Sounds so much better!!
Purchased this by recommendation from the geek squad tech. My Memphis amp shorted out in one channel after less than two years. I bought the Memphis sure to higher power and performance, but this Stinger is noticably better in sounds quality and distortion. I am running Kicker 6x9 and 6.5 inch combos with a JBL HIDEAWAY sub in my Sequoia. It's loud and crisp. Good right bass. A must have with the factory radio is the LC7 PROCESSOR. Anyway, I can't say enough about this amp so far! I hope it lasts longer.

High quality, 'big' sound from a tiny amp!
This is a great amp installed by a Best Buy Audio technician. IT is very compact, so it fit behind the steering column, very crisp, clean and powerful sound from this tiny device designed for marine and powersports (aka motorcycles, boats, four wheelers, etc.) but I went for it for my Chrysler 300 anyway. It has a very cool mute/volume control button that allows you to instantly mute all speakers with a press of the button, and/or control the volume level of the rear channel with a twist of the button. Paired the AMP with four 6x9" and 2 3x5" Kicker KS series speakers and it sounds great!
