Here is how the vast majority of people have no idea how much installation and prep have to do with the sound quality and not the price of the speakers.
I had a $40 pair of Kenwood 2 way speakers in my ford explore up front. I was powering them with the pioneer HU.
My friend had a $300 dollar Set if JL Audio 6.5” components off a nice Memphis Audio amp.
My speakers blew his out of the water in regards to sound quality, ability to reproduce a full audio spectrum, and midbass and bass down to 40hz. MoSt people thought I had a single 8” sub when I turned the 15” sub off.
Difference was my friend just bought the speakers and installed them in his factory untreated doors. Just thin, hollow sounding, acoustically deficient doors like 90% of cars.
Me on the other hand cleaned and degreased my doors. Installed two layers on 75% of the inside of the outer Door skin. Two layers on 90% of the inner door panel. And three layers around the speaker hole itself.
It’s like comparing a sub in a 1/4” plywood box compared to a solid 1.5” double walled MDF box.
Sound is energy. Tap on your door. That sound is the energy from your hand going to the door panel. That thin flimsy metal and anything that vibrates robs that sound energy. If you want the most out of ANY speaker install preparation and sound damping is key.
I proved time and time again that it’s not how much money you have. It’s how you do the instAll. You don’t need to spend a lot of money to have great sound. You just need to spend some time.
I spent about 2 hours on each door. But the outcome was welll worth it.
