Distortion after new speakers/amp

So today I dropped my truck off at the car audio shop to get aftermarket door speakers and amp.. I didn't replace the factory 8" sub and amp.. Truck is a 2013 KR 4 door.. I pick up my truck and get in the road after a phone call, and when I turn the radio on the speakers sound distorted if I turn it up much at all.. I'm gonna take the truck back on Monday but out of curiosity, does anyone know what could cause that? The speakers are Kicker and the amp is JbL. Thanks

Most shops should tune the stereo, but did you check the EQ settings on the radio?
They are likely still set from before the amp.

maybe you should have gotten of the phone and sound tested in the shops lot

hopefully it just needs dialed in but I agree with Heavy_GD ya think they would have at least tested it and either adjusted it or talked to you

Keep us posted

what amp model ? speaker(line) level inputs ? or a line level to preamp (rca) converter

Lol I hear ya.. I definitely should have tested before I left..

I did play with the equalizer and bass, mid, treble were all set at 50%..

The amp is a JBL 4 channel (500 watts) and the cables are 8 gauge with interconnects.

Turn that down and see if it helps... distortion is usually caused by a frequenzy the speakers can't handle but it could also be to much powah!

I'd have to see the gain knobs on the amp to go further
