hey!! thats an awesome thread, probably i should have read it before going for the upgrade, i got JBL 360 watt components for the front and pioneer co-ax 250Watts at the rear and then JBL amplifier 800W, line converter and bassFx amp kit, costed me around 16.5K , but the reason i said that i should have read this thread before is probably i wouldnt have gone for the amp, as at the end of the installation i got to know that the amp cant be turned off!! , so i asked them to connect it to the ignition, now i am worried about warrenty!! had i been through this thread earlier then i would have skipped the amp part!! the other issue i am facing is, when the system is on, the amp is making a hiss sound!! can someone please help me out!! Thank you!!
