well you have to say one thing. Is your W7 going into a single sealed box, or is it going to go into one of the JL HO boxes? If its in a single sealed box, make sure the installer uses 1" think MDF.
Anyways, on with the amps.
This isnt too hard because the 300/4 isnt on the same chasis as the 1000/1. If you take measurements of your trunk staight across from side to side at the longest part it would give me a better idea what to work with. If worse comes to worse, you could hide the 300/4 in the spare tire well and then cut a hole in the carpet to make the 1000/1 flush with the floor.
Gut the spare tire. Make a fibeglass enclosure to house the sub in the spare tire. Then, flare the amps out at an angle going out from the sub in a MDF shell w/ fiberglass surrounding it. Basically making it look like a hurricane design. This install will be a lot of money. But looks kickass when done.
If you have any other questions gimme an email. I do this stuff for a living.
