ZombiAlpacalips Posted March 7, 2020 Report Posted March 7, 2020 So, I recently bought a skar rp1200d and an evl10 d2. I got a temporary prefab box that's 1.85cu ft at 43hz. I have gain matched to 850 watts and set everything according to skar's recommendation 80hz and 30 for subsonic. I've even been in contact with skar trying to figure this issue out. The sub clicks and makes awful noise unless I turn the gain all the way down to 8v or below. And then the sound is almost nonexistent. I'm running from a factory headunit. I have a short video of the noise from the other day but now it's even worse. I've been playing with the settings on different test tones and anything I can think of or google to figure this out, to no avail. Any help would be greatly appreciated. oh, video is of the first settings I tried. 20200304_184022_1_1.mp4
ToNasty Posted March 7, 2020 Report Posted March 7, 2020 You dont gain match to wattage. and 1.85 cubes is way to big for a single 10 ported. which tells me its unloading ***Super Sellers List***http://www.stevemeadedesigns.com/board/topic/25829-super-sellers-buyers
ZombiAlpacalips Posted March 7, 2020 Author Report Posted March 7, 2020 How do I gain match? It said if I wanted 1k watts, after the match I should set the gain to 32.6. So i set it at 30 Just to be safe. Skar reccomend 1.75-2 for the box.
AaronT Posted March 7, 2020 Report Posted March 7, 2020 Gain matching to the head unit is going to give you the cleanest highest RMS the amplifier we'll put out when you said something for a specific voltage with a multimeter like you're doing that's a different story you just using the wrong term Yes that's a huge box for that cat and what you're hearing is the sub bottoming out Remember when under gains and head unit flat, any tinkering with the bass boost processor for your head unit or anything like that you going to change the voltage and you're not going to be matched for the specific wattage
ZombiAlpacalips Posted March 8, 2020 Author Report Posted March 8, 2020 Gotcha. I dont mess with bass boost at all. I leave it off and leave bass set to flat on the hu. I'm going to make a spacer and stick this thing in my sdr box and give it a try. Thanks for the help. I've been out of this stuff for about 15 years and everything has seriously bypassed my previous knowledge.

Its unloading. That's all there is to it ***Super Sellers List***http://www.stevemeadedesigns.com/board/topic/25829-super-sellers-buyers
AaronT Posted March 8, 2020 Report Posted March 8, 2020 Turn off subsonic or set it as low as possible. Bet it gets way worse. As nasty said, unloading, basically playing free air with no "air suspension" to dampen sub cone movement
