HU : pioneer Deh 6350 connect 2 pair RCA to amp.
Amp focal solid 4, front component, rear bridge sub woofer.
Can anyone advise me on the problem I meet with my system?
Recently I connect the rear output of HU to car stock speakers to fill the rear seat. Found that last time during install I connect front RCA to rear connecter of HU. So I connect back to front connecter.
Now the problem is, whenever I switch between source(USB, SD, CD,AM) and turn off HU, left side of component speaker got loud pop sound. I switch left RCA to Right, right side speaker got pop sound. I assume is RCA cable problem, but after connect RCA cable to rear connecter of HU. Problem gone. Try several times, since like rear connecter not problem. Any idea why this happens?

did you tried diff rca cable for your component? still got pop sound ah?

No. I don't have any spare rca cable. Now I connect to rear rca output and no problem already. But I can't control rear seat sound volumn.

you mean cant adjust the gain is it? could be the amp's rca connector problem.. can isolate the problem by testing with diff rca cable and diff amp..

No. I mean with my RCA connect to rear output, I can't control front,rear volumn level using hu. Coz both (component speakets and stock rear speaker)are connected to rear output of hu. Anyhow, I can adjust gain of amp to increase the volumn of component speaker. For the time being, will just leave it like that. Wait I need to upgrade anything then diagnosis again. Thanks for u help.

Would like to replace Myvi stock 4" speaker. Speaker come with Myvi really no sq at all. Have look into online available brand like blaupunkt, Sony, JVC, kicker, soundstream. Dunno those speaker have how much improvement as no review can found. And mostly for local Malaysia market only. Those price range mostly from Rm70-130. Brand like Alpine , jbl, pioneer, is price from rm130 to 240. Double the price, have more identical improvement compare blaupunkt, JVC ?

My Ride: Myvi 1.5 lagi best
Prefer SQ/SPL/SQL: SQL
File format/medium used in your source: MP3
Music Genre: Anything
Setup type preferences: Myvi stock GPS Hu. Not very good but no plan to change as just repair currently. Prefer 4", just replace ori paper speaker
Other requirements (if any): Budget around 200 to 300 .prefer brand that last long.
