I had posted this in an older thread, reposting it here with few edits. I have a 4-channel JBL GT-X646 amp installed in my Honda Brio with JBL component speakers on front door and a subwoofer in the boot. I have the amp already set in the same way as mentioned in the below quoted thread
I have set subwoofer on LPF and front component on HPF, Crossover frequencies set in some 45 deg angle in a 32-320 dial and Input levels adjusted as required with the help of the JBL amp manual. I am using a Sony XAV-22 HU receiver which is having another 'Crossover filter' setting, there is no option to disable this filtering in the receiver. My music system is giving decent output but I believe making proper settings on the receiver side can make it even better.
There is a whining sound from my speakers when I play songs in low volume. It increases with acceleration of the car. It is pretty annoying at times. Service centre guys told it may a grounding issue, but they couldn't resolve it (tried in 2 different service centres). : Using good quality wiring kits by audison/ Monster can resolve this? Hope they won't cost more than my amplifier and HU itself.
I am a newbie here and I believe I have placed my questions in right place in right way! If not please correct me.
In a typical speaker/sub set-up, we HPF (high pass filter) the components to divert freequencies above the filter we have set and LPF the sub so it receives freequencies lower the LPF settings. A typical example is HPF and LPF at 80Hz.
