Hi dear all, my current set up was
1) ori factory set up HU (Blaupunk)
2) epsilon pre-amp
3) 5-channel Eclipse 3650 - just install
4) Front - sony 6" component
5) Rear - Stellar 6" component
6) Kicker 12" sub

(i know all brands been mix up cos not buy all in one time, some inherit from my old car)
My questions,
1) significant 'airplane sound' after install of new amp. Previously i used 2 units cap ayam 2-channel amps but the 'sound' is not dat significant. Been checking the preamp and wirings all over but cant solved the problems. Any sifu have any idea what else need to check ?

2) if the culprit is the stock HU, any recommendation of HU (budget RM800-1.5k)?
