Thank you Bert Taiko n Evo Taikor for your MAHAGURU advise!!!:DBert said:see the sub first... big sub needs big amp.. small sub, small amp...
If u r keeping to the RF theme.. u can look for the 1000BD which is 500 @ 4 ohms, 1000@2ohms.. more than enuff power to whack a sub...
I did play with a RF Power HX2 for a month or so.. really had fun with it when feeding it 1600w of power... plays low and quite good for SQ.. not fast enuff for demandign SQ tracks though but it plays loud
