I’m not satisfied kasi on how the tuning was done after all the hardware was installed. Yong ginawa kasi ng installer yong tuning tenga lang kasi ginamit wala man lang maski a simple voltage measurements using a voltmeter to check on the input and output signal levels at different stages. In my novice opinion parang kulang or hindi tama yong pagkagawa sa installer and wanted to redone it properly in a meticulous manner in my own limited way at no additional cost for optimum SQ. Although newbie lang ako sa car audio, Im a willing learner and could learn fast basta pasensyoso lang yong mag guide sa akin. Can you guys help me with this, please? How do I start with the above given setup?

Thanks in advance.

First is download test tones to level properly level the gain of your headunit and amplifier. Set the gain properly for it not to clip. Download a 0db 40hz and 1000hz test tone. Place it on a disc or usb. Remove all eq settings, bass boost and any other enhancement from your radio. At 0 gain from you headunit and subwoofer off, play the 40hz test tone. Place the gain on the amp at 0gain. Up the volume of your headunit slowly until you hear the 1000hz tone. Once the tone you hear gives a different tone that is the max volume of your headunit back it down a few level Until you hear the cleanest tone. Then set your amp gain slowly until the tone you hear produce a different tone, once you reached it back down a bit, thats the max gain of your amplifier. Then go to your subwoofer gain on your amplifier. Play the 40hz tone. Remove first the rca on your speakers. Adjust the gain slowly until you hear a different tone. Back it down until it produces a clean tone. Thats the max gain in your subs amplifier. Now put back the rca of your seperates. Adjust the eq to your liking.

I almost forgot... be sure to check if your speakers are wired correctly. I mean the polarity.

You can watch all of these how to in youtube.
