help please Unregistered guest | well the certificate that came with the amp reads exactly this... 226 RMS Watts per channel @ 4 ohms < 1% THD+N 723 Total RMS Watts @ 2 ohms <1% THD+N (all channels combined) 983 Total RMS Watts @ 1 ohm <1% THD+N (another guy i saw had the same amp and his was 1080 watts...so i guess its not abnormal or something...) From what i read on the adire site a few months ago they recomended like a 600-900 watt amp for the enclosure i have...so its alright i think... and the guy who i bought the amp from thought the same...so i think it'l be plenty of power... |

help please Unregistered guest | and yes the certificate says the right amp...and the exact serial number thats on the back of the amp... |

You should look into another amp if you can. It's almost like your wasting its potential. One of the voice coils alone could take that power. |

help please Unregistered guest | yea...i think im gona go and take the amp back now...i have thought about it all day...i know the guy who works at the shop and ill exchange it...what are yur suggestions...i think i want to stay with the rockford power amp series...he has a mono block that puts out 1000rms @ 1 ohm...should i take that instead...and if the amp is underated it should put out around 1200rms roughly...so is that enough for the brahma??? |

Bronze Member Username: Riebread77Post Number: 54 Registered: Jun-05 | i'd go with the rockford t20001bd amplifier...It'll put out the 1000+ watts rms at 1 ohm (2000 max)...the actual power will be more like 2200 on the birth sheet. rockford power series is no joke. It will slam. adjustable bass boost is nice touch to legendary power series. Rockford power series is noted for their highest watt/size ratio. If you have the cash. Go with that amp. Look on ebay for cheaper if you can't afford to buy it from a shop. |

help please Unregistered guest | i looked at the specs on that amp...and that thing puts out 2000 rms...i really don't think im gona need that much power...did u mean for me to look at the 1000 rms one...the t10001bd puts out 1000 rms @ 1 ohm...and probly a little extra...maybe lookin more towards 1200-1300 rms...i think that is plenty of power for a single brahma...and its more in my price range...the 2000 watt model is over 750 bucks on ebay...im lookin to stay under 500 or just about 500...thanks for all yur suggestions...im goin with the t10001bd amp... |
