Ok this is wierd I have a A8000T audiobahn amp mono which is 800rms and im running it to 2 mtx's total power of 600rms so i know im overpowering it but i dont have everything cranked up high. Ok this is the wierd part When i plug both my rcas into my amp the subs have like barly any power at all cant even tell if its on but when i only use 1 rca it has tonz of power. why is it doing this is there sumthing wrong with the amp or does it only work with 1rca cuz its overpowering if i use 2. Please help if anybody knows. The reason I'm using the mtx's for now is cuz im waiting for my Kicker L7
might be something wrong with those rca cables...replace those first and see what happens. Also it might be a internal amp problem. Is it used, new, or a refurb.?
btw audiobahn amps are well-overrated so that amp should put out around the 600 watts your asking from it.
I changed the rcas and it still does the problem, whenver i plug both rcas in the amp theres barly any power but when i only use 1 rca it sounds great?
