SolerTuned Posted April 8, 2016 Author Report Share Posted April 8, 2016 Big updates. Got the new subs in the old box so that we could get a baseline score for this semester. This box is meant to be temporary and was put together quickly so that we could compete this weekend. After installing the box, we tested using a battery bank and managed to get 150.9 at the dash and 153 at the kick New battery bank! Now that we have everything hooked up right on the new battery bank, we were able to net a 153.6 @ 60hz. We'll be be tearing this set up out after the Aintloud show and trying again with some new tuning and box shape.

SolerTuned Posted August 23, 2016 Author Report Share Posted August 23, 2016 Huge changes are in the works. Over the summer, we constructed a new box for the 2Loud car. Its constructed from MDF on the inside, birch on the outside. Next, we constructed the port using a 12 sonotube, 1/2 MDF rings, and some bondo. We took the car to competition at the Sundown show and managed to score a 158.1 dB in the kick @56 hz, and 154.6 dB on the dash @51 hz. We look forward to this season ahead and hopefully securing a 160 Team 2Loud @ Virginia Tech, Team NVX, XS Power Batteries, DB Designs Build logs: 2002 Mitsubishi Galant, 12 NVX 12s, 4th order, Vital Power 700.1, 158.6 dB Kick 1990 Honda Civic SPL Build, 2 DC LVL 5 Team 15s, 2 Vital Power 700.1s Follow my builds on Social Media!

SolerTuned Posted May 18, 2017 Author Report Share Posted May 18, 2017 Updating this with our recent endeavors: We took the system to NSPL World Finals at scored 158.0 dB kick, 155.2 sealed. Took 2nd and 1st in those two categories! After that win we knew we could do better. We removed the Vital Power and D7500s lent by our teammate and began designing the system for some upgrades. Knowing we were limited on funds, we then focused on increasing the efficiency of the set up. Using the D3100s, we set her up on one SQ2200. Managed to get her up to 153.5 dB kick clamping 1964 watts at the 2Loud show in October, taking home 2 1st places. The highest we got her too was at the Ruckus show in November with 153.8 dB, taking 2nd. The car went of for a MAACO-ver. With some new decals she turn out great! We got the opportunity to pick up 2 Vital Power 700.1s. These ended up being the 18v model and our car was not set up for it... we decided to send it anyways. With the 2 Vitals, we were wired at 0.25 ohms each. Running on just the 1 D5100s and 2 D3400s, we saw voltage drop into the low 9s... As a result, we managed to clamp just over 9k watts out of both amps. (not surprising considering their 18v amps running at 9v). Despite that, we managed to get her up to 159.6 dB kick at the 2Loud show in April, taking home 2 1sts. Now that we were huddling that 160, we tested everything we could to get that score up. When I mean everything, I mean everything. Moving seats, box, adjusting vents, taping surrounds etc. We did some tweaking of the port and took her to the TDH show. After making our runs, the score DROPPED to 158.2 dB. Despite that, we took first and second in the 2 categories we competed in. We realized when testing, we failed to test the peak again. We had expected the peak frequency to go up, but it actually went down. Thus, we burped at 5 hz too high. We believe the frequency shift could be attributed to the the window bracket breaking. After some tweaking of the port we got her to 160.38 dB unofficially. We took her to the Collinsville show and got her too 160.1 dB officially, taking 1st in both categories and loudest no wall in show. Now begins the process of trying to get the electrical up to par. We have a 200 amp alternator ready to go on the car and plan to run 18V. As for the battery bank, we plan on running a couple banks of caps. To assist these, we looked into 16v batteries. The ultimate limiting factor would be budget. We are still mostly student funded, so we dont necessarily have 2k+ laying around for a proper battery bank. That being said. We are in the process of developing our own battery from 26650s lithium cells. You read that right. 5 26650 batteries in series would work on an 18V system. With enough banks we could potentially have enough reserve for a quick 5 second burp. We found a vendor selling 160 batteries for really cheap. We're going to do some testing on these to see if they will work for our application. Our goal for this season is to get the car to 160+ sealed, and 162+ kick. With some changes to the port and the upgraded electrical, am more than confident we can do just that. I'll definitely try to keep this updated and let you know how it goes!
