New Sundown Audio SA-10 rattles?? HELP!!
Ok. I have a 1.600 rated at 600w rms and a sa-10 sub rated at 600w rms. I swapped my 4ch amp for my mono amp to make sure the amp i bought works and the same for the sub. I wire it all up for 4ohms in the new 4080 box and drill in all 8 dry wall screws and then tighten with a normal screwdriver to get that extra little bit. I first tried with the gain at 1/4. Nothing would really come out of the sub will like 30/40 on my headunit. So I turn the gain up to 1/2 more output starts around 24/40 so i turn gain up a little past 3/4 the one line till its at max. I get lots more output but its like rattling which i can hear inside the cabin. Take out the sub. Play some more bass heavy music dont turn it up too loud at all. Its still rattling so its not the box its the sub. At low volume levels it still rattles. Is the sub bad? Is my gain supposed to be at 100% because they both are rated at the same rms wattage and im clipping the amp or sub? My lights were dimming also. I grounded the amp straight to trunk floor with a screw and both power and ground are 4 gauge. This rattling noise was there from the beginning so i think its the sub. Sub also came with a little gash running down the side of the cone but its not deep so i didnt worry about it. Oh and i ordered a dual 4ohm voice coil but the box had said 2ohm so i wired it as 4ohn but running in series. No matter what the gain is set to it makes the sound. When i push the sub by myself there is no scraping or scratchy noises so i dont think voice coil is blown? Thanks
