Default Rattling noise

I have a 2003 GT convertable. Everytime I'm on the gas pedal a rattling noise comes from underneath the car. It won't stop until I'm off the gas

Need a video of it. Could be a ton of things. Detonation, rod knock, cat converter rattle, exhaust leak, heat shield rattle, lash adjusters, timing chain tensioners, etc.

Does it do it at neutral, or only in gear?

Knocking only under load sounds like detonation to me.
