I had tcabs made for the older versions and i thought they were 350 rms... and i see the new ones are 250 rms.. i may be wrong just tell me if i am. Just wondering if it would be ok to use the same boxes made for the older ones. thx

mark's designs may be vehicle specific....the only other variable would be if the thiel small specs are alot different....if they arent your ok but if they are its luck of the draw....a change in vehicle may or may not affect much....bottom line try it on progressive amounts of clicks on the head unit and see how it sounds....amplifier gains set correctly of course

I would agree yes and yes....after running the specs and some guess work on tuning I think they will perform similar in your old box....let us know how it turns out
