Question about amplifiers and my system....

New member Username: Punkbassist1989Post Number: 1 Registered: Jul-05 | ok so i just put in a brand new sound sytem of sony indash player and new speakers in my car. i was wondering if i should put 2, 2-channel amplifiersin-one for front and one for back, or one 4 channel amplifier. now basically it is a matter of if i use 2 amplifiers would i need another battery for the amplifiers because i also will put in another amplifier for 2 subs. thank you and hopefully you can help. |

If you tell us the specs of your new speakers we can advise you on an amp. If you have components up front, you also have the option of Bi-amping them, which means using a 4 channel amp just for the front speakers. Then you can get another 2 channel amp for the back speakers, or, if it were me, I'd just power them with the HU or not even use them. Also, you won't need a second battery. It will do you no good. What you need is a high output alternator if your car starts to show signs of sagging voltage rails. |

Silver Member Username: Alias747MN Post Number: 538 Registered: Apr-05 | Well.... Sony amps are complete junk. Stay away if you haven't already bought it. I personally wouldn't use anything made by Sony for car audio. |

Bronze Member Username: Punkbassist1989Post Number: 12 Registered: Jul-05 | well then what r ur recomendations for amps and or subs that are reasonably priced i dont want to spend more than 300 dollars for 1 amplifier |

New member Username: GhowardsClark, SD USA Post Number: 3 Registered: Jul-05 | hey I just started getting interested in sound systems and im kinda dumb at it so I appreciate any help and your patience. I am looking at buying 4 rockford fosgate 12'' stage 2 subs which run at 200rms and 400 peak will I be able to power them with a 1200 watt rockford fosgate 4 channel amp? I greatly appreciate any advise or feedback you guys have. Thanks |

Silver Member Username: ScubasteveAnnapolis, MD Post Number: 235 Registered: May-05 | garett, unless you have an electrical system than can handle the draw of a A/B 4 channel amp like the one you mentioned, you're better of with a Class D mono amp. It'll draw 20-30% less amperage for the amount of power it produces. |
|
Gold Member Username: GlasswolfWisteria, Lane USA Post Number: 8524 Registered: Dec-03 | if you want 4 subs, use a class D mono amp. not a 4 channel. it'll draw less current that way as noted above. get 2 ohm SVC subs, or 4 ohm DVC subs (same end result) if you want four subs on a 2 ohm stable mono amp @ 2 ohms final load. |

New member Username: GhowardsClark, SD USA Post Number: 5 Registered: Jul-05 | k like I said im pretty new so I do appreciate your help. They guy I bought it from said if I bridge it at 2 ohms I can get 2300 watts I dont know if that matters. Second thing is if my electrical system cant handle it, would a HO alternator be an option? what are some examples of a class D mono amp. The thing is I wasnt thinking real hard and already bought the amp, so what combination of subs would produce the best result? thanks a bunch guys I really appreciate it. |

Gold Member Username: GlasswolfWisteria, Lane USA Post Number: 8629 Registered: Dec-03 | give me the make and model of the amplifier. I'll tell you how much power it really has and what it can run. you want four twelves? |
|
New member Username: GhowardsClark, SD USA Post Number: 6 Registered: Jul-05 | which combination would be louder? four subs with the mono amp or four subs with a different combination. I have a pretty high budget so lemme know. Thanks |
|
New member Username: GhowardsClark, SD USA Post Number: 7 Registered: Jul-05 | the amp is a rockford fosgate punch p4004 1200 watt amp. I would like to get four twelves unless you dont think its worth it. Also I saw earlier you told jon stanton to use a 4 channel amp for his front and rear speakers. I am also planning on replacing my front and rear speakers so should I use that amp for the front and back and get a mono class D amp for the subs? |

Gold Member Username: GlasswolfWisteria, Lane USA Post Number: 8637 Registered: Dec-03 | use a 4 channel for components and a mono amp for subs. yes |
|
Sonnyboi Unregistered guest | i just bought 2 Kicker Solox 12's and i have a custom box. what type of amplifiers should i use and how many should i run to each sub? |
|
Gold Member Username: GlasswolfWisteria, Lane USA Post Number: 8689 Registered: Dec-03 | if you have a pair of dual 4 ohm coil subs, the Kicker SX1250.1 or KX1200.1 would be ideal |
|
Gold Member Username: GlasswolfWisteria, Lane USA Post Number: 8690 Registered: Dec-03 | oh you said Solo X I was thinking L7 what's the coil config on each sub? |
|
New member Username: GhowardsClark, SD USA Post Number: 10 Registered: Jul-05 | ok so if I do four 12's how big of a mono sub would I need or am i better of just doing two 12 inch subs and if I am how big of an amp should I use and also do you have any reccomendations for brands. Since I already have a rockford amp should I keep the same company or doesnt it really matter to mix and match |

Bronze Member Username: GhowardsClark, SD USA Post Number: 11 Registered: Jul-05 | The four 12's I am looking at are these: Punch STAGE 2 4 ohm 8" Component Subwoofer molded polypropylene woofer cone 60 oz magnet frequency response 20-200 Hz power range 50-150 watts RMS sensitivity 83 dB top-mount depth 3-13/16" sealed box volume 0.25 cubic feet ported box volume 0.65 cubic feet what would I need to power those? http://www.mmxpress.com/rock_subs.htm |
|
Bronze Member Username: GhowardsClark, SD USA Post Number: 12 Registered: Jul-05 | I know you guys are getting sick of me but I really appreciate it. Can I run four 12's with one mono sub or would I need like two 300x1 amps? |
|
Bronze Member Username: GhowardsClark, SD USA Post Number: 16 Registered: Jul-05 | what would I need to power four of these? Punch STAGE 2 4 ohm 12" Component Subwoofer molded polypropylene woofer cone 60 oz magnet frequency response 20-200 Hz power range 50-200 watts RMS sensitivity 86 dB top-mount depth 6.1" sealed box volume 0.85 cubic feet ported box volume 1.25 cubic feet |

Silver Member Username: ScubasteveAnnapolis, MD Post Number: 299 Registered: May-05 | Garett...I answered that question on the other tread where you asked the exact same question... https://www.ecoustics.com/electronics/forum/car-audio/151096.html Does that ring a bell? |
|
Bronze Member Username: GhowardsClark, SD USA Post Number: 19 Registered: Jul-05 | hey guys, class told me to get 4ohm DVC and get a 2 ohm stable amp, but steve told me that my wiring options are 1 ohm or 4 ohm and I was just wondering which one to do so I can get the right amp. Also does anyone have a link to the thread where glass explains how to figure out different wattage for different ohms and such? |

Gold Member Username: GlasswolfWisteria, Lane USA Post Number: 8763 Registered: Dec-03 | Garett, www.bcae1.com has sections for computing load for amplifiers based on the speaker impedances. it teaches you everything you need to know.. just take about a day to read the site.. you'll be amazed how much you learn there I know the author of that site, and he's done a terrific job of building the best site I know for learning all the basics of car audio and electronics. |
