This build has been a long time in the making, it’s had a lot of setbacks but now that things are finally getting interesting I figured I’d make a build log. I’m gonna get straight to the chase here’s the current plan for equipment. Car: 2013 Chrysler 300 AWD (X) Processing: Pioneer 80prs () Helix pro mk2 dsp (X) Amplifiers: 2 Crescendo 17ks @ .5ohm (X) 2 Sundown Salt 500.4s @ 4ohm () Subwoofers: 4 Custom Fi SP4 v1 18s dual 2 (X) Speakers: 12 Sundown Neo Pro v3 8s 4ohm () 6 morel 378s 8ohm (X) Electrical: Singer 270 (X) Singer 370 (X) 100ft GP Diamond Clear 1/0 (X) 4 JY lithium 40ah () (X’s mark what I currently possess) The whole goal of this build is to hit 160dbs or higher below 40hz on music outlaw. I will dump money into it until it reaches that goal. I’ll update soon with pictures and more information.

Thanks guys, I really don't want to sell it... Hopefully it all works out and I wont have to. Id love to run this in my car at least once but I haven't been given the chance to so far. Its honestly worth more to me personally then 1500$ but you gotta do what you gotta do. :/

One of the biggest and most powerful amplifiers ever made. They didn't make very many of these so they are quite rare. one was recently tested by oldschoolstereo.com and made over 12,000w rms between the two channels at 1.6ohm per channel. Here is the link I recommend watching it as he goes into the history of this huge amplifier. And here is the manufacturers underrated specifications: Output Power at 14.4V and ≤1% THD+N (CEA-2006): 2 x 2600W @ 4 ohms 1 x 8110W @ 4 ohms 1 x 7400W @ 1 ohm S/N Ratio: 65dBA (1 Watt, 4 ohms) Effective Damping Factor: 6.39 @ 4 ohms Freq. Response: 10Hz ∼ 270Hz (-3dB) Fuse: 600A internal (external 500A minimum) Dimensions: 29.38" x 23" x 6.5" (74.6cm x 58.4cm x 16.5cm) Weight: 88 lb. Only selling because I'm moving agian and need the extra space. The top beauty/mounting plates are in automotive primer ready to be painted to match your build. Condition is excellent. Price is $1500 picked up in the Dallas Texas area, or best offer, don't bother low balling Id rather keep it to be honest. It's only going to gain value considering how rare these amplifiers are getting. I would be willing to ship it if you cover the costs for shipping. Call or text me for questions: 907-227-8213

I'm actually really impressed and happy with it. It had no lows whatsoever at first but as they are breaking in its getting a lot better. The box isn't even close to being finished, but I wanted to test it to make sure I'm going to be happy with the tuning. I'm pretty confident that I hit my goal of a 157db outlaw on music. I will show you guys pictures of it when I can do the finishing touches to the wall. If you guys want to see a much cleaner build log of this I started a thread on SMD, this one has gotten a little messy.

I absolutely loved my 18s. SP4s have such a flat response in every box I've put them in, and in a direct comparison to Btl ufos, and Zcons, they were definitely louder. So it was a no brainer as to which sub I would choose. Although... those Team Sundown 15s were calling my name... lol but more than twice the price.

Splitting the 5v outputs isn't too bad, 2.5v will be plenty. The gain will just be higher. Which as long as you have the proper RCA routing, and good grounds, you shouldn't have noise.

I unfortunately haven't gotten anything done on the build... or even sent the leviathan in to get repaired... But the subs have shipped, and should arrive in a week looks like I have a week to finish the wall. Also I got a job at SoundWorks AK, so although I'm making alot less money, my skill in this craft will improve greatly.

it's all about the box guys.. if you want musical cut down on box volume, tune on the lower end and experiment with box placement. If it's a wall a top port flattens out the response a ton In my experience. Sure you lose efficiency but ususlly it's worth it for the average person for that extra range.

What did you use for paint in the box? Nice build, if I had an suv I'd be doing something very similar with sp4s

Sure balls haha, more like stupidity. Killed my baby.. my pride and joy. They sounded amazing, and insanely loud at that power level. The other 10s were on there way too, what a setback.

Ok so if you buy a leviathan do not wire it bridged to 2ohm... Bad things happen lol...

I would ground the amps to a distribution block and run several large grounds off that to the frame in one spot. You want a single good ground to avoid noise in the system. At least this is my opinion.. others may have different opinions..

I had to take a 2nd LOOK thought that was factory....nice doorsThanks guys, It came out really nice. It really surprised me though how amazing they sound, wayy better then before. Wired them to 2ohms bridged on the leviathan just to see what would happen. With impedance rise it sits high enough that the amp doesn't protect... So that means I'll be running 1200w per door.. 600w per Neo pro. They take it like a champ.

Got one door panel done today. The big thing with these was to strengthen the door panel, so I started with 3/4 maple. Filled in as necessary and wrapped with thick leather. After some sound deadening and bracing im going to fill it with polyfill.

Nice and clean....where you get the ring terminals at....Thanks guys, all my wire, fuses, terminals, etc. are from http://www.polarwire.comThey are very good quality and expensive but I mainly use them because they are local to me.

Throwing a couple juicebox lifepo4... Wish I could afford to.. spend every dime I make on the car already haha..

Ordered finnaly.. and on a side note might start working for Perfectionist Auto Sound in the next week or so.

I'm trying to figure out what high power amp isn't Korean made these days..

Thats not really a bad place to be stuck is it?Lol no, I can't complain really I love sp4s. But that 5in voice coil though....

Very jealous of your x2cs, wish I could afford some b2 subs.. Stuck with fi for now

Ahh I love b2 idk what it is but I find it hard not be drawn to their products. How do you like the b2 mids?

The way you phrased it seemed odd to me, you said it lights up on some songs but not others. To me it sounds perfectly normal, every song has a different level that its recorded at. some will be at -2db, some will be at -36db. If your want to you can set your gain high enough that you can use the bass knob to get to clipping on all the songs you listen to. I find my bassknobs to be very accurate, but I cant say for other amps (crescendo 3500s) if you play bass kicks with definite clipping and without clipping you can train your ear very easily to hear the clipping at all times. Once you know what distortion really sounds like, it will be obvious and you wont even need a clip light. I know someone is going to have an issue with what I said but everyone has there opinions and this is mine. hope it helps.
