Bronze Member Username: Wrjh12Post Number: 15 Registered: Jul-06 | Heading:Profile AP1000M, Has More Watts RMS Than ALPINE MRP-M450 BUT COST LESS WHY?... I Have Recently Purchased Two Alpine S's. And I was comparing Amps throughly. And I saw that the Profile AP100M has 310 RMS and cost 159.99 on Crutchfield. Then I came Across The Alpine MRP-M450 its wattage is 220 RMS but cost 199.99. I want to buy one of the two. Whats weird is the price diffirence why isent the profile more expensive than the Alpine? and what would you get if you had to choose one of the two Profile link: http://www.crutchfield.com/cgi-bin/ProdView.asp?i=489AP1000M Alpine link: http://www.crutchfield.com/cgi-bin/ProdView.asp?g=120&I=500MRPM450 |

Bronze Member Username: Wrjh12Post Number: 17 Registered: Jul-06 | Chauncey your right but wouldent you go with more watts like the profile, or what would you go with out of thoes 2 |

Bronze Member Username: Wrjh12Post Number: 18 Registered: Jul-06 | Oh, well have you checked the Profile at all? |

Gold Member Username: IlluminatorUSA Post Number: 3772 Registered: Apr-05 | A watt is a watt yes, but that's only when the amp is being driven within its limits. When you start to drive it into clipping (which can happen at even normal volume levels), then a watt isn't a watt anymore. The best example are tube amps vs. solid states. Everyone agrees tube amps sound warmer when they go into distortion whereas solid state have a really harsh sound. But when both are in their limits, they sound the same. The same can be applied to different solid state amps-it's all how well the power supply and output transistors are built plus other pieces of the circuit. In essence, a watt isn't a watt when an amp is driven to clipping, and that's where high quality amps generally will sound better. And I agree that build quality/durability/reliability of an amp is definitely something that high quality amps have more of. |

Bronze Member Username: Wrjh12Post Number: 19 Registered: Jul-06 | Wow Jexx, you pretty much sumed all of it up for me. Yea i think i might go with the Alpine, but check my new thread im going to put up. Its about a Infinity Amp. Thanks again all and Jexx, yall are big helps |

Silver Member Username: N2audioLawrence, Ks USA Post Number: 936 Registered: Mar-04 | Clipping shouldn't be part of the decision. All you have to do is set your gain correctly and clipping will be avoided altogether. Another issue to consider between these two amps... Profile is a good budget amp, but it wouldn't be going out on a limb to say it may not produce the power it's rated for. Being rated for 500w at 2 ohms it may only produce 400-450. While Alpine is notoriously under-rated. The m450 is rated at 400w at 2 ohms, but probably produces 450-500. So with Alpine you'd be getting a better name, higher perceived quality, more efficiency, and about the same power. |

According to Rockford Fosgate, that isn't the case:

Gold Member Username: JuliobSanto DomingoDominican Re... Post Number: 1610 Registered: Dec-05 | the key is to control the gain |
|
Gold Member Username: IlluminatorUSA Post Number: 3783 Registered: Apr-05 | Well you can look all over the net and find articles about amps clipping during moderate listening levels, but if you want to completely eliminate clipping via the gain, you'll loose top end volume, and that's certainly undesirable for almost anyone to do... |

Silver Member Username: N2audioLawrence, Ks USA Post Number: 938 Registered: Mar-04 | I think RF is making a broad assumption that the average consumer doesn't know what a gain is for. For the majority of people that return blown coils that may be true, but not everyone. Besides - if the way an amp clips is part of the decision making process I would think you have bigger problems. |
