I have a 2004TL and the stereo volume is not loud enough anymore. I bought a replacement amplifier, but the result was the same as the original when I hooked it up.

 

where did you get your replacement amp?

I bought one on eBay that produced nothing, no volume at all. Then I bought another on eBay that matched the original amp.

 

It's possible that both your 'new' amps were duds.

 

The forum where you originally posted, the AcuraZine User Help, Support & Suggestions Area , is meant for problems, comments, and suggestions for the website itself, so I moved your thread to the car specific forum applicable to your vehicle.

This was explained in the sticky thread at the top of that forum, or click here if you can't find it, which will explain why you shouldn't have posted your thread there.

 

99.9% chance those eBay amps are all bad. Every single one of them!
And if you happen to buy one and it works during the summer or temperatures above 70 degrees then just wait until it gets cool outside or worse it gets cold. That will really show you how bad that amp is Because when they go bad they can still play when warm temperatures but when it's cold it won't play at all..
