A constant static sound which is not effected by the HU volume, sound settings or throttle and increased with an increase in amp gain, another thing worth mentioning maybe is that my sub hit a high note while changing the source (USB, AUX, Tuner, CD), going next or previous, changing songs folder etc. which can be felt clearly even in noisy environment.
About the amp don't have any boxes with me, the sub box I got was also on demand and the shopkeeper gave it to me after opening another sub. There is a sticker underneath it which says serial no: 20877 which obviously is of no use. I am attaching the inside pictures of the board.
About the RCA's I searched nearly half the hall road, none of them were having any branded stuff :S (power cables, RCA's or a complete kit) even the stringer wire I found was after I purchased another copper wire for the same purpose and that too was just wrapped around a cylinder wire like ordinary ones are kept and if I rub it the stinger sign will be removed :o
Lastly I do accept going through all these threads, I have witnessed cases like mine and still didn't bothered for a complete paperwork thinking I'm not going into such stuff where fraud usually happens.
P.S: The nimb sticker you can see in the pictures was in the amplifier already :-#
