guys esteem speakers open into a almost air tight hood, great air space. dont bother comparing it to a swifts enclosure!! i think thats the basic mismatch in this comparison.
opps sorry i dint see shrivz reply
let me add, same pio head unit from iKON with a closed boot coupled with puny JBL speakers (puny, since they are janta ones i used) in swift is almost same same according to mua.
only advice see if instal is proper, second get an amp if ur dil mange more.
