My current setup is a set of 6.5 and Hi-Vi speakers for front stage and a single Sundown Audio Sa-12D2. The front stage is run off an amazing a/d/s amp and the sub is powered (well) by my Zapco 750.2 running at 1ohm bridged.
I am buying a new car that has 6x9s in the doors both front and rear as well as dual 8" subs and 2x3" tweeters in the dash. The vehicle were buying is slightly larger inside so I am going to add more and would like some 6x9 recommendations if you would please. I will be adding a 2nd Sa-12, possibly a second 750.2 or switch to a much larger zapco (read 2k+), and need a front stage that wont get smothered by the bass while retaining clarity. The stock subs are going away completely.
Sets I am considering:
Image Dynamics CTX69
DDAudio CXS 6x9
JL Audio TR690-TXi
They need to be able to pull good mid-bass duty from 90hz and up, and will have about 90 watts to do it per speaker. From these four which is the best and why (mostly dubstep and metal with some rap included).
