Ryval V8001 radio static

[streaker]

I have this amp hooked up to a 10 inch sub works good with a cd or ipod but on radio I get static I’m using the SPEAKER LEVEL INPUT now I’ve traced it to that.... there is 5 wires on that speaker l, r + and _ and then there’s a ground so five wires in total I grounded it to same spot as my amp still static I unhook it static I turn amp off and radio comes in fine this is driving me nuts and when i move that one ground wire around in the air it makes static.. any help would be awesome thanks

Sounds like the amp's switch mode output stage is not properly filtered. This can cause havoc on radio reception and is not all that uncommon with class d amplifiers. I'm pretty sure this is your problem since you state that the amp sounds fine when using cd or iPod.

If you have enough slack in your cabling, try to move the amp around and away from the vehicles antenna as much as possible (carefully of course), and see if the static goes away or is at least reduced.

That does seem to help as im moving it around it makes the static cut in and out,, problem is dont have any other place to put the dam thing does that ground from the speaker level need be conected? it dont seem to make any difference,, it there a way to shield the amp this sucks for now i just wired in a switch to the remote wire to shut off amp when i want to listen to the radio im going to have to try and find a spot for this amp in my car mazda 3 not much room under the seats is heater vents

Unfortunately there isn't any "easy" way to shield the amp

you think it would be ok to put it in the spare tire well or could heat be a issue thats the only spot i can think of
thanks for your reply

You may, or may not have issues. It's hard to say, but you can try it easy enough and see. I'm sure that that amp has thermal protection... you may want to check into it though
