Just bought a 2003 Acura TL w 90k miles. Great car but horrible audio system. Volume at 40 is still very low. Everything I’ve read says replace the amp - bought a used amp on eBay, swapped it out & still low volume. Also noticed the only audio settings that work are the fade for left/right & front/back. All bass/treble adjustments make no change to sound even when the screen shows the levels changing. So I have low audio & no bass/treble adjustments - any ideas? Thanks!

 

I hate seeing a request for help go unanswered but I haven't heard of this one before. Maybe someone else can respond. I can tell you I would locate a unit from a junk yard and replace the one you have. It sounds to me as if one or more internal amplifier FETs have been blown, purely a guess.

 

Bren, many threads about audio on here. My 04 TL has NO sound at all. Bot an P&P amp from mobilemaxcaraudio.com for $170 new. Have not it installed yet, but think it will solve my prob. eBay unit may be bad ?? Cheers
