HI,
Thanks for letting me know. By janky I just mean nasty, rubbish so on and so forth. I flipped one of them over after reading your post to see if there was anything written on the back they both say crossover on the back I assumed they were amps due to the fact they certainly aren't small. I'm assuming someones got them wired to the front doors.
Once this whole lock down thing eases which for us in NZ is looking like about a weeks time I was planning on taking it to an auto electrician to have the Japanese toll road thing that screams at me every time I turn the car on taken out. I may have them trace the wires and see where we go from there. If they do what they're supposed to I have no issues with them staying they could do with being secured properly though as they seem to be cable tied through the carpet at the moment which is not cool.
Thanks for pointing out those threads though I'll definitely take a look may even point them to those when they have a look.
