Hey guys can y’all help me . I used amplifinder to find an amp that matches my 10inch kicker compr 2ohm. It can get 400rms . Using amplifinder , I found that kicker cxa400.1 was a good choice for that sub. Reading into it I saw that this amp can do 300rms at 2ohm (since my sub is 2ohm). I’m wondering how much I should set my gain because before this I used to have a 10inch kicker compc that could handle 250 rms and the amp was a kicker cxa300.4 . So a 4 channel amplifier. After reading stuff I saw that for one channel the amp provided less rms than the 250 that my sub could handle. Sooo I turned the gain and bass boost all the way up . Idk if there was slight distortion , but it definitely sounded good and really loud and it kept me satisfied for months. However randomly one day the sub blew . This doesn’t make sense to me because the amp rms for one channel is lower than the sub . The sub can handle more . So how did the sub blow and not the amp. So now I got a 10inch compr 2ohm that can handle 400 rms and the kicker 400.1 that can handle 300 at 2ohm. I hope this is a good choice .I guess my question is when should I know when to stop adjusting my gain because it sounded fine months ago with my compc, but it ended up blowing. I’ve watched videos on doing it by ear and a multimeter , but the ear method clearly didn’t work for me because the gain just seemed like a volume knob and I didn’t hear distortion in the sub, it just got louder. And the multimeter one is confusing for me because if I do the math, the square root of 300rmsx2ohm for the amp .. is lower than the square root of 400rmsx2ohm for the sub. I know that that’s my target voltage but which one do I do and is it really that accurate. I also don’t know if my multimeter is good because it kept jumping to 70 or so on the AC setting and it would never go to 0.
