[QUOTE="n2audio, post: 4061594, member: 540940"] IMO LD's became obsolete several years ago. Now that 2v is standard voltage for even the cheapest of HU's and about every amp's sensitivy range goes to 1/4v or less any HU/amp combo should allow the amp to reach its optimal level of power w/o bringing audible noise into the equation. Hopefully the LD's adjustable - unless you want your system output to go from zero to maximum in a fraction of your HU's volume range you'll have to limit the LD to around 5v when your HU's at full (unclipped) volume. W/O your LD you probably wouldn't have needed more than 1/2 gain. My HU is 2v, my amps will accept up to 7v. I set my gains for rated power (they're under-rated amps) using the DMM method, and both gains are less than 1/2. [/QUOTE]
