Cabling car speakers as home speakers (is it really that stupid?)
When I was younger, I used to play a fair bit with car speakers and connect them to my home Pioneer hifi separates.
I blew a couple of speakers in this way (as you do) and when I discussed it with an installer a while later was told that this was due to the impedance on the car speakers being 4 ohm and the house speakers being 8 Ohm. He suggested 'wiring the speakers as a pair' in parallel or series - I forget which, but basically I think he meant splitting the source wire into two sources and then feed to a speaker each one. This should in theory bring the total impedance to 8Ohm. Now I am all grown up (36) I am looking to install a home AV system around several rooms in the house and am wondering whether or not I could use something like this to utilise car speakers in the ceiling in place of very expensive house speakers which are fitted into the roof (they all seem to be over £100 \ £150 a pair!!)
I'd like some common sense advice here please, is there a way I can wire a pair of car speakers to provide some sound around the house (cheaply) or do I HAVE to go with dedicated 8Ohm house speakers for the job. Aside from anything else, it seems as though there is an awful lot more choice when it comes to car speakers than there is for in-ceiling house speakers.
Is it bad for the speakers, or amp or what?
I'm looking for background to medium type noise levels etc, I'm not turning the house into a nightclub!!
Thanks in advance guys!!

Re: Cabling car speakers as home speakers (is it really...
If you wire the speakers as a pair in parallel; (For two 4ohms car speakers)
1/R=1/4 + 1/4
R=2 ohms (the resistance value you'll get) (don't even think of trying it!)
R=8 ohms (this mostly fits to home amplifiers, however, they provide 6ohms as well)
I recommend that you use reasonable 8ohms speakers for the home theater amplifier you have. Despite the fact that the impedance value fits to 8ohms when you wire two car speakers as a pair in serial, this type of connection will tire your amp as well as the capacitors of the car speakers. Furthermore, you can get unwanted peak sounds from car speakers.

Question: Although you can get good sound with the car stereo speakers using EQ (and maybe a notch filter or two in the crossover), will you get good dispersion? Car speakers are designed to operate in an enclosed air space in front of the cone (the car's cabin), while the back air enclosure is either very limited in size (a door, for example) or VERY spacious (a trunk). Those considerations make me wonder if the dispersion will be less than optimal.

