 options should deter me from doing this. the only limiting factor would be money, and thats why i'm seeing what i can do for cheap to get around that.

dude, go for it, don't let some asshole on the internet deter you from your dreams!

10/25/2006 8:15:39 AM

to answer your original question, he had to add a few things before it would work correctly. some guy in the dorm helped him do it. helpful, huh?

10/25/2006 8:46:41 AM

^very helpful!

^^there will be no deterring! that is, unless i find a decent powered sub for dirt cheap! and on that note, off to classifieds!
