[QUOTE="n2audio, post: 8194355, member: 540940"] From something really low to something slightly higher, but still really low. There's a little bit of a gray area. If you look at a thd vs output chart you generally see thd going down as power goes up - UNTIL the amp's power supply gets stretched out -- then it shoots from ~0.1% to 1% where the measurement is taken. There are some old amp reviews on carsound.com's old review pages that show a lot of really good test charts, and they all follow roughly the same pattern. The Kenwood KAC-929 for example - 460w rms -- has THD measurements of 0.05% at 2w steadily decreasing to 0.01% at 400w, then jumping up to right about 0.10% at 500w and about 530 or so at 1%. All things considered -- if you're pushing an amp to its limit (clipping) you're going to get distortion, if you dont, you won't -- bridged or not. [/QUOTE]
