thanx again brother ur explanations are quite understandable to me and increasing my knowledge.....ok so bridging can only be done on subs...and there isnt any option of bridge or unbridge in my mono amp...there are following three settings given in mono amp with given limits.....
Bass boost= 0-12db
X-over freq = 32hz-320hz
Input level= 6v-7mv
So far what i have done is just put my mutant bass boost "off" which was creating distortion in some low beats....
now according to ur explanation i will keep the "Input Level" to 0, my pre sound goes upto 62 fractions so i will put it on 40....but the confusing thing is should i play any song while doing all this? coz playing any song on sound level of 40 would be i think impossible....or am i missing something???
