[QUOTE="02WS6, post: 8692023, member: 678581"] Yes, especially at this price point. There are so many variables that can go into this, its really really difficult to point you in the right direction. First, you linked the RZ5--2500D which is the 5 channel amp instead of the RZ1-2500D which is the Mono subwoofer amp. Which one specifically do you have and how do you have it wired? 2 or 4 Ohm? Second, what Head Unit are you running and what pre-out voltages does it provide? 2V or 5V? Third, what car/alternator/gauge wire do you have going to the Amp? (Provides an understanding of the quality of signal going to amplifier and electrical headroom to support the amplifier draw) Fourth, what type of box are you using? Sealed/Ported/Cu.Ft? You're most likely not going to be able to overdrive that Subwoofer based on wattage alone, the sub is rated at 1200 RMS vs the 600-650 RMS that either the RZ5 or RZ1 amplifier can produce. The most likely scenario at this price point is you'll cause the Amp to "clip" where the amp reaches maximum output capacity but keeps on trying to keep up with the gain ratio set, to do this it will cut the waveform which is identified as clipping. When an amp starts clipping an output signal all kinds crap can occur - Overheating, mechanical failure, protection mode etc. In a perfect world, you're giving the Amp 4/5V preouts, with clean power, turn off all EQ/Bass Boost and measure a 40/50hz signal with a DSO Nano. Set gain based off of a clean sine wave. Gain level changes depending on all of the other conditions mentioned. Less optimal way of verifying is using a multimeter to measure VAC output to RMS rating. (V²/R=Wattage) Once you know your gain is set properly/not clipping then you make sure your sub box matches the recommended enclosure specs, this protects the sub from reaching mechanical limits and maximizes the sound it can produce.
