[QUOTE="helotaxi, post: 2264915, member: 550915"] AudioControl makes it. Processors that boost voltage are not additive. The output of any processor is simply a low current amplifier, and just like a power amp, you can clip the processor by overdriving the output. Most every large format EQ that I know of will act as a line driver as well. Adding another line driver will only add to the noise floor and increase the chance of inducing ground loop noise. I used to have a setup similar to what you are suggesting. It consisted of an Orion half-DIN preamp with a master volume, sub-crossover and level control and a 3 band parametric EQ. From there the high freq signals went to a pair of AudioControl EQT 31 band EQ and then on to the mid/high amps. The idea behind all this was 1) to get a sub crossover and level control (this was over 10 years ago when remote gains and built in crossovers were not at all common, especially in competition amps) and 2) provide a set of tone controls that could let me screw around a bit but be set to 0 and the system EQs could do their job for serious listening. In the end the only one that really mattered was the first one. All an indash EQ is is an overglorified set of tone controls not a serious EQ. I never messed with the EQ portion. Unless you are a person that messes with the treble and bass control on your HU all the time, don't bother with an indash EQ. [/QUOTE]
