Question Which dummy resistors do I need?

I am new to electronics/audio.

The previous owner of my Peugeot 308 (2012) installed the Focal IFP 207 audio kit.

I have tried three separate head units (different makes and models) but could never figure out why the sound kept dropping out.

Turns out it was the resistance of the speakers in the audio kit (2.6Ω), whereas general head units aim for 4-8Ω.

I got help from a guy on Facebook, who suggested buying 4x 2.2Ω 2W resistors to act as dummy loads.

I installed them and, to stop them touching each other, covered each one in insulating tape.

This worked a treat with my Pumpkin ND0286B for a few weeks, until one day, there was smoke coming from behind the head unit!

Turns out one of the resistors overheated and started to burn through the insulating tape.

I wasn't aware resistors got hot and covering them in insulating tape certainly wasn't helping!

He suggested I got higher wattage resistors and find a way to stop them touching without using insulating tape but there has been a bit of radio silence from him since this advice, so I am hoping you guys could pick things back up?

Any suggestions to what I would need?
