Sound System Questions
 

I have just bought a 2000 v6 mustang 5 spd and want to put in a sound system. I have a Pioneer DEH-P7700MP deck already installed but i am looking at putting in Pioneer TS-A6871R speakers. Now my big question is will I need an amp? If yes, what amp would you suggest? I am new to the audio scene and don't know exactly what is needed. Thanks

are you looking for speakers or subwoofers? you should def look into a better brand, maybe like alpine or such

yeah if you want the speakers to last and be able to push some sound get a differant brand, just my opinion..

I'd go with something other then pioneer for speakers...

Alpine, MB Quart, ect

ok so i will look into different brands, but i am still not sure if i need an amp. and if i do what is with the 2-way or 4-way and all that? sorry about the questions, i have never done any audio work before.

I believe, that you could you as amp, but is not 100% needed. For better sound, then yes, get the amp. the 2 way and all that means in how many different ways the power is divided into, like if you have two speakers, it can divide it into 2 ways and so on. so a 400 watt amp with 2-channels can be divided into 200 watts per channel

if you plan on putting a small amp on your "in-car" speakers make sure the rms/max of the amp doesnt exceed the rms/max of the speakers, or things will sound poopy really quick.

agreed. also look on ur headunit and see how much pwr it's pushin' out...if it is not much, then yea get an amp. and have fun w/the back deck speakers, they were a pita for me, lol.

I disagree. assuming yer speaking about amplifying aftermarket speakers.
if yer talking stock speakers there is no reason to get an ourboard amp


Most speakers are destroyed by lack of power not by excessive power.

Speakers say 100rms, 150 peak.

So you buy an amp, that does 80rms, but 150 peak. Sure, sounds like a good fit. Here is the problem, amps are usually very generous in thier ratings. And just about every manufacturer has amps that dont do what they claim.

So, when that amp hits about 50watts, it starts clipping. You turn it up to a decible level you are happy with, and it is currently sitting at about 100 output, but it is clipping.

Clipping is when an amplifier basically cuts off the top and bottom of the signal wave, which results in a very blocky looking signal. Rather than peaks, it hits plateaus.

This is very damaging to a speaker, it is trying to run a cetrain db level with distorted output, it will fry your voicecoil pretty quick.

HOWEVER,

Go with a bigger badder amp. Go with something that does 200w RMS.

To hit that SAME DESIRE DESIBLE level the amp STILL only has to push out 100 watts. The amp is working less than the smaller amp, providing the same output, and it is not clipping, therefore less damaging to the speakers. The clipping basically gets rid of the smooth movement of the driver, instead of pushing out then pulling in, it pushes out, stops, pulls in, stops, pushes out, stops. it is so fars you cant see it, but that is why it sounds like shit when an amp is being taxed to its limit.

You just gotta have the brain power not to turn it up all the way.

This ESPECIALLY goes for subwoofers.

Some assclown buys a 1000w sub driver then puts a shitty SONY XPLODE 1000w amp, which normally start clipping around 60-100watts (no bullshit) but they are trying to run a DB level that requires the amp to shit out 800 watts of pure clipping shit. That will fry that subwoofer a HELLOVALOT faster than a quality 2000w amp pushing 800 watts.


Trust me, you are ALWAYS safer to sgo with more power than needed, than to tax the crap out of an amp that just does not have the juice.

in the past when i was putting systems together i would always try to go with an amp that hits 30-50% higher RMS than the rating of the speaker. It sounds clearer at higher levels, and doesent kill your ears to listen to it.

im not in the audio industry, im not a paid installer, etc, but i have installed dozens of systems and also know a lot about audio stuff in general, home, car, etc. there are only a handful of times where i have seen a speaker blown from too much power, and normally they are running amp RMS 2-3 times higher than the speakers peak rating

ive seen TONS of shit fried from underpowering.

at the very MINIMUM go with an amp that pushes the same RMS/peak as the driver. and check those damn ohm ratings and dont forget to calculate your alternator rating.
