I'm happy for you Nitrous, me & a fellow team-bhp member (HarmonBro) have been hunting around for quality ICE installers in Chennai - in vain ! And yes, we've checked out both MetalEffects & Technokrat ! In fact one of those visits went so ridiculously that it warranted documentation in a separate thread...

Nitrous, can I ask who your installer in Chennai was ? If everybody's thinking Nitrous's ICE install was botched, wait till you see the "professional" tweeter install my installer (now ex-installer) did !?!
I guess Chennai's ICE salvation lies 360 kms to the east - sighhh :(
