4-channel amp

[BigPimpin18 10+ year member]

Right now I am running my four speakers off of my deck. If I buy a four channel amp and left the bass down, would it not distort at higher levels?

I guess wut I'm trying to say is that I have my subwoofer output up all the way, than the bass up to like 5 and the treble up to 4. When I turn it up my speakers can hardly pick up the tweeter notes, so if I buy a four channel amp and turned the bass down on that would it not make the speakers play more of the bass notes?

you are kinda hard to understand, but if i understand correctly you want to put a four channel in your car? are the speakers you are talking about stock? If they are stock, amping would not be that good of an idea. Turn down the bass on the headunit, you might be drowning out the highs.

just don't play any music that has a lot of bass.

You should tune your system with the deck at zero or float across the board. Then adjust your amps accordingly. You will get better response from your speakers.

BigPimpin:

Right now, you're running your speakers off deck power. There are two reasons that I can think of as to why this poses a problem:

A: not of enough power. The lack of power is causing you to try to overcompensate the bass, thus distorting the highs.

B: no filter to cut out frequencies below, say, 70hz or so. Actually, I'm assuming your deck either does not have a high pass filter, or that you aren't using it.

If you hook a decent amp up to your speakers, you'll get two obvious benefits.

A: more power. This will allow you to give your speakers clean, available power at higher volume levels, thus eliminating the need to crank the bass knob quite as much.

B: You'll have a high pass filter to work with. For most budget amps, the high pass filter is fixed at 80 hz. Kencrap amps are fixed at 150hz. The desirable high pass cut off frequency depends on what size your speakers are. If it's a variable high-pass (adjustable), 70 - 75 hz is a pretty good spot if you're using a sub. I'm not using a sub, so I have my high pass filter set at 55hz with 80 watts/channel going to my front speaks. Theoretically, that's supposed to make my speakers "distort". But, they don't.

So, what does a high pass filter do? It cuts off the lower bass frequencies so that your speaks don't have to do what the sub should be doing. This frees them up to play those midrange and upper end frequencies mo betta.

And that is why using an amplifier will not cause your speakers to distort even more than they did when you were using a HU.

And, like someone said earlier, this is assuming that you're using after-market speakers. If not, I highly recommend purchasing some before you purchase an amp. Hope that helps.

ok sorry I'm running eclipse speakers front and rear, eclipse sub, and kenwood sub amp, and rockford fosgate deck. I want to get a diamond audio amp for my 4-channel and a pioneer p6600mp deck.
