Hello, Im new here, I have a question that has prolly been asked a million times but here it is anyways, I have a 1999 Tahoe z71 and I just bought two 12" Type R's last night, and I need to find the right mono amp to power these, I currently have a new Alpine MRP-M850
Mono subwoofer amplifier. I dont believe this will be enough power to run both 12's can you guys give me some imput on a proper amp that will push these subs in a sealed or ported box.
Thanks Chris |

what are the vc of the subs? depending on that you'll want to look for an amp that'll do about 1200-1600wrms at the load you need. |

Someone suggested that I might look into a 2 channel amp instead of a mono amp, oh by the way I just returned the Alpine MRP-M850 back to the store, seeing that this amp will not be sufficient to run both subs. |

He's got the dual 4 ohm subs, and that's not a 1ohm stable amp. |

it is a two channel amp...look at the pics. it has two channels and it will put out about 1100 watts rms at both four ohm and at two ohm
http://www.crutchfield.com/S-iNCiQPanKDV/cgi-bin/ProdView.asp?g=120&tab=morephot os&pi=1&i=500PDX1100&display=L#Tab follow that link..it shows two channels on the amp
With my setup i have each sub wired to each channel and it pushes them just fine |

Im back home from work now, ok theres some good imput here, I will prolly run both subs @ 2 ohm because finding a amp that runs stable at 1 ohm is difficult to find, the subs normally are dual voice at 4 ohm. Im trying to get the most out of these subs with out frying an amp. So is a 2 channel amp out of the question?, and I guess what i need is to find a amp that will run
1000-1500 rms per sub.
Thanks |

that is alot of power to put to each sub...with that much power it is alot easier to blow your speakers...for that kinda power i would say Hifonics... just my opinion |

Is that per sub or does that get broken down to 500 rms after you bridge to 2 ohms? Im still learning the lingo here sorry.. |

What Corey and me described is only one channel...so that would be for only one sub...but both of those amps go down to 1 ohm. so you could wire your subs to get the max out of either of those amps.
The amp Corey said about will put out 1600watts rms @ 1 ohm...800 for each speaker
The amp i described will put out 2000 watts rms @ 1 ohm...1000 watts for each speaker |

If the information is correct below from crutchfield, then the actual rms to 2 subs @ 2 ohm would be 500 rms per sub
Details:
» mono subwoofer amplifier
» 1,000 watts RMS x 1 at 4 ohms
(1,000 watts RMS x 1 at 2 ohms) |

I guess running at 2ohm it would be cooler on the amp instead of running it at 1 ohm each, is either one of those amps you mentioned run stable at 1 ohm? |

long thread
but simply
if u have 2 dual 4ohms subs then get a good amp that does about 1200wrms @ 1 ohm
if ur subs r dual 2 then 1200wrms @ 2ohms
those type Rs will handle 600 each comfortably
though u can use a 2 chan amp - a monoblock is prefered for subs .... |

That's not a 2 channel amp, nor is it a 2000 watt amp. It's 1000W. And it's not a 1 ohm stable amp. It'd still work for him because it'll still do 1000 watts at 4 ohms, but if you wired that thing at 1 ohm you're just gonna burn it up. And having 2 speaker outputs doesn't make it a 2 channel amp. It says right on it that it's a mono amp, the two outputs would just be parallel connections. And even if it was a 2 channel, you'd bridge it anyways with subs. Unless you were a dufus and ran your subs in stereo

Man im getting some good ideas here, thanks to you guys, its been a long time since I was into car stereos actually its been since 1985 since I had my last stereo competition, I placed 1st in the loudness category hitting 148.1db in a 1982 camaro, but that was along time ago! things have changed so much in design and competition, Im married now for 16 years and 3 kids later, and I have found new love again for my stereo (I know that sounds silly for a 42 year old), but, this is just another way to keep holding on to my youth..lol.
Thanks again everyone for the superb advice !!! |
