[QUOTE="grampi, post: 3689921, member: 544496"] I don't get it. My HU is an Alpine 9887 with 4V preouts. My amp is a Kicker KX 600.4. I'm running it in 3 channel mode with 75wrms going to my comps and a bridged 300wrms going to my sub, an ED e12k in a 1.25 c.f. sealed enclosure. I have amp #1 (which is the amp for the comps) gain set right at half and they get more than plenty of signal. However, I have to have amp #2 gain all the way up AND the amp's bass boost all the way up to even get a decent amount of sub output (and I'm not basshead by any means, I just like to feel my bass as well as hear it). What's wrong with this picture? I'm running doulbe the power on my sub as I'm running on my comps, and yet the sub output is the one I have to crank the gains on. Makes no sense. The sub sounds clean even with everything cranked up (no distortion at all) so it doesn't seem like the amp is running out of power. It acts more like it isn't getting enough of an input signal from the HU. I would think if I was overdriving the amp I would hear indications of clipping. I suppose I could try a line driver on the preouts to the sub, but a lot people have said to stay away from line drivers. That would however be a lot less expensive than the alternative which would be to bridge my entire amp for 600wrms, but then I'd have to buy a sub that could handle that much power, and I'd have to buy another amp to drive my comps.
