@Xtremevol what are you powering them with and how much? I assume you are running a 3-way upfront. Are you running the SI 3-inch and 1-inch or using something else. How do you like them? By chance did you run the TM65 previously? If so I'd be curious your opinion of the differences. I have a brand new set of TM65 mkIIIs I can use.
Originally I wasn't going to upgrade the OEM mids/highs and just do the stealthbox. I'm still tuning the box but I'm just not dialed in yet. I prefer sealed boxes because I find they give me the best sound for a wide variety of music. Since the stealth is ported, it's taking me longer to get is dialed in for my tastes. While it gets more than loud enough, it just isn't to the level of punch that I prefer. I'm hoping I can get it where I want but I'm also considering it may just be showing the limitation of the OEM speakers and the blend between the doors and the subs just isn't there. So I decide the pull that trigger I want to put 8s in the doors so that I can get that blend covered.
I was running the Morel Carbon 63A. Still using the mids and tweets though. Was wanting more mid bass and for the price they were worth trying. I have had these installed for a couple weeks and still need to tune them. I only got time alignment and crossovers set so far. They definitely added the mid bass I was looking for. I got them crossed at 60hz too. These are the only SI products I have tried. I am powering them off a Mosconi Pro 2/10.
