[QUOTE="n2audio, post: 8041310, member: 540940"] I think Zako is having trouble reading that chart. That particular amp is at 0.02% THD at 200, and jumps ALL THE WAY UP to about 0.06% at 400w!! (yes, that's sarcasm) 0.06% thd is still more than 10x less than what is generally considered to be the audible threshold of distortion (1%). I'm all for head room, but this example is irrelevant. Yes, distortion tends to increase as an amp reaches its power limit, but any amp that's even reasonably good quality will meet its power spec with no signs of stress -- certainly nothing audible. All you need is a basic 2 ch amp that bridges to 200-250w rms at 4 ohms. They are everywhere. There are probably hundreds that would work well. A really nice amp: [URL="http://www.sonicelectronix.com/item_37929_Image-Dynamics-i2300.html"]Image Dynamics i2300 2-Channel Class AB i Series Car Amplifier[/URL] GOOD amp: [URL="http://www.sonicelectronix.com/item_9853_Rockford-Fosgate-Punch-P200-2.html"]Rockford Fosgate P200-2 Punch Series Compact 2-Channel Amplifier[/URL] [URL="http://www.sonicelectronix.com/item_39680_Cerwin-Vega-VEGA250.2.html"]Cerwin-Vega VEGA250.2 (Vega 250.2) Class AB 2-Channel Car Amplifier[/URL] Cheap but effective: [URL="http://www.sonicelectronix.com/item_23656_Precision-Power-PPI-S200.2.html"]Precision Power PPI S200.2 (S2002) 2-Channel Car Amplifier/Amp[/URL] The clarion you linked would be a HUUUUGE amp for your sub. With a 2 ch amp you'd want to bridge it to eliminate left/right issues -- at 4 ohms bridged that amp is capable of around 600w rms. I think you might have overpowering issues at higher volume even with the amp turned all the way down. I'm curious about your HU. The only HU I know of that will do more than 20-22w rms per channel would be an alpine with the power pack. [/QUOTE]
