2 subs vs 1?

Question

I am planning on running one alpine type r 15, I am going to give it about 800 clean watts. Just wondering how much louder it would be to run two and give them each about 800 watts. A frien of mine has a 1500 watt kicker amp for sale (for 450), although i know doing this means i will also have to upgrade my electrical etc and buy another sub etc. Just wondering if it would be really a huge difference and if it is worth the extra say $1000 altogether

Answer 1

IF you run a second sub with the same amount of power, you're going to gain 6 db, the equivalent to quadruple the power to one sub alone.

two 15s with 800 watts each = one 15 with 3,200 watts.

Answer 2

I THINK U WOULD BE HIGHLY IMPRESSED BY THE ONE SUB,BUT IF U HAVE THE AVAILABLE FUNDS AND SPACE WHY NOT GO FOR TWO SUBS.U WILL HAVE MORE BASS AT HARD HITTING LEVELS.
