Hi, first of all I'm kinda green to audio and stuff.
I have Vibe cbr10 evo(400rms) and MP TUBE 30(240rms or something) subwoofers I know they are terible, but thats what I have for now. They are both connected to Pioneer GM 9601 monoblock ( 1Ω-1200w, 2Ω-800w, 4Ω-500w)
I want to ask is it good that I use them both at the same time, because I believe that they both sound different. My gain is at max level and my frequency is 100hz I believe.
I�ve heard over the years not to mix subs but I don�t know if it can cause damage. I�m not familiar with those brands and would guess you�re in Europe based on searching the products. I don�t know if those are decent brands but that�s a pretty legit amp and will blow them especially with the gain cranked. I�d take a look at barevids on YouTube. He has a great video about setting gain and he�s in Britain so more focused on brands available in your area (if I assumed correctly)
If you keep the gain turn all the way up you shouldn't have to worry about it for to long lol. Don't mix them. Pick one or the other and put it in a good enclosure.
