Q: How many channels does this amplifier have?
A: This KICKER amplifier has a 4-channel output, allowing for system expansion.
Q: Can the dsp/eq be adjusted ?
A: The other answers are a little too cut-and-dry. The answer to this question is a bit more nuanced. You can adjust various aspects of this amplifier, but other things cannot be adjusted. Let's say you just installed it in your car. The first thing you'll do is run the auto-program. First you'll download the pink-noise test tones from the Kicker website and load the track onto a USB drive (you can use Bluetooth also, but it's preferable to run it from an offline source). Then, you take the included microphone and place it on top of your driver's seat headrest, facing directly towards the sky. Next, you plug the mic cable into the 3.5mm jack on the amplifier. Play the audio track on your radio at a reasonably high volume (doesn't have to be maxed out, or at 3/4 volume, just reasonably loud). Once the pink noise is playing through your speakers, press the button on the mic cable, and it will start the countdown, during which time you'll close all your doors and step away from the vehicle while the programming runs. This takes maybe 2-3 minutes to complete. During that time, the amp will chop and screw the pink noise test tone, and calibrate the time alignment and EQ of each of the four channels. It'll make chirps and sweeps and lots of strange noises. You'll want to remain as quiet as possible during this time, and pray that nobody honks their horn or calls an ambulance during the programming window, because it'll screw up the program and you'll need to run through it again. Let's assume everything goes great, and you get the "success" tone at the end. this means that the on-board DSP has been programmed, and the time alignment and EQ are set. Now to your question. You cannot go in and adjust the DSP or EQ settings. But, you can turn off the DSP, you can turn off the EQ, you can use the DIP switches to set the amplifier's high-pass crossover points, and you can enable compression and limiting--all this on top of the normal gain setting. Personally, I turn the compressor "on" and I ended up turning "off" the DSP while keeping the Kicker EQ enabled. I have the crossovers all turned off. This, to me, sounds better than the alternatives. So you cannot adjust the EQ and DSP as they are set by the amplifier during the auto programming. But I don't think you'd really want to, anyway. If you want full control over DSP and time alignment, you would want to get a separate DSP unit that you can adjust yourself. The Kicker amp is pretty awesome. I own several other 4-channel amps but none have managed to replace this one in my car. The Auto EQ in particular helps backfill for what my stock headunit cannot provide. I'd love to replace my headunit but the layout of my dash makes it extremely expensive and complicated to replace the factory equipment. I strongly recomment this amp. You won't want to mess with the DSP or EQ settings anyway once you hear the results. It's really good. I only wish it was more powerful, but it defintiely gets loud. I never run music at more than ~40-50% of max volume, it gets really loud. I just feel like it lacks that power to drive the speakers like they're meant to be driven. Good luck.
Q: I bought this amp. My question is. Do I also need a amp install kit? Thanks
A: Yes, you will need to run power and ground cables with an inline fuse to install this amp. The amp does include RCA wires

Great 4 channel DSP
Great sound if you want to add more power to your stock head unit. It may be a little complicated to install but its worth it!

DSP is very good once you get it working.
Pros: Small. More powerful than you expect. Auto-EQ and DSP are impressive if you are integrating with factory radio. Cons: Auto-EQ is finicky to setup. Installation instructions are not very informative. Limited to 4-Ohm per channel. I installed this with my factory radio using high level input and set it up in Bi-Amp mode with a set of Kicker KSS269 components. The pairing was perfect, like they're made for each other. Install manual is not clear, I had to get info online from other users and the Kicker youtube channel. Once I got the thing to auto-eq, it sounds much better than I expected. I am very happy.
