If you dont want it effect all speakers then get a sound processor with the flexability to tune each speaker individually.

it is a full signal. This means that from 20hz to 20khm the signal is not crossed-over.

The adjustments you make at the headunit with bass and treble will change the sound. But most aftermarkets headunits do this too.

The sound is not altered at higher volumes either. This happens in the bose amp.

My DM801 has a rta and i could see the full range signal coming just fine when you have bass, mid and treble at 0.

The biggest draw back of the stock bose HU is the voltage output. Its only like 500-700mv. Not that great. Most aftermarket systems are at a minimum of 4 volts these days.

Thank you very much. I just wanted to make sure I was really getting the full frequency since I am going to use the same signal for my sub.

Mine is ok without the line driver, I just turned the gain up a tiny bit on the amp. If I got a line driver, would I be able to keep the gain at 0? Would it give me a slightly cleaner sound? Right now I don't hear any noise from it... just wondering if I should buy a line driver or not. A processor would be nice so I could set the timing on the speakers though.

EDIT!!!!: Last night I may have been a little excited to test my new components and amp. Today I was driving and I did notice a very quiet whine with the engine. I could only hear it when no music was playing. So I am ordering a line driver now to get rid of the problem. I don't want any noise at all.

Edit 2: I thought of one more thing. If the signal is going from the factory HU to the factory amp and there is zero noise, where is the noise being introduced when I add an amp? I added a 1 foot RCA cable to the factory wiring from the HU. Is that where the noise is coming in? Why doesn't the factory unit have any noise with that long wiring and low voltage? And the factory wiring is bundled together with the power wire for the amp, but no noise...
