just putting new stereo in Kenwood KDC-355u with a JBL stock amplified system,

I have really low volume, when its turned up all the way you can barely hear it, I don't know what the issue is, I assume its wired correctly after checking multiple times...........

any suggestions/ideas what it could be?

 

What's the vehicle its in?

 

2001 toyota solara I must have fuked up by stock amp somewhere, cause I plugged my factory stereo and same issue, so I bypassed the amp, its working now, its definitly louder but it doesnt sound as clean as it did with the JBL stock amp, i kinda wanna buy another amp and some speakers now, fak, why is this stuff so addicting

 

Nature of the beast my friend...

 

turns out i didnt mess up the amp, i plugged stock stereo back and it was normal, but I still seem to cant get my deck working with the JBL harness still really low volume, I dont get it :S :S
