Drivng components with the head unit?(and other speaker questions)

post #1 of 4
Thread Starter 
I always hear people say you should use a seperate amp for your speakers, especially components. But as I was looking at some, I noticed most of them have a sensitivity of around 90dB. Are these really going to be that bad with a 18w HU amp? Something else I was wondering about components: Is there a way to do something about the fact that the tweeter is closer and more on-axis to you than the woofer? It seems to me this would make the speaker really bright, and I hate bright speakers. Is there a way to compensate for this?


On other notes, how important is it to get front and rear speakers from the same brand? What about drving aftermarket coaxials with the HU amp? Last, but not least, if I do decide to use outboard amps for both the front and back, would it be better to use a pair of 2ch amps, or a single 4ch amp?(My HU does have seperate pre-outs for the front and back speakers)

BTW, these will be used for hard rock/metal, at somewhere around 80-85dB. They won't have a sub right away, but one will be added later once I have the money.

--whether you decide to amp or not is your choice. IMO, amping aftermarket speakers is the only way to go. not absolutely necessary, but will sound better (subjective).
--if you don't like the separation of tweeter to woofer with the components, figure out a way to mount closer to the woofer such as drilling a new hole for it.
--same brand not always recommended, again another personal choice depending upon preference and budget.
--depending upon how much space you have available for amp locations, wiring, etc it is up to you on how many amps you want to run. considering you plan to add an additional amp and subwoofer, do you really want 3 amps in your trunk? also, the taxing of the electrical system of your car with 3 amps could kill your alt sooner than later.
--for my car, i went with a single four channel amp to drive the front coax and rears(both alpine type s). no problems as the amp will have different settings and gains for front and rears.
--good luck with your decisions and don't let anyone tell you that you need a cap or high output alt or other "unnecessary" products for your ride.
