mrazandrewm Posted July 2, 2015 Report Share Posted July 2, 2015 Hello fellow bassheads. I am currently running into a heating problem. I started to notice my subwoofer gets warm/hot to touch when playing full tilt for a while (20-30 minutes). I do not smell any electrical burn (burnt coils). Below is a screen shot of torres and what my box size and the tuning frequency. My subwoofer is an Incriminator Audio Lethal Injection D2 10". My amp is a Sundown Audio SAE 1000.1D wired to 1 ohm. Incriminator Audio recommends a box size .9 cubes - 1.5 cubes, 12 - 25 Inches of Port, 28-35 Hz (Average: 1.25 cubes, 18 inches, 28-35 Hz). Is my enclosure too big for the amount of power I am feeding the amp? Or should I have gotten the additional spider and optional 4-layer flat wound coil? Thanks.

Triticum Agricolam Posted July 3, 2015 Report Share Posted July 3, 2015 Your box specs look pretty reasonable. How do you have the gains on your amp set? If you clipping a little that will heat your sub up.

mrazandrewm Posted July 3, 2015 Author Report Share Posted July 3, 2015 I set my gain on the amp via the dd-1 track 5. I had to use a ddm to set the output voltage on the lc2i to ~4 volts. Could that be causing the sub to heat up a bit?

MrSkippyJ Posted July 3, 2015 Report Share Posted July 3, 2015 Yeah, you should use the dd-1 for the lc2i also F150: Stock 2019 Harley Road Glide: Amp: TM400Xad - 4 channel 400 watt Processor: DSR1 Fairing (Front) 6.5s -MMats PA601cx Lid (Rear) 6x9s - TMS69 Link to comment Share on other sites More sharing options...
mrazandrewm Posted July 3, 2015 Author Report Share Posted July 3, 2015 When I tried the first time using the dd-1 on my lc2i, I was able to max out the gain and accu-bass as well. I tried a few times because I thought that was wrong. Lol. So I decided to use the ddm to set the gain to ~4 volts (just a hair under).

MrSkippyJ Posted July 3, 2015 Report Share Posted July 3, 2015 Make sure you are using 0db setting for everything but the amp F150: Stock 2019 Harley Road Glide: Amp: TM400Xad - 4 channel 400 watt Processor: DSR1 Fairing (Front) 6.5s -MMats PA601cx Lid (Rear) 6x9s - TMS69 Link to comment Share on other sites More sharing options...
mrazandrewm Posted July 3, 2015 Author Report Share Posted July 3, 2015 Make sure you are using 0db setting for everything but the amp Okay. So when setting the gain and accu-bass on the lc2i, use track 1? And when setting the gain on the amp, use track(s) 3, 5, or 7?

mrazandrewm Posted July 3, 2015 Author Report Share Posted July 3, 2015 Cool. Thanks. I was also searching online for any dyno runs of my amp using dynamic rms. I did happen to find a website that Sundown posted the dynamic rms power (burst) dyno run at 1 ohm. Could this also be the cause to my issue?

reedal Posted July 3, 2015 Report Share Posted July 3, 2015 No. That's perfect world results, you won't see that with music. But if it worries you, then instead of using track 5 of the DD-1 cd, there's a thread on here that you can download tones from that you can search for. Download the 40hz -7.5dB and set your amp gain with that.
