I have a 83 Cutlass and im trying to Murder my friend in spl competion he has 2 p3 12's I was going to go with 2 15 type R's but I said f*ck it I want to murder him so will 3 12's L7's fit in my trunk??? only reason why i want 3 is because I have been given a 750 watt MA Audio amp and I want to hook my 2000watt class D amp to 2 subs (1 ohm load briged)and 3rd sub will run off my 750 (watt 1 channel amp) . so 2 subs have 1000 watts rms each 3rd will have 1200 watts rms
