AudioSavings diego, john,z DEFECTIVE OR REFURBISHED TRASH Inwood texas!!. I purchased Rockville dB15 6000 Watt/3000w RMS Mono Class D 2 Ohm Amplifier Car Audio Ampand .Upon initial installation i Removed old amp and installed Rockville Amplifier . All the lighting was nice but didn’t work.Checked all wiring and nothing out of whack ..Removed Rockville dB15 Amplifier installed my old Amplifier back and all was good.. I RE-INSATLLED OLD AMP BACK AND ALL WAS WELL.. I returned with much frustration and paid shipping out of pocket because seller would not pay return shipping. I purchased BOSS Audio R2400D Amplifier from another seller and it worked just fine concluding i recieved a defective product from audio savings. In order to make things right i requested reimbursement for out of pocket expenses to ship defective product back but repeatably Audio shipping would not agree to reimburse although the have free return shipping on their website.
