Terrible experience
Terrible experience! Purchased a mx4 amp and on the first day of install I noticed the amp would cut in and out. There is something wrong with the lpf switch. However, it does not always happen and can't get it to happen all the time. Customer service said I could return the unit using my own money. if they could verify the unit was truly defective I would get a refund. However, I was told that they could not replicate the issue and a bunch of other things I end up getting a 20% coupon off another purchase on their website and they would lose my shipping money.
