car amp and sub for indoor use?
Hi, I have a sony xplode 800W amp with a 12" infinity sub, and I was
wondering if there is a semi-cheap way to hook it up in my home. What would be the safest way and what would i have to look out for? I would like to keep noise to a minimal level so that i can have a good listening environment but still have power going to the amp. Is there a way to convert the power from the wall 120v i belive to a 12v with the equivilant current to power my amp? I don't really want to worry about the battery dying and not having enough power, and i don't think having a car battery in my house to power the system is entirely safe anyways. any suggestions? please e-mail me at wackamack @ hotmail.com (not gmail, i only made that account to get here) |

I would use a dry cell battery and not a lead acid battery. price can be $150 and up depending on new or used and brand |

Hi - Been there, done that, and still working on it! I included two 12V computer fans powered by an old computer supply, so it's not silent, although on a gig there's plenty of crowd noise and LOUD music to mask the fan noise. 12V power is from a Pyramid PS-36KX unit, and although not capable of getting full power from the amp, there's enough clean loud sound to more than fill a 75' x 125' room, with 75 + people. They must have liked it - the party lasted til 4am!

Where did the math come from to get this?

You forgot to adjust your math for a sony 800 watt amp. 200 Watts x 1 @ 4 ohms
RMS or 400 Watts x 1 @ 2 ohms RMS. Why would he need a battery along with a power supply? In article , "e-nigma" wrote: "Captain Howdy" wrote in message ... Where did the math come from to get this? Ohms law P/E=I 800watts/14volts=57amps 800w/12v=67amps |

A battery is the best niose filter and Can handle the high current spikes that the power supply can not. |

What drivers are those? And is that an old school Infinity crossover? |

I have seen my share of sony amps and they are all rate in peak values, the
are lables in great big letters. Have you seen a Sony 800 watt rms amp, I haven't. A good DC power supply like the one that I have pointed out will be clean and also rated for surge output.. This is why I was wondering why you had a battery in the mix. My math was from info provided. How do you know that amp is putting out that wattage with the info provided? A battery is the best niose filter and Can handle the high current spikes that the power supply can not. |

wrote in message oups.com... Nice. What drivers are those? And is that an old school Infinity crossover? Thanks. The drivers are 'Logic' brand. http://www.logicsoundlab.com/CLX12.html http://www.logicsoundlab.com/ZX620.html The controls you see are for tweeter & mid levels, and a tweeter fuse. They came from an old (1979) pair of Infinity RSM's: http://www.flickr.com/photos/joearnold/160902701/ http://www.bobbyshred.com/infinity/RSM.html In the above pics, the original EMIT tweeters and 12" woofers are long gone, and the enclosures were in rough shape, hence the new boxes. The original Infinity X-overs (modded) are now being used. This project has been a TRIP! Thanks to the great folks in this group, it's also been a great learning experience. Joe Arnold |

car amp and sub for indoor use?
wow... didn't expect to get this many replies this quickly and this
helpful... so thanks already! one question that still remains, would i hook up a battery and a a PSU or just the battery or just the PSU etc? I was hoping that i could take out the battery and use just the PSU but i couldn't find any under $150 that did what i needed. Or do i have to meet the recommentded power for the amp before doing damage to it? I have decided to test it in something like my room, so i would want something that wouldn't kill me, i got the dry cell battery suggestion for that. other questions i have a how long wound i be able to play music with? is it worth the money or should i just get a computer system with a 10" sub? (put me out of my way about $400 but whatever, i want better sound than this crappy 2 speaker stereo i got) I found that PSU that you were talking about on Ebay, the PYRAMID PHASE III 12V-15V 35AMP REGULATED POWER SUPPLY. (copy and pasted from e-bay) do you think that would power my sub amp? i found a few sites that i think have good spec info on my amp, i will post a few, some are american. i don't think it should matter. http://www.hookedontronics.com/show_...ony_XM-1252GTR http://www.crutchfield.com/S-WW4sseI...20&I=158XM1252 http://www.bestbuy.ca/catalog/prodde...gon=&langid=EN thanks for all the help guys, you are awsome |

IMO Purchasing a 120v/ac plate amp for that sub would be cheaper and easier. -- -Cyrus I totally agree. This question has popped up time and time again for over a decade on RAC. Unfortunately, technology has not changed the answer much. It is just plain expensive to convert 120 volt AC to 12 volt DC WITH SUFFICIENT AMPERAGE to power a car audio amplifier (ESPECIALLY a subwoofer system with it's characteristically high peak current demands). I looked into this once MANY years ago (17, to be exact) as I had an extra HU and amps lying around and wanted to build a system for my garage. Frankly, not much has changed since then when it comes to the cost of large transformers which are needed to accomplish this. In almost every case, you are better off buying an amp designed for home use. Lots of folks try to sell their older two channel gear as they upgrade to multi-channel home-theater amplifiers. Ebay is great place to look for used two channel amps. You can find some really good deals on two channel amps from respectable brands like Adcom, Denon and Yamaha. However, if you plan to use the system for only short periods of time (like no more than an hour), then I suppose a relatively low cost option might be a car battery connected to some type of car battery charger (someone has already suggested this I believe). The amps could get all the current they need from the battery and when the system was not in use the battery could recharge. Frankly, though, this is kind of hokey, IMHO. MOSFET |

another question... if i get a plate amp... could i get another sub...
i was thinkin of gettin my friend to buy the infinity and i could go grab a 12" explode... would the plate amp be able to power the car sub? any conflicts? thanks... Randy |

car amp and sub for indoor use?
final question, don't know if i asked this already, would it be safe to
have the battery hooked up to the charger while it is playing? or is that ill advised? just wondering if i could get a couple more hours out of it if it was charging at the same time withought burning out the charger... Randy aright well i am only going to be using the system for a bit at a time... probably some showing off involved and you guys will definately be mentioned. thanks guys for all the help. i think i got all the help i needed and am ready to undertake the remainder of the project. tanks for all the help guys... and MOSFET... you are on this forum way to much... lol joking ur help was great along with everyone elses. happy listening and wish me luck... |

LOL My wife tells me this sometimes, too. It should be OK to use the charger while drawing current. I can't see where that would cause any problems. MOSFET |
