Kicker KEYLOC® (47KEYLOC) - Customer Ratings & Reviews

KEYLOC bass correction

This KEYLOC processor replaced an Audiocontrol LC2i for bass tuning. It flattened out the response curve of my 2019 Rav4 and restored the ultra-low bass (30-40Hz) that the LC2i could not do. I had to increase the bass boost (@ 50Hz) on my amplifier a bit and low-pass crossed over at 80Hz, and it sounds amazing. This KEYLOC does the job that I would've had an Epicenter or JL Fix processor do for a fraction of the price.

It works as advertised

I have a 2017 gmc pickup with bose system had lc2i was going to upgrade to lc2i pro but decided to go with this product instead hooked it up as directions stated then played a song with bass in it subs sounded weak didn’t realize I had the hi/lo button in instead of out as soon as I pressed the button booooooommmmm subs slamming hard now I gotta retune everything was disappointed at first but this thing does it’s job I must say

Pretty Cool

Had to do the set up process a few times, but other than that it is pretty east straightforward install.

Great product!

I bought this to hook up a monoblock amp and sub combo to my factory head unit in a non-amplified f150. It works great and was an easy setup with a quick question to kicker tech support. They were great! It makes my system sound great and I couldn't be happier!

Works as expected. Sonic Electronix customer service is second to none.
