    Bought this amp might have been drop or used then resold as open box and after 2 months the amp stopped working turning itself into safe mode. Took it to get it check and it’s literary not good no more. Don’t buy anything open box because (no warranty) I though I got a good deal and got the end of the stick on it.

    Doesn’t work. Goes immediately into protect mode. Was an “excellent” open box. Bought last month, just found the time to install. I Did not look at time table for returns or I would have tried it sooner. But it saying “works perfectly” with excellent open box I didn’t think I needed to. Learned my lesson, ALWAYS CHECK IF ITS AN OPEN BOX!

    I always buy Kicker items and have awesome results but this particular amplifier was cutting off/ on the whole time. It was professionally installed and they told me it was the amp. So I returned it to get my money or swap it out but there wasn’t one available anywhere so I’ve been tempted to upgrade from this one but still contemplating

    Protect mode after 8 months, took it to best buy hoping they would take care of a long time customer only to receive a rude attitude and middle finger from manager. Contacted kicker and they are going to have me ship in this China garbage for "repair" DO NOT BUY
