I had a pair of L7's ported but not sealed, i assume they would sound like a dub 6. Hifonics amp would work, i wouldnt use them again though, my new Audio Que amp gives such a cleaner signal, make my woofer happy.'
As wires go, depends what your buying for $50 you wont get much quality of a kit (and even worse for $20) Thickness of the wires, wire strand count, rcs quality, twisted un-twishted, fuse holder, fuse size, there allot to consider. Personally if you want a high quality and good price id go with Knu Konceptz. There wire kits will give you everything you need and top quality.
