Such an upgrade over the kisloc. Definitely needs its power from the battery. Subwoofer sounds amazing with the bass roll off gone. Had to buy another one
I ordered a Kicker KeyLoc that arrived next day and was properly packaged. Unfortunately, the device would not program, however Sounds Good Stereo went above and beyond to troubleshoot. They engaged their Kicker rep, and they decided to send out a new one to resolve my issue. I received the second one quickly, and it programmed immediately. What a difference the dsp made for my sub frequencies. It completely flattened out the heavily eq’d sound being fed into my amplifier. This company is great, and I would definitely recommend buying with confidence.
