A Few General Questions

[Damaso87 10+ year member]

Hey all, i've been browsing the forums for a couple weeks, and i simply haven't found anything that really answered the questions I have.

I recently just got a '95 blazer from my brother, and everything in it is stock. I already bought and installed a HU (Pioneer P860), and am now in the market for some speakers. I was looking at a set of Alpine SPS-170A's for the front two doors. I have no idea what the difference is between Co-Axials and Components. I most likely am going to power the speakers through the deck, since I want to keep costs minimal.

1. What is the difference betwwen Co-Axial and Components?

2. What is the difference between installation ease of Co-Axial and Components?

3. What is a crossover? What does it do, is it necessary, etc?

4. Is there a possibility of the speakers not being compatable with the HU? (AlpinePioneer)

5. Should i buy a small amp to power the speakers to avoid running them with the HU? (If so, what amp?)

Any help with the above would make my day, and as mentioned, im not really on a budget. However I dont want to spend a fortune on a truck that will be scrapped in ~ 2 years (the thing has 220k miles on it). For reference, I have completely no experience with anything-audio. Thanks!

1. What is the difference betwwen Co-Axial and Components?

the main difference is that a co-axial has the tweeter in the midbass in place of the dustcap while components have a seperate tweeter and midbass. generally, you will get better results with components.

2. What is the difference between installation ease of Co-Axial and Components?

the co-axial will be easier to install because you don't have to worry about seperate componts and a crossover. with components, you'll have to find a mounting place for the tweeter and crossover.

3. What is a crossover? What does it do, is it necessary, etc?

a crossover is necessary when using components. it limits the range of frequencies sent to different componets to maximize their performance.

4. Is there a possibility of the speakers not being compatable with the HU? (AlpinePioneer)

there is a possibilty if the ohm rating is below the minimun ohm rating of your hu.

5. Should i buy a small amp to power the speakers to avoid running them with the HU? (If so, what amp?)

an external amp is not needed. however, it does greatly improve the sound and performance of your speakers. if you plan to get an amp, find one that produces the same if not a little more than the rms rating of your speakers at it's ohm rating.
