    Hello All,

    I had a shop redo my stereo system, They replaced the speakers and added an amp. Now I notice a bit of "white noise" when the volume is real low when i'm playing CDs, but I don't notice this when i'm playing the radio. They had to use "hi-lo converters" during the process.

    I was wondering if this is normal? Let me know. Thanks!

    It's hard to say if this is normal, since I can't hear it over the internet, but if the upgrade sounds worse than the stock system did at similar volume levels, then I'd say, no, this isn't normal. Maybe a ground loop between the amp and the hi-lo converters, or the converters and the head unit?

    Could be a grounding issue or maybe the gain settings on the amp are a tad high.

    If it doesn't change \/\/ith engine RPMs, it's a gain issue; I don't seek to offend but it sounds like they did a slightly cheapo job, tapping into speaker-level outputs.

    Then again, if your car is a 2006 or ne\/\/er then they had no choice; the signals are all digital at every location I found other than the speaker-level outputs from the amp under the passenger seat...

    I find the stock JBL system has all the features I \/\/ant except a dedicated bass output for my sub. Tap into the lo\/\/er front speakers, though, and the total sound output is not affected; then bring the speaker-level sound into a separate, dedicated sub amplifier hooked up to only your subs and you'll have crystal clear sound from all sources.
