I just got this beast a few weeks ago.

Hey y’all friend wanted to add some bump to his truck so I suggested some Soundqubed hds2.108s. He got them on sale so now I’m gonna go ahead and attempt cool build.

Time to round some corners and jam out some baffles!! Slow going working on them before work in the mornings. Today is my Saturday, so hopefully have some more time on them. Had the heater on the last hour in the jarage. lol

Fun build, thanks for posting pictures.

I was wondering about that. I hadn't planned on running them really low, maybe 80 hz with a 4th order filter. I did kind of forget how dirty and wet the inside of a door panel can be. I don't know if I could expect them to last more than a couple years probably. I should probaly just save them for my original project. I could probably do that since I am doing my own adapters. The adapter plate will have to be pretty large so I may be able to fit an 8" even. Would I run into major issues with beaming as frequency increases? I haven't done anything in the automotive environment with active crossovers and measurements. Most if not everything I have done is in within a speakers coverage pattern in medium to large rooms. The inside of a car and working this far off axis is kind of a new thing to me. I thought about seeing if I could try and get a slight angle with the adapters on the drivers door. I don't know if that is in my skill set, or if the little bit of angle would be worth any improvements I might achieve. Am I worrying too much about this? It should be an exciting endeavor. I should have done this in my last vehicle. Instead I drove around with an aftermarket Alpine and factory speakers for 4 years at least! Thanks for checking.

I snapped another pick going by the opry for you again Jared..This is part of the Hotel I redone this when it flooded back in 2010 well the mechanical rooms anyway..None of the rooms were effected the rooms actually start on the 2nd floor..The air handlers in these were the size of single wide mobile homes.Idk if they will show up good it was cloudy as heck out even though it reached almost 80 degrees today.

You'll be fine. I personally like to double Xmech just to be sure.

Do NOT use the Auras in the door. They absolutely need a vented enclosure and a rather large one at that. If you could fashion an aperiodic membrane, it could work, but running them in your door will require a steep and high crossover point of at least 75Hz depending on your power. The cone is also wafer thin, and not what you would want to run in an auto door for any prolonged time. They make great home drivers, REALLY good monitors actually, but are not at all suited for the automotive environment.

Good choice, and thank you guys for all the SSA love in this thread.

Resistance=Heat The question really is how long? How long will a low note being played at full tilt CONTINUALLY take to overheat the amplifier internals. How long will said amp last in such conditions. Not very, and that's why comp guys are rough on amp's. On the other hand, music is dynamic. The amplifier will not see those conditions. Also you are only moving the hot spot to the next weakest link, which is the alternator. That's why comp guys be running 4+ of them. Heat (resistance) is an electrical device's worst enemy. For every 10 degrees Celsius the life span of the internal components is cut in half. I can only imagine how much you are shortening the lifespan of your amplifiers with the way you have it wired now. If you want to be real technical, the electrician rule of thumb is only run wiring to 80% of its rating. So figure out how long your run of wire is and add 20% to the total amp rating for comfort... If you want to get technical.

The second run of wire allows more amperage/current to pass from one point to the other. Its called ohm's law and is a simple triangulation between volts=amps=watts. 12,000 watts/12 volts= 1000 amps. @14.4 volts you get 833 amps being drawn. As you see more of one unit directly results in less of the other. Same thing that occurs in an amplifier when presented an 8 ohm load instead of a 4 ohm. half the ohms, twice the current available on the same voltage! Now we go to a wire gauge rating chart. 1/0 ga. is rated for 250 amps up to 12' distance. Being you have 2 batteries and the one is hooked directly to the amplifiers, you can cut the amp draw in half. So if your run is 12' or under you should be perfect with a second run of 1/0. If you were competing you would want the alternator to produce the 833 amps @14.4v, and would need wire rated to pass that amount from alternator all the way back. For a daily this is not necessary. Let me put it this way, if your alt is only rated at 250 amp's there is no need to run a bigger than 1/0 wire from it to the battery(s). What you are trying to accomplish is move the alternator + front battery current to the rear.

Ok so got it wired up for a test run on my amp. I’ll have to run it at 4ohms on my amp and his will be wired to 1ohm

All done. Gonna let it sit over night then put the subs in to hear how it sounds.

Beautiful winter day to build something.

