I swapped out my old sub (DIYMA 12) for something I hoped would increase output while leaving quality of sound right where it was (amazing), so I went with 3 JL 6w3's. I'm running this off the sub channel of my HD900/5.
Now the issue I'm having is that my DIYMA was impossible to locate. And by that I mean that no one could hop in my Car and say, Oh, your sub is behind me in the trunk. It blended so well and was so transparent that it sounded like the Speaker was deep in the dash. However when I switched to the 6w3s I instantly was able to audibly locate the subs a good distance behind me.
Now I figure some of this is in the tuning but after fiddling with my EQ, TA and phasing (alpine h701), I was able to blend with my mids a little better but the sub is still easily 'found'.
Any advice? The vehicle is a 4door Toyota Corolla.