I can't find a picture of it/them but in general you want to get the BEST audio to your hifi electronics and let stereo-only TV-related audio go TO the TV itself.
FACT: TV speakers are there as a convenience. If they were comparable to hifi electronics and speakers we wouldn't by anything but a TV, right?
CORRELARY: TV is not itself an audio source. Everything it displays and projects soundwise comes from somewhere else at a higher 'fi' than it can reproduce.
So, get your BEST satellite or cable box digital audio out through either coaxial or optical cables to the Pioneer, if it has compatible inputs. This way you can decode multichannel audio broadcasts in electronics designedf for it.
There will also be a stereo pair of RCA jacks at the Sat/Cable boxes that you can run to the TV if it has multiple analog audio inputs. That way you can watch and hear CNN or the Weather on the TV without cranking up the Pioneer.
If you MUST have a TV audio feed to the Pioneer, use its RCA analog audio out to any available input. The TV may have internals controls for volume at those jacks. I recommend choosing a FIXED output level so you can turn the TV speakers down or off and still listen through the Pioneer. But it will be in vanilla stereo only.
<p>The Pioneer PDR-609 is a personal CD recorder used in
conjunction with the rest of your home audio system. The equipment has a few
audio inputs, however, so you can connect external devices to play through the
Pioneer PDR-609, including an Apple iPod. You need a special adapter cable, but
once connected, the sound from your iPod through the speaker Pioneer system. <br />
<p>1. Connect the end of the cable 3.5 mm headphone of your
Apple iPod. <br />
<p>2. Insert the red and white RCA cable ends into the
"Line In" port on the back of the Pioneer PDR-609. <br />
<p>3. Power on the iPod and the Pioneer equipment. Select
"Line In" as the display option in the Pioneer, then the song you
want to listen to your iPod and press select "Play". The music now
plays through the speaker system of the Pioneer system. <br />
If you have good clean, loud sound with your LP player and not with your PC, your PC is causing the noise. Most PC sound cards are not very HiFi in their sound and it is quite evident when listening to a PC via a HIFI sound. Now, you can not use the headphone outputs to your Pioneer, you must use the LINE OUT jack, set as line out in your computer. There is a signal level mismatch if you use your headphone outs, distorting your Pioneer. Try LINE OUTs or buy a HiFi rated sound card.
like the 3.5 plug is mono or the plug is not completely inserted in the computer
jack (push it in until you do not see any more of the contacts). I connected
one of my computers to my stereo receiver and used a splitter so I could use
both my computer speakers and the stereo without disconnecting any cables.
First make sure your 3.5 jack looks like the one in the link with three
contacts and two insulators (the black plastic piece). http://www.cablestogo.com/product.asp?cat_id=2009&sku=40421#
If you see only one insulator and two contacts it is mono and the
second channel will be shorted out.
I would recommend using the Front Line Out which is a pre amp output
into your auxiliary input on your home amplifier. If you use the headphone jack
you may have clipping of the signal causing distortion.
Use the cable similar to the one in the link below or you can purchase one
at Lowes or Target. http://www.cablestogo.com/product.asp?cat_id=2009&sku=40427#
Plug the splitter male jack into the into the computer Front Line Out
and the computer speakers into one female jack.
Second connect an 3.5mm to RCA stereo patch cord to the other female
jack of the splitter. If you have a 3.5mm to RCA mono purchase one similar to
the link below. http://www.cablestogo.com/product.asp?cat_id=2009&sku=40613
Red left to Red left speaker Black left to Black left speaker
then repeat for right speaker
turn on amp play somthing quite to start, check all is working. To check speakers are in phase play a bit louder and stand exactly in middle, bass should be defined and central, it helps to close eyes and listen. If not central and defined change over Red and Black on one side only then listen again with the same test.
Start flat with eq section adjust as you like when listening to something you know and like.
sorry no easy solution as it sounds like the output transistors blew out or the emmitter resistors. you will need a service manual and an multimeter to measure the resistors on or around the audio output transistors they are a low value resistor usually around 1 to 2 watts in size. Do not replace any bad , burnt or discolloered resistors around the audio output transistors as if tou do you might just cause more damage to the output transistorsor audio output stage including the audio driver stage of the amp!!!!!!

no it can not. the sound card in your computer has no power behind it, only a signal. the acoustimass needs power from an amp. you can connect your computer to a home theater reciever and get what you are trying to do, with a simple 3.5 to rca cable.
I have a Sony 46" LCD TV. I have a Direct TV HD converter box, a Sony Blu-Ray BDP-S360 Blu-Ray player, and a Pioneer DVD-Audio player connected to my Pioneer Elite Home Theater receiver. I have my Pioneer DVD-A player connected via Fiber-Optic cable. When i play a DVD or a DVD-A on my Pioneer DVD-A player, all of my speakers work fine, but when i play a dvd on my blu-ray player, all the speakers work except my subwoofer. How can I fix this problem?
What is happening is the the pioneer is set up so that you can choose how you listen to your DVDs. So first you must see how your DVD is connected via the audio. I am fairly sure that the Default on the Pioneer is to play it through the standard stereo if all you have plugged in is the left and right audio plugs. If you buy an optical cable or a plug in the Digital Coax out put to the pioneer receiver, then the pioneer will decode the sound and out put true surround sound. Some DVD players don't have a digital out put, but these are the cheapest ones out there. If yours doesn't have a digital out put, then you need to get one that does. They can be purchased for as little as 39.00.
Okay lets assume you bought a DVD player with Digital out put for audio and you have it connected to the receiver. Now, you have to change the mode on your pioneer to let it know that your audio is coming in DIgital when you select the DVD. (Though this may already be the case and you won't have to do anything once you connect it.)
Do you have your DVD player running through your receiver? You want the red and white (audio) cables to go from your DVD player to your receiver and the yellow (video) cable to go from your DVD player to your TV. Separate the red, white, and yellow cable into separate strands if you need to, but be careful not to tear the insulation. They should pull apart fairly easily. If I'm totally off or you're using a coaxial or component video/audio cables or a fiber optic cable, let me know. Hope this helps
