Ok i have a ALPINE MRV F450 5 channel amp and CDT CL-61A component speakers and ED K 10" sub

My amps manual says to set the gain this way:

Set the MRV-F450 input gain to the minimum (4V) position. Using a dynamic CD as a source, increase the head unit volume until the
output distorts. Then, reduce the volume 1 step (or
until the output is no longer distorted). Now, increase
the amplifier gain until the sound from the speakers
becomes distorted. Reduce the gain slightly so the
sound is no longer distorted to achieve the optimum
gain setting

is that how i should set my gain or should i just max it out ? ;p

Also what should i set my crossover frequency for speakers?

And what should i set the crossover frequency for my SUB?

Thanks

 

Im not a boomer. I like my bass to sound like its coming from the front so I put my x-over for the subs at 60 hertz. My mids play 60 and up, and my center plays 100 and up. If you play alot of bass loud your not going to want to x-over your mids that low or youll probally blow them. If your a boomer Id go at about 80-100 on the sub, and let the mids play 80-100 and up. Sounds like you got your gains set pretty good. Id do the fine tuning w/ music you listem to the most. Everyone has differnt opinions on gain setting. To do it by the book you need a osilascope, but what average joe has one of them in the garage. Hope this helps.

 

DO NOT MAX YOUR GAIN OUT.. it is not a volume control!!! ... it basically calibrates the amplifier to the head unit. you shouldnt be looking for distortion but "clipping" ...

see if you can find a 1000Hz test tone to pump through your speakers...

turn the gain on the amp down pretty low.

increase the volume of the head unit until you hear it "clip"

you will notice a definite tone change.

decrease the head unit volume one or two notches.

now do the same with the amp gain.. increase till you hear it "clip"

now you are all set.

(many people dont know this but it is an amazing way to tune your system. you will blow less speakers this way too...i have yet to blow a speaker/sub .. and i crank on them pretty hard )
