Never heard one play before. Infinity speakers usually sound pretty decent though. I have Infinity Kappa Perfect components in 2 of my cars and I love the sound.
Do you not have the stock setup in your truck?
No. When i bought my truck it had Kenwood speakers and a Kenwood DVD player and also 2 10" MTX Thunderforms subs under the rear seat. So never heard a stock system.
My infinity Kappa Perfect components sound awesome though. Very loud and clear. Still got the subs. Need to upgrade them though.
The stock infinity system sounds clean, mine did anyway. But it's definitely not enough thump. Gotta be able to turn it up to like 22 and feel your inner ear being tickled. I mean how are the ladies gonna know I'm cool if they can't hear Def Leppard from a block away?
