Boss NXD3500 car amplifier hooked to an Onkyo 7.2ch home amplifier
Well Hello, im new here so please dont make fun of me, I have a Boss NXD3500 mono class D amp hooked to a Pioneer 1000w subwoofer that I removed of my car due to space limitations and the problem of that huge sound.
So now I have it installed in a room with an Onkyo amp, I made a rig with a car battery and a UPS so it can recharge the battery and 3 relays so when the amp turns on the UPS turns off and vice versa (That was made due to interference when charging the battery and the amp turned on)
First, I wanted a house amplifier for my subwoofer but didnt find any.
My problem is:
I cant have too much time out of my battery (it dies) and my UPS cant recharge it fast enough, so I was thinking of those 30a 12v dc power supplys used for LEDs, but when I hook a 12v power supply to the BOSS amp I get a hiss out of the subwoofer.
Anyone knows a hint on what can I do to remove the hiss? a diode? a proper power supply for the amp?
