[QUOTE="cheeto, post: 4135194, member: 583683"] Alright, I've had this AQ SD2.515 in my car for awhile now, and I have a few questions about some annoying as hell stuff that's been going on with it. Setup so far - Infinity 1600a amp AQ SD2.515 I've set the gains correctly with a 40hz test tone, but the thing won't get anywhere near loud, hardly loud enough to rattle my mirrors. The only way I could get it to be loud is if I turned on the thing called "Loud MID" or something on on my HU. However, when I turned it on and played a song like BME click at 42, where I set the gains, it smelled like melting something. I know I'm dumb for that. So today I did I set them again with a 50hz tone, making sure it was 0db. I did that and it's still not anywhere near loud. It was loud with the tone, but still not loud enough to rattle my mirrors like the 12w3 did. I got bored and put in a 20hz tone. Turned it up to 42, which was the volume I set the gains at. Went to the back to check the excursion, and It started making this huge and scary rattling noise. I'm sure it was bottoming out or something. I don't see how it would get that much excursion from a 20hz tone, but nothing from a song. It's confusing me how a 12w3 got much louder with the gains set correctly compared to a sd2.515 with the gains correctly... each had 100w over their rms rating (w3 had 400w@4 ohms, sd2.5 has 600w@2 ohms) This is really making me mad. Questions so you don't have to read all of the above to get them - Why is it only getting loud on tones, and not that loud at that? Why is it that my 12w3 bumped harder? Why do I have to turn loud mid on to get it to move? Why did it make that noise (probly bottoming out) on the 20hz tone? Any help is greatly appreciated seeing as I'm pissed as hell right now.