Box is 51” wide 17” deep back height I pushed 6 1/4 and the front is 11”. I was having the hardest time with the port. I really was shooting for 15 square inches. But it just wouldn’t work. So I opted to shrink it to about 12 in per cube. After displacement it it comes out to 2.5 tunes to 33hz.

Update from finals this weekend. Ride went great. Much better than last year. Weather was pucking great. We had 8 or so rigs with us, which, was rad as shit. We got to Reno, just at the mouth of that shitty Donners pass. I sent a text out, saying how great it was all going, and how it dont get much better than this. Guess i fucked it up, because right at the mouth of the canyon, one rig broke. We where already a 3rd the way up when we got the news, and there is like zero turn around points. We all met up top, and talked together, with the man down on the phone as well. I was in a car following the big rigs, so, me being with the easiest rig to drive, drove back down to get him. We got a tow truck to get the broke rig to Sky High headquarters. Jon Rabe, we OWE you big time. He let us drag it there, said "you can leave it as long as you want bro". So choice, and thank god, with out that, i dunno what we woulda done. Anyway, got that all sorted, then met everyone at the hotel late PM. Dragging some serious ass. Got a bite, and pounded a few drinks and hit the hay. No one slept well lol. Nerves where a tad rattled and on edge. We got to the venue, and got set up, got the alt belt on to run all 4, voltage checks, gain double checks, went down our list. Went smooth. We then sat in the corner, and debated running 159.99 bass race. It is a pretty known fact that Steve Mick has that on lock, and has for years. The talk was about losing the window. If the windshield goes, all shots of getting a fine score in psyclone LOW AND LOUD goes right out the window.,, choice was made to bail outta that, and just for fun, do 149.99 knowing that is STACKED as fuck. So,.. we laned up for 499 and qualified with several others at 49.99 .. Right to the hundredth. They use the hundy, to narrow the field. So we are in. Which to be honest, i did not even think we would qualify,.. its such a stacked bracket, and to get in, you normally need a perfect 99 or 98, which, is kinda hard for us, as we havent had to really knob it in 599. We just turn it to full and let it eat, MAYBE turn it down a lil with 2 or 3 seconds to see 599. Normally we can pull a 597 or 598 just letting it eat, and not touch shit. Anyway we are in which did surprise me. That said, we made it ALL the way to the final round LOL, running into a team nemisis guy from back east that we KNOW always does well in bass race. 5,.. YES 5 ties to get by him. Which is roll the dice round. Number was chosen, and he broke out. And like that we made the final round, where we had a tie with Christian (another cali guy, so one and two stayed on the west side ) So a second overall in that, which was all gravy. Window was fine, and the 4 OG drivers that have scared me the entire time seemed OK. Psyclone run up. Running 2 clicks down (thinking we had to save for the next round, we didnt), for first day, on low and loud, we managed a 155.6 at 20hz. Not a bad score at all, but down from what we have done before at other shows. We were sweating the 4 OG drivers pretty bad, well, really bad. 1 driver had a fresh recone we installed the day before, one a month or so old recone, and the other 4 being OG as fuck from 3 years ago. Tripping,.. yes, yes i was. Also, we ran the MIC for the RTA run, probably 20 times while there testing testing testing. With driver temp changes, ambient temp changes, we even drove the rig inside where the lanes where and ran it 3 times, while everyone was eating during break. It worked,.. we put up a perfect 100. so stoked. RTA score is just as important as low and loud, or install. Got a perfect install 100 also. We managed to put up a 415 and change, breaking ALL previous records, and being the highest score ever achieved since psyclone was made a format. Even Gary Killians scores of old. So much respect to that man. So yes. We got a WORLD title. Number one on the planet. Ring paper work was filled out, colors and sizes where chose. Got home around midnight or so last night. So beat, so exhausted and SOOOOOOO proud. Super stoked how everything went. Every one there, all the Cali buddies once again, made us feel welcome, comfortable, and at home. Cant say enough about them all. Fam for sure. Below. Me, Jason (tall guy) Kenny and Christian, And kneeling is Ray and Adam. Among other great friends and fam. I cant say enough to all that have helped and supported and followed. Appreciate all the love and support all. After years YEARS of tears and blood, sweat and some frustration,.. WE GOT IT DONE........ Thanks again all. Till next adventure, all be safe, enjoy yourself at the shows and lanes. Kyle Kenny
