I'm not sure, I called their number from their website. Actually last time I dealt with Strathfield they were really good. I had a stereo installed by some company in Joondalup (forgot who), anyway got it back, 2 of the speakers weren't working. So took it back for them to have a look at. Came back 2 hours later and the guy said got some bad news, your new stereo is faulty (bought frm Strathfield) and also someone reversed into your door when i was moving your car! The whole drivers door was caved in and wouldn't open. So pretty p*ssed off drove down to Strathfield told them they sold me a dodgy stereo. The guy asked where I had it fitted, told him, he looked at me funny and came out to look at the stereo. Pulled it out and pointed out they had wired up the speakers incorrectly! Morons. He reckoned he was forever fixing up their fuck ups. Can't remember the company name, began with an M, but obviously never went back there again.
