That's what I'm currently working on as well, SPL. It's very addicting lol. Good thing though if you buy quality equipment, you can always sell it if you need to for a good price. Which is why I'm going with sundown audio.

 

I'd definitely go with the Sundown, Jacob's CS is second to none and the product is very dependable, underrated and holds it's value well.

Yeah buddy, Sundown SA-12's FTW!!! Very impressive subs indeed. Depending on what you're competing in, you could still win with WalMart subs. Out here the popular competition is bassrace where you compete in a class, 129.9 for example, and the goal is to get as close to that number in db w/o going over it as the run ends (30 seconds). But if you're going for highest db, WalMart subs prolly won't get the job done

Excellent choice

 

that's a lot of wires ^^^ hanging out in the engine bay. my buddy hook mine up last week and i'm happy how he done it now i know how to hook up an amp lol. the only wire show under my hood is the power wire. when i get a chance i'll take some pics.

 

Sorry op didn't mean to jack your thread There's some good information in here though.

It didn't take me long to decide to go with the saz lol. It's only $150 more (for me). Much better amp, better looking, huge power, the list goes on. Not knocking the crescendo, but I know someone that ran it at .5ohms and it went to protect, luckily it was under warranty, but still. It's rare that sa has problems. In the far future I'd LOVE to get some v2 nightshades.

And true on the cheapo subs at Walmart. But you just won't have as much fun with them, and they won't last. You get what you pay for.

 

Jack away (I was gonna say jack off but I thought it didn't sound right ). As long as information is being provided, its all good!
