I have a 96 toyota avalon was thinking about installing a sub and amp. I am leaning towards getting 1 10" Alpine Type R and putting it in a bandpass enclosure but i dont know the difference as to which is better dual 2 ohm or 4 ohm. I dont know how to match the amp either the sub cranks out 500w RMS and 1500W peak power am i supposed to get a 1500w amp or just one thats 500w RMS. And do u just match 4 ohms to 4 ohms or is it different? Gonna buy everything off ebay just wanted some help and to hear some opinions. What kinda enclosure would u recommend?
