Summary: I used the speakers to replace blown Bose speakers in a Jeep Liberty. I had to transfer the booster from the old speakers, but these worked great! They sound better than the ones in the rear doors and will probably do the same with those later. The sound is very crisp and clear even on regular FM radio.
Summary: Great sounding speaker, easy to install, and a great price. I would buy another set if any of my vehicles needed new speakers. I placed four of them in my wife's 1995 Yukon SLT with an Alpine PDX F4, 4 gauge power, 30amp breaker, and 10 gauge speaker wire.
Summary: Bass wasn't that good when I trun it up high but tremble is so clear I have to turn it down.My stock speakers are worn out plus, everytime I turn it up my stock speaker couldn't listen it to at all.
Summary: The sound is awesome, they are loud. I bought this wit another set of 4x6 JBL GTO to install them in a 2002 TJ Wrangler. They are very esay to install. JBL is known for its amazing sound quality so you would not be dissapointed. The only down side is that the speakers come with a very fragil button to activate and disactivate the twitter fuction. Only 3 weeks of use and one the buttons is not working anymore. Overall a great product!!!
