good amp but second hand?
Jack Novis on 11/08/2015 3 star rating

Arrived in good time, packaged properly but was clearly second hand! I was doing a quick build so didn't have time to go through the process of returns! Still a great amp but second hand being sold as new is cheeky to say the least. Usually get grade a service from you guys, just hoping this is an honest mistake..

Darren on 10/02/2015 3 star rating

I recently had a stereo fitted at the ilford branch and I have to say the guys were great,it was in my van working before I got halfway through my I thought I'd buy shot of power to suppliment my new system and speaker. I came across the JA491 and it seemed perfect to run a couple of rear speakers so purchased it online,next day I had a call which I missed and a voicemail telling me that there were 3 left and they Had no boxes as the boxes were damaged,well my alarm bells started ringing but decided to wait until th unit arrived. It duely arrived in an undamaged correct box but upon opening it the amp was most definately second hand,as I had feared.........there were scratches and scuffle marks all over the amp in places consistent with being fitted into something,blood boiling but not surprised due to the voicemail I called car audio centre,a pleseant chap took my call and I explained the situation,he went away for a few minutes and found out the "details" of what happened and offered me an upgraded amp for the same price as the damaged one with their apologies,which I happily accepted as I don't want to rock the boat,just want my amp! Dunno what the initial guys agenda was but the second guys proffesionalism was a relief and I am now a happy chap.
