LVL4JEEP Posted May 12, 2011 Report Share Posted May 12, 2011 (edited) Alright so I posted sometime a few weeks ago about a new box to build. (Used torres box builder) I ended up doing 3.25cuft @ 35hz. Manufacture box size spec. Got my box all together and get to tune it. Shit gets real loud but the sub its getting hot to the touch and I can smell coil burning again. I did the 50hz gain setting tutorial w/dmm and still getting the problem. Earlier in the week I had 3.8cuft @ 29hz and it was too low for me, but I had no coil issues.. only thing is the sub was bottoming at full tilt. Am I tuning this wrong?? Should I do it by the ear with all doors closed? Or how I normally drive the car (windows down, ect.) I also checked all my connections after tuning. Everything is good. I'm going to call DC later on and see what they have to say too.

ChevyBoy95 Posted May 12, 2011 Report Share Posted May 12, 2011 Have had level 4s for a while, they shouldn't be getting hot that easy. I pound on mine for 20min at a time and the sometimes get warm. Only time they have ever gotten hot is on burps, and still I couldn't smell anything. Gain too high probably Quote Best Score to Date : 160.5 dB Outlaw (47Hz)[4 XM 15's & 2 Taramps Bass 12k's] BL : http://www.stevemeadedesigns.com/board/topic/147800-chevyboy95s-4-15s-7krms-wall-1533-db-on-half-power/YouTube: http://www.youtube.com/hitemwiththeflex/ Link to comment Share on other sites More sharing options...
LVL4JEEP Posted May 12, 2011 Author Report Share Posted May 12, 2011 (edited) Well on that note what should I set gain with. DMM or ear? If I do it by ear what tone should I use. BTW. In the bigger box I had.. It never got hot and the gain was set higher than it is now. About 1/8 of a turn. Is 80hz too high for the amp xover?

WCA Rusty Posted May 12, 2011 Report Share Posted May 12, 2011 Scope is for sure the best way to go, try turning the gain down and see what happens. Quote DC AUDIO Phone Number 1(855)SPL-DBZZ Built by Competitors, for Competitors. Link to comment Share on other sites More sharing options...
JustinWilson Posted May 12, 2011 Report Share Posted May 12, 2011 Agreed, turn the gain down all the way if needed and try it out. Keep us informed. Also do you have access to an o-scope?

LVL4JEEP Posted May 12, 2011 Author Report Share Posted May 12, 2011 (edited) Well I don't have a access to an o-scope. I'd love to set it with that. I checked my gain and its inbetween 1/8 - 1/4 of a turn from the min setting. I turned it down more and its barely moving the sub. Something not right here. Is it the box? I changed nothing but the box. What I don't get is my gain was at 1/2 in the other box and the sub never got hot. It was fine.
