I have some stevens audio mb6's for sale. they have a high sensitivity rating and get loud. great sound too. also, they are the 2 ohm version so you can get some extra power out of your amp. message if interestedI need some advice. I have a 2012 infiniti g37 sedan, it has 2 speakers in the door and 1 tweeter in the A pilar. My current hybrid audio speakers dont get as loud as I want them to so I am replacing them for something cheaper and louder. The speakers I will be replacing are the ones Bolded below. What should I replace them with? Looking for something loud and clear that will fit in my door without major modification.
I currently have:
Fi Q 15" subwoofer
audiocubed Q1-2200.2 Amplifier
2 L6SE midbase
2 L4SE midrange
2 L1proR2 tweeter
1 l3 for my center dashboard speaker
2 JL audio 300/4v2 amps
1 Bitone DSP
