That looks great, I'm glad I said something haha.

Yeah it might not be worth the risk of having to doing it again, maybe someone else will chime in further for a solution. goodluck

still working on the videos... got a little sidetracked. but! Im reppin some brands now, even though I told myself one sticker.. just Team SSA.. It just happened anyway haha.

add a white line of plasti as a divider, might set it off? something seems missing, but it still looks pretty good.

I still think All 6s and 7s was TechN9ne's best album.

Really interesting build, ill be looking out for this one.

I have the same issue with my Leviathan, for me it sounds like alternator whine because it changes while driving. Once I change out my alternator, and do some power and ground runs I'm hoping it goes away.

That looks great! Cant wait to see some videos of it in action.

Very sexy woofer! good luck with your sale.

I noticed with my SP4s when I put them in a box tuned to 24hz that it completely flattened out the sound, the high notes were even with the low low notes to the ear. peaked around 33hz. Most people wouldn't expect a sub to sound good tuned that low. Glad you got it to sound how you wanted, sometimes you just have to play with it.

For the Sp4 if you want a pretty flat response then go for around 7 cubes, and a decent amount of port area (~120 to 140in) Also I highly recommend upgrading to a different amp, the soundstream rubicons have a lot of issues with heat. Not to mention to put the Sp4 to its full potential your going to want 3-4k Anyways your going to love the SP4, they have a very smooth sound to them.

Rustoleum protective enamel works well, its very thick and doesn't come off easy. Its also quite cheap.

Awesome! Been wanting something like this.

Where's the video!? I tried to use a CD and use my phone to take a video and the CD kept skipping and stopping, so Once I get someone to take a decent video ill upload it. hopefully in the next few days. I have a few small clips on instagram though.

Alright so I was curious why the Zcons were moving so much more, so I was double checking resistance of the coils, and at the amp and such. Well apparently the Zcons are dual 1 ohm, and I was under the impression they were dual 2 so I wired them as such.. My voltage drop was that bad because the Zcons are at .25 nominal, and with rise they are around .4 to .5 at the amp. The crescendo was getting a bit warm and now I know why. I find it incredibly impressive that the amp wasn't going into protect, and I didn't blow a fuse with that kinda power. Now that I know this I'm going to take a video but as soon as I do that I'm gonna take them out and put the sp4s back in. Sketches me out running that low.

Crescendo amps run very cool usually, and are quite reliable, I'd definitely put my money on the crescendo 600.1

Ahh that really sucks, I'm going to be very careful about the placement of my runs/fuses after seeing this. Killer system though, keep us updated

Depending on what your vehicle peaks at and location of the woofer will greatly determine the response. Have you tried moving the box around? If you want to build another box also, tuning the box lower and going on the higher side of the recommended box size will help as sencheezy said.

If I heard correctly its quite a large build

haha I know right, mine started doing that recently after I lent it to a friend, the popping scares me sometimes too. Cant be good on anything.

Always nice to see SP4 builds, I still have quite a lot of work to do to mine. Ill be upgrading amps soon also, I was thinking another 3500 like you but B2 just came out with the Zero.7. I'm thinking two of those for my 18s. Take a look at those cause as you probably know, Sp4s take 4-4.5k clean.
