If your front speakers are under the front seat, you are not getting clean sound from them. What I mean by this is your mids and tweeters are directional, if you're getting the sound waves from reflection from under the seat it's not going to be as clean as if it were pointed somewhat towards your ears. Subs are another story, your ears cannot determine so easily where bass sound is coming from. What's wrong with putting a set of rear speakers in the back doors with an amp to increase the volume of the rear fill? I would add an amp to the rear speaker line using a four channel amp and just use the four channels for the back sets of speakers.

If I ever pull the dash, I will replace the dash speakers, as I know the front speakers under the seats suck. They are also very old Koss 3 way units from the 80's. LOL. I am liking the idea of an AMP to the rear speakers and using that amp to add the second set. I am not looking to mount any in the doors, though. I am thinking on the pillars in the corner or on the roof facing forward. | | | Re: adding speakers?, | Joined: Feb 2018 Posts: 224 Likes: 19 enthusiast | | enthusiast Joined: Feb 2018 Posts: 224 Likes: 19 | I am by no means a sound expert, but I have learned (did it and wasn't happy with the sound level) that just placing a speaker in a box and laying it on the floor (even if powered by an AMP) that you may not get the sound volume out that you thought.
By having speakers in the dash, the sound is being reflected off of the windshield back into the van/your face. Yes, most speakers are directional, but placement of a speaker is important. The other issue is that a common dash speaker was around the size of a 4x6 and when powering with an amp, most 4x6 speakers wont handle a bigger amp. To add to speakers in the dash, you have a space issue in most cases, the passenger side isn't the issue, but usually it's the drivers side.
You would be surprised with the importance of placing a speaker and the reflection of the sound waves that will make a huge factor in sound levels.
My only suggestion is, don't point the speaker in a direction where the carpet/seat/leg will absorb/block the sound. | | | Re: adding speakers?, | Joined: Feb 2002 Posts: 522 addict | | addict Joined: Feb 2002 Posts: 522 | My Pioneer touch screen and my old Alpine have a sound correction settings so the sound to the driver seat is delayed.
