[QUOTE="edministrator, post: 972908, member: 18602"] Thanx kyheng, it would be a MIRACLE if they would refund me anything at all! i am just so sick and tired of the attitude of these people that tries to rip people off. He even made some of the stupidest comment: - your amp got problem lah, why u buy this amp? you see la, how to fix now??? - i "think" your crossover problem la, your MB Quart made in china one, not orginal. (I asked him how to know its an imitation? no reply...) - where you get your HU? maybe faulty leh... by the way, I paid extra RM50 for the "ground loop isolator' and some belt to tie my tube to the car seat (despite my first instalation of RM350)! They are not acting professionally and would simply give any reasons to keep you off their tails. kyheng bro, I think you misundertand my statement above, so let me clarify: 1. My crossover came with my MB Quart component speakers, so it is only reasonable to install together as it compliments the speakers. 2. I have no pre-amp in between, only my HU and my 4-channel poweramp, but they add in a device so called 'ground loop isolator' (it says so in on the device sticker) in between the RCA connection to get rid of the aeroplane sound, and i was wondering if it is the same device as a noise depressor? i have faced a very hard time with the installer, and i think in the future i would just DIY and troubleshoot myself with the help of the friendly ZTH forumers and perhaps some friends that have some knowledge in ICE. Just now I found out that they pull the RCA cable parallel together with the power cable, I think it might be the cause for the aeroplane sound too... I tried bolting earth to the chassis (the area with no paint), but still have aeroplane sound without the isolator. [/QUOTE]
