FINALLY CAR AUDIO IN HOME

 

Unregistered guest
So finally by the end of the month i should have my brand new DUAL 340 watt amplifier being powered by my power supplies in parallel, i will try and get a camera so i can some pics, im gonna definately wanna get a can of air, so i can spray out all of the power supplies, and im actually thinking about mounting them on something nice, and actually taking all the stickers off, and writing with a marker all the info on the inside (ie: the voltage at what currents) and actually maybe painting them all black or chameleon from autozone, and i wanna go get 4 of the blue 3.5mm fans and replace the stock fans with blue lighted fans. i'll keep you guys updated, its gonna be nice damn guys..

Don't know yet exactly what i wanna use for the subs, because i have one good kenwood tornado, and one bad one, i can either have 340 watts max going to one kenwood tornado, or get two cheap ace subs from best buy or wally world. best buy has two ten inch dual subs for like 65 bux, i dunno what do you guys think i should do? my limit is like 35 per sub i dont wanna spend alot.

What kind of power supplies are you using? (I'm assuming you are using computer power supplies) What's the current ratings for the +12V output?
Also, looking at the specs for the amp:
70 Watts RMS x 2 (4 ohms)
30 Watts RMS x 2 (2 ohms)
200 Watts RMS x 1 (4 ohms)
I'd suggest going with the single tornado sub, assuming it has a single voice coil at 4 ohms. that will give you the most power out of it.

This is not exactly an audio question, I know - but I have read many posts which discuss the principles used in powering PC hardware, used to power car amps in domestic aplications - with good results, too.

I need to place a small, reasonably efficient, and quiet running cooling fan to the top of the motor unit on the air compressor in my art studio. I'm thinking that I can use good parts out of a scrap computer, but would like advice on how to hook this up and whether indeed it will work, without the motherboad in between power and fans.

To give an idea of the size and area to be kept cool, the motor unit is basically a fridge motor in principle and is exactly the same size. It does not run constantly - as the the tank reaches pressure, it has an suto cut-out, so is not expected to reach particularly high temperatures.

Sorry to post twice, but it appears my other post has become lost in the haystack of audio postings.

Thanks in anticipation,

V

well varney i know little about what you are doing, but i would try to find a fan that will be the right size, and what i would do is just wire it into the power on for the fridge motor, that way when the motor turns on so does the fan, but this is not a post for arts and fans and studios and nonsense..this is for my car amp stuff in my room jeesh
but yea i will be powering the amp with a total current of about 36A at 12V and what kinda sux is i have been workin on this for quite sometime now, and i think i will finish it just so i can say i completed it, but afterwards, im debating, i might try and sell it, and just buy a single powersupply that puts out 34A of current, im not too worried, i dunno maybe it would be just better to stick with the one immaking, cuz it has more current, and the power is divide amongst four PSU's

A car audio sub is going to sound horrible in a house. Car audio subs are designed with cabin gain in mind. The average car sub has an Fs of around 30 hrtz while a home audio sub is centered around 20 hrtz. A car sub will allow for no low bass extension. U would have to buy a graphic equalizer to force the sub into an acceptable frequency response curve. Save up and buy an Adire shive or comparable subwoofer from parts exspress. u will be much more pleased.

adire shive? i didnt find anything on partsexpress called an adire shive subwoofer

He meant Adire Shiva. PartsExpress doesnt sell Shiva's anyway. So either way you wont find them on that site. Nick said an Adire Shiva OR(keyword) a compairable sub from parts express..

I wont to run my 2 amps in my bedroom. I have a Pioneer GM-X862 760W amp with 2 25 amp fuses. And a Pioneer GM-X262 200W amp with a 20 amp fuse. Where can I get a converter that will power these amps, and how much will it cost?

Thanks!

It's funny, everybody here seems to want to put car audio in their house, and the design emphasis of nearly every high end speaker and sub manufacturer is to bring the quality of home audio to the car.
 

Unregistered guest
derk...too big of an amp, your not gonna wanna run the 760 the max you are gunna wanna use for a amp is something under 35Amps. and you can buy a powersupply from newegg.com that will provide enough current for it

I can't find them on newegg. Could you give me the URL. Say they were 35 amps max, could you wire two power converters together to make 70 amps max?

i dont know anything about power converters, the power supply i was checkin out on new egg was a 34a psu i think not 35a the link is ..

12V@34A PSU's

(the very first one is 50 bux rosewill psu)

12V@36A PSU's

http://www.newegg.com/app/ViewProduct.asp?submit=property&DEPA=0


AND WARNING-------- i would be very concerned, you can try hooking two 35amp psu's in parallel, you will need Diodes, to prevent current seeping into eachother, and you will also want to be weary of your wattage of your lines in your house, most power lines are connected to a 15amp circuit breaker, and when you have 120vac@15a you have a total ofabout 1800watts i believe so take your 12v@70 P=V*I, so 840 watts is right there, plus whatever else you have hooked up in your room be very careful, also with old houses and old wiring.

12V@36A PSU

ALSO NOTE-what i did was i tore apart the power supplies i had at home joined them together for a total of 36A, this is now for sale if you would like to buy it you can email me, but im just gonna buy a single psu from here on out, plus i saved you the work of modding the psu's to make them applicable for your amp. if you want me to help you you can email me.

Thanks for the advice, but all three of those links are the same broken link. Could you post the right links.


Thanks.
