i looked at the shiva x and i dont like it,forgot to mention that the sub will allso be for loud bass music.i'm running 2 loudspeakers which that are only 150 w rms each,small 8 for center speaker,and two towers for surround.my reciever directs all low frequencies to the sub.this xplod has me so dumbfounded at its performance,i'm seriously thinking of just upgrading to the black one.maybe it has something to do with the sub's frequency being 35hz and my box is 36hz.it really doesnt make sense to me how this sub is able to perform like this off of this yamaha.i like re obviously and if i thought i would gain some output instead of losing,i would get the sr as im still undecided.the sub preout is the only one that has 4 volts,the rest of the channels are like 250mm volts,so the sub is very important plus i want it to look and sound good.if i wasnt upgrading plate amps,i would just keep what i have.there will be times when i want to pump the bass on music and this cheap plate amp i fear will fry.so i need the best car sub to match the dayton 500 rms watt plate amp.allso the xplod is a single 4 ohm and i would have to get a D2 coil sub which allso i dont know if the single coil or the dual coil works best in this scenerio.i have thought about a rack mount amp but that would be a lil much lol.so its come down to the sr or black face xplod.i really need some input on the sr.....
EDIT; guess i'll go with the pioneer premier ts-w1207d2 thanks for the tried help
