tried to tinker with the old and new HU's balance. mahina talaga si front left. ano ba mga sir ang magandang replacement na cheap but good quality?
Tama yun conclusion mo. However we cannot pinpoint that unless you have that checked. But yes, it's either the wiring or the speaker. More often than not, it's the speaker but on your "pero may song na malakas naman balanced output ng left and right".. it might indicate a wiring problem too.

If you have the cash, you can either have it checked muna before upgrading... or just go with the heck on it and upgrade your speakers. Even if the problem isn't your speaker and your wiring.. you'll still reap the "benefits" of a non-stock speaker naman
