3- wire world wires
4- debrez high to low
the biggest challenge here was not to have any physical changes to the stock setup. only 1 type of hertz speaker could fit (4inch mid and small tweeter). took ages to get the right signal from OEM head unit. how to u guys get that sorted out?
next was the high to low signal. because i'm using stock headunit, i was told that an high to low into the amp is a must. that causes my system to have a hizzzz sound even when volume is at zero and when volume turn to 1 the hizzzz sound becomes louder than music. hence, i've to turn to vol constantly high to overcome that problem. any advice?
the sound is definitely better than original. staging has become higher.
wat can be done about the 6" woofer under the seat?
thanks guy

I guess that you have the HiFi system and not the Top HiFi system (Logic 7).
What aftermarket amp do you have?
How do you connected the OEM HU to that amp?
