I've got a question. Im redoing my teg's system with alpine SPR's (6.5" components in front, 6.5" coaxials in back) and a pioneer 6400 head unit. What im wondering is, without a seperate amp powering the mids and highs, will I be disappointed with the sound output? or will the measly 50w X 4 from the HU give me enough power for a setup like that?

also, if I put in a single amped 10 or 12" sub, would that just blow away all the (un-amped) mid's and highs if I cranked it?

 

It might sound alright at low to mid volumes, but if you try to crank it, it'll get sh*tty, not enough power to run them.

If you throw a sub into the mix, you can play with the fader to even out the sound, but trying to crank it will result with my first statement happening. It might sound ok, but up to a certain point, probably not loud enough for your liking.

 

You can get by with powering just the mids and highs through the headunit, but if you hook up an amp to a sub and have that as your system your sub will be louder and overpower your mids and highs, and they will sound like crap when you crank the volume. So if you want everything even you would have to lower the sub, minimizing what it is capable of.

I suggest getting another amp to power the mids and highs, it will sound louder and sound clearer and better, or if you already have a 4-channel amp, you can hook that up to the sub and the fronts since the fronts are more important than the rears.

In either case, an amp will always sound better than just simply relaying the speakers from the headunit.

 

all those questions are very generalized....

i use to really like my music nice, clean, and loud. but right now, i probably can get by with taking out my amps and sub. so that will all depend on your taste.

and throwing in a 10 or 12 in the back and still blend in with your unamped speakers if you know how to tune it.
