Hey All

so im looking to add door speakers on top of my two already installed 10's. ive picked out:

4 clarion 6x8's (300 max and 60 RMS at 4 ohms) (Link Below)
+
2 alpine 4-channel amps (600 max and 50 RMS x 4) (link below)


basically what im thinking is using two amps, one amp per two speakers so that my amp is not being over powered. (i see it as if i had all four speakers on one amp, when the bass hits it try's to draw 1200 W from the amp, which it cannot support. where as if i had 2 speakers, it would draw 600, which it would be able to fully support the speaker. i'm guessing RMS would become 100 because only 2 speakers are connected??)

omg...

First... forget everything you think you know about this.

Second... get one 4 channel amp like you mentioned and hook up 4 speakers similar you have mentioned and make sure the x-over frequency isn't any lower than 125 hz for these speakers. Don't turn your gain control past 1/2 way and please stop there. I'd suggest a professional assist you with the install.

 

^^^ I agree, dude, stop while you are ahead. One 4 channel amp with sufficient power and the proper speakers is all you will require. I am going to guess you have a Ford or Mazda for a vehicle. Keep it to a 6x8" in the rear and if you want better tonal response, a pointsource or oversize 6.75" component set (with a adaptor plate) for the front speakers.

 

can you explain why this is a bad idea/ why it wont work, instead of talking to me like im a retard?

thx for the info.

 

Ignore the power claims of a amplifier. The only one that is of any importance is the rms power rating, in this case it was 50w x 4. That is the only real concern. To gain a difference in output levels that you would hear as louder, you need to double the power, in this case to 100w x 4 rms. Amplifiers are designed from the get go to handle increases in power upon demand. What you are proposing though is a waste of space, wiring and $. Keep it simple, if you think you need more power to keep up with the bass response, a larger 4 channel amplifier would be the way to go.

The speaker is only ever going to reproduce what it is given. Have a 50w amp, that is all the speaker is going to produce (unless the amp is underrated but even then generally it is not by much). The amp is not magically going to produce 1200 watts to try and keep up with the bass response.

The amp will only deliver what it is rated for at the impedence it is operating at. If your speakers are 4 ohm, look at the 4 ohm rms rating on the amp, that is what your speakers will have delivered.

Multiple amplifier set ups can and do work great. Is it necessary in your case, probably not. Two amps are a breeding ground for noise in most systems, it also takes more space to install them and more wiring to hook them up. That equates to a waste of $ that you could invest into better speakers to improve the sound quality of the system in your vehicle.

 

thank you

 

Who's talking to you like you're a retard.... There is rarely a polite way to tell someone that their conceptions or their knowledge of what they are talking about is totally incorrect.
