So got annoyed with it and to it to a local PG shop. Problem is within the amp. The connection between the RCA’s and the board are bad and need repaired.

So disconnecting the RCA and it’s silent which make me think that it’s a signal problem or the cables are picking up interference in the signal but they are quality insulated cables so I go back to thinking it’s something in the signal source. But than I plug in another signal from a Bluetooth and c...

Hooked up a different sub that I know is good and it makes the same sound. Just rewired a new ground as it seems like that’s what it should be, but to no avail. Still making the sound. Maybe I shouldn’t have bought this amp. :/

I must have tied the relay to a constant power as the amp comes on even when the head unit is off. I had a different system in the car previously and didn’t have issues. I don’t recall exactly how I wired the relay. I had kept the original head unit. I’m getting that sound even when the head unit is...

Ok, turned the gain up and down multiple times and no improvement.

I’m not understanding what you mean by dirty pot. Sorry...

I just bought a used PG Ti21600.5 and hooked it up and I’m getting an infrequent buzz or loose crackle sound from the sub. The sub is a new JL 15w0. When I adjust or touch the gain or polarity controls the buzz or crackle presents itself. This made me think it was a grounding issue so I checked the ...

Not planning on rolling the dice. I like these amps to much to do that. Steve still does them and he seems to be the closest. I don’t want to ship them. I would rather deliver and pick up personally. I want them to last for another 20+ years. So it will get done. Is there more work that should be do...

It was the card. It had come loose. I’d forgotten that this had happened the first year I had them but was in a different car and different set up that contributed to it. Reinserted and works perfectly. Changing the crossover does nothing visually but you can hear the range changing. The ps caps you...

I’m in California. I’ll look around and see who I can find around here. I’ve had these amps since 1996 and I don’t want them to have any issues as they have been so good.

Yes it has the crossover card. I will check that. Everything on amp is original. So where would you recommend having the PS Caps inspected/replaced? Any recalls on the ZX450? I’m an original owner of a zx450 as well.

I ‘m new here but an old school Phoenix Gold owner and fan. So not sure if it’s the amp or the subs yet that are the issue. But not getting any sounds. So trying to figure it out. Checked the wiring and fuses and all is secure and intact. I looked at the amp which is a ZPA 0.5 and 4 red led lights a...
