[QUOTE="The_Councillor, post: 8464588, member: 639359"] So I told my friend I'd help hook up his amp, and subs in his car as I've done it once before so therefor I must be the expert on car audio. He bought a used amp off of someone and then purchased 2 subs The amp is a Boss 850 Chaos Monoblock Max power @ 2 OHM: 850W x 1 RMS power @ 4 OHM: 200W x 1 RMS power @ 2 OHM: 400W x 1 The subs are 2 JBL CS1214 1000 12 250W RMS 4 Ohms, SVC After doing a bit of research and reading, mostly on crutchfield, I told him I wasn't sure if his amp was going to be able to power his subs, am I correct in this? If the subs total RMS is 500 watts so the amp would need to put out between 375 and 750 Watts correct? Which I see the amp is barley capable of at 2 OHM.. Question 2: RMS power @ 2 OHM: 400W x 1...what does the "x 1" mean exactly in those ratings exactly? is that saying that that is for 1 amp or 1 channel since it a single channel amp? Question 3: Lets pretend that his amp will work His subs are 4 ohms SVC connecting to a single channel amp is this the wiring diagram we would use to make the amp put out the 400W RMS at 2 OHM?
