I've got an IXL18.4 and I'm thinking about trying it in my car. I would only have 3 cubic feet of volume to work with and it would be running off of 750 watts (Audison LRx 5.1K). How would that sound? Would it be peaky? Would I be able to blend it well enough to call it musical? I appreciate all the input you can offer. I don't have a ton of spare time to experiment so if you don't think this will work well I'll probably just install the JL 12w6v2 that I was originally intending on using.
