New member Username: YungndumbScottsdale, AZ Post Number: 1 Registered: May-10 | below are a couple of links of amps I am currently considering. I am trying to power 2 12" 4ohm DVC Boston Acoustic G3's. I want a great SQ amp that will complement the SQ capabilities of these subs. I'm familiar with Rockford Fosgate and US amps, but which amp out these would sound the best? DLS RA 10 http://www.woofersetc.com/index.cfm?fuseaction=product.display&product_id=7131 Rockford Fosgate T1500-1bd http://www.amazon.com/Rockford-Fosgate-Power-T1500-1bd-Amplifier/dp/B000NI865A US Amps MD-1D http://www.woofersetc.com/p5360/MD1D--US-Amps-1-Ch-MD-Series-Amplifier.htm Zapco REF750.2 http://www.woofersetc.com/p601/REF7502--Zapco-Reference-2-Ch-750-Watt-Amplifier. htm personally RF is at the bottom of my list, but let me know |

To achieve the best sound from your substage, install and enclosure would be what I focused my SQ questions towards.. In my personal opinion I would look for a class AB amp over a class D amp for a more SQ orientated setup. |

One site showed the RF 1500 doing 750 x 1 at 4 ohm, the link you have doesn't though, so I'm not sure what's up with that. |

Remember in car subs you really can't audibly hear distortion below about 10% anyway, so what you really want is to just find a good amplifier with a decent damping factor and slew rate, and the power and reliability you desire. Reliability and RMS power are waht you pay for with an amp. SQ isn't really about the amp, that's about the speakers. Richard Clark put forth that you can't hear the difference between ANY two amplifiers with the same power output, operating within their parameters (no clipping etc) and nobody yet has been able to objectively disprove this, else he'd have paid out a very large sum of money to the person who could. The main reason I personally use a class AB amp for my sub, and another of the same amp for my front stage, is simply because I have the amplifiers already, and they are extremely well-made amplifiers. I have no reason to replace them as of now except for the possibility of replacing my 2 channel front stage amp to put in 6 separate channels to drive the fronts so I can use an active filter network to optimize time alignment and crossovers. |
