New member Username: ObamaSanDiego, California United States Post Number: 1 Registered: Aug-11 | Hey, guys, im a bit new to subs and amplifiers so i'll need a bit of help. To start off I have a Honda Accord 1998 ex with 2 Rockford Fosgate p3 400W(ea) subs that I got for free. The guy that gave them to me instructed me to get a 2 channel amp with 750-1000 watts to power both subs. I have all the wiring and hes putting in a stereo system aswell. So basically my question is, whats a good brand amp for my particular subs? I would assume since my subs aren't that powerful and my cars not that great that they wouldn't require high end amps. Any suggestions? |

If you wouldn't mind, could you explain how a monoblock amp should be wired up to power 2 subs?? |

Gold Member Username: KaerfplSpencerport, NY USA Post Number: 1289 Registered: Jun-06 | LOL at Glasswolf But putting that asside, Glasswolf is correct. You do not want a 2-channel Amplifier, you want a Mono-Block (1-channel) Amplifier. Glasswolf already beat me to the punch suggesting the AQ1200D. Here is the website to where you can purchase one: http://www.audioque.com/AQ1200D-Amplifier_p_30.html Here is the link to the other Amplifier that Glasswolf suggested: Hifonics Brutus BRZ1200.1D: http://www.sonicelectronix.com/item_23548_Hifonics-Brutus-BRZ1200.1D.html There are other Amplifiers out there that will also give you the power you need, but these two here is your best bang for your buck. Plenty of power, and both under $300. If online shopping is not an option for you and you need to shop local, then what you are looking for is an Amplifier that can at least supply 800 Watts RMS at 1 Ohm. Also, below is a link of a picture on how you would need to wire your DVC 4 Ohm Rockford Fosgate P3's to achieve a 1 Ohm load: http://images.the12volt.com/12voltimages/2_4ohm_dvc_1ohm.gif |

Gold Member Username: KaerfplSpencerport, NY USA Post Number: 1294 Registered: Jun-06 | The only way to assure that you will not have these problems is to perform the "Big 3" upgrade. Details of this can be found by clicking on the link below: http://www.the12volt.com/installbay/forum_posts.asp~TID~73496~PN~1 The stock Alternator in your 1998 Honda Accord EX is 80 Amps. Typically, this would be fine with an Audio System of roughly 1000 Watts RMS however, we are unsure of the condition on your current Alternator. Odds are that in one point in time, the Alternator is going to fail because of this extra draw and stress from the Amplifier. It could take a few weeks, months, or maybe a year. Overall, I would say play it safe, and upgrade the Alternator before you are presented with a domino effect of electrical issues. Either that, or just make sure to have a few hundred dollars on the side to use on a new Alternator in case your current one does fail shortly after installing everything. Better to play it safe that sorry I always say. |

Platinum Member Username: GlasswolfColumbia, South Carolina Post Number: 14460 Registered: Dec-03 | yup, coils in parallel, subs in parallel.. 1 ohm load. then you go with an amp that's 1200W @ 1 ohm. class D mono amps are the most efficient, but are typically only for subs, which is why I suggested that route. As for having enough of a charging system.. just put the stereo in, and if you do have problems, or voltages drop below 12V, you'll want to give thought to a larger alternator, or keep the volume below the point you have problems. simple as that. |

New member Username: ObamaSanDiego, California United States Post Number: 8 Registered: Aug-11 | Thanks. My friend gave me his HIFONICS HFi1000D 1000 W Car Mono Class D Amplifier. Would that work out alright?? |

Silver Member Username: Joe1234Post Number: 196 Registered: May-09 | The HIFONICS HFi1000D is 1 ohm stable so it will do just as well for wiring all parallel. Also it won't be able to stress your electrical system as much as a 1200W amp. |

Gold Member Username: KaerfplSpencerport, NY USA Post Number: 1305 Registered: Jun-06 | Just as Joe Durkham stated, the Hifonics HFi1000D will be able to supply enough power to your P3's, so it is an Amplifier that you can use. I would however just to make you aware that this specific Amplfiier is not true to it's specs.Unlike the Hifonics Brutus BRZ1200.1D, the Hifonics HFi1000D is not CEA-2006 Compliant. The true output specs at 1 Ohm is going to be anywhere from 650-850 Watts RMS however, this is still enough to power both your P3's. In all honesty, I would use that Amplifier as a crutch to enable you to save up enough money to purchase either the Hifonics Brutus BRZ1200.1D, Audioque AQ1200D, or any other Amplifier that is CEA-2006 Compliant and supports the minimum of 800 Watts RMS at a 1 Ohm load. |
