luckyishere Posted August 22, 2012 Report Share Posted August 22, 2012 Hi, I have 2 FI SP4 15" D2 fully loaded on 2 crescendo Bc3500D's . I have them currently in a ported box tuned @29Hz. I am looking forward to put them into a 4th order designed for lowws for demoing and hair tricks. I have a little idea about the fourth orders. It will go in a full size SUV so space is not an issue. Please help me out designing a 4th order for these..

luckyishere Posted August 23, 2012 Author Report Share Posted August 23, 2012 I have those amps strapped @0.5 ohms .. Holy fuck And still voltage drops till 12.8 volts and they hardly ever trip. Moreover they don't get hot they are some nice monoblocks..
