1. I have never had an external amp so no knowledge in this area. Here is what think I need to hook the subwoofer up to the receiver. Sub out from the receiver to the Inuke 3000 DSP in (something like PYLE-PRO PPSJ15) and then this type of cable from the Inuke 3000 DSP out to the SpeakOn connector LilMike states in the materials list (Pyle-Pro PPSS30 30). If it is not bullet proof please also describe how to wire SpeakOn connector to the Alpine SWS 15D4, I have just never done it before so need some hand-holding.
2. I am building this out of 3/4" maple plywood so great quality however plan on just plan on painting it black. What is a normal cost effective means of getting paint onto the speaker (I have seen some info on dedicated speaker paint like DuraTex as well as bed-liner paint). This speaker will just be placed and not moved around much, I am assuming the bed-liner or dedicated speaker paint is used for durability for someone that might use these speakers gigs, if I am incorrect just let me know.
Again, thank you very much for the helping hand.
As others said, you need a signal cable. I use an RCA to 1/4" phono, works OK. An RCA-XLR will work too. No need for a bump box (unbalanced to balanced converter) in most cases.
Since I always wind up needing a custom length, I usually buy a spool of decent speaker wire, cut what I need, and buy some honest Speakons from Parts Express, because proper connectors matter. They're not expensive either. You need two of these
to make the cable and one of these
to put in your speaker cabinet. I install the cabinet speakon with a 15/16" drill bit, that seems to be a perfect fit. I use a little speaker caulk or duct-seal to make sure they are airtight though. They screw in with a pair of #6 X 1/2" wood screws.
Since the speakons I linked (and use) are 2-pole, they are pretty easy to wire up, just keep the (+) and (-) straight. I generally put the cable with the polarity indicator into the (+) pin. The cable can be assembled with a phillips screwdriver. The speaker connector I linked to will require soldering.
Wiring a dual-voice coil woofer can be tricky, you can choose series or parallel, and you have to keep polarity straight. There are lots of guides on the web. This
is one of the best I'm aware of.
Painting? Simple 9" paint rollers like you'd use on a smooth interior wall work well. Seriously - a short-nap roller will work great. Before I started spraying, I rolled a LOT of my cabinets, and I still use the roller on the big ones, when I bother to paint them. Exterior latex will work fine, and you don't need the expensive stuff. The tougher coatings are definitely warranted when gigging, but gigging with LilWreckers would take a LARGE truck.
