Mono block vs 4 channel amp?

Question

I currently have a 4 channel amp that is bridged and is running my subwoofer. Will a monoblock increase the sound quality or will it just let the sub push harder? The sub is 1000W peak and the 4 channel is 50W RMS per channel.

Answer 1

well no it probably wont make much different as long as the amp says how much wattage it has in a bridged mode to one sub and its rms matches your subs its all the same

to increase maximum power try to wire your amp at 2 ohms. its easier to do this if you have a dual voice coil sub

Answer 2

From your question, I understand you have one subwoofer, right?  Since the sub is 1000 watts peak, I'm guessing it's less then 500 rms, which is the number that matters.  If your 4 channel amp is 50 rms per channel, I'm guessing it's about 100rms bridged.  So, you've got roughly 100 wrms going into a 500 wrms sub.  Which, is fine if it's loud enough for you and doing what you want it to.  Judging from the actual question, "Will a mono block increase the sound quality or will it just let the sub push harder," you're looking for better sound quality.  

First let me clarify something for you.  Amps don't "let" the subs "push" at all.  A sub is simply an electrodynamic motor system.  It receives an alternating current signal from an amplifier and turns it  into analog audible signal that you can hear.  Your entire stereo system is one large electronic circuit of which the subwoofer is just a piece of the puzzle.

So to try to answer your question, a monoblock, if more powerful then the power being put out for your four channel now, may improve the sound quality of your system.  However, sound quality, as subjective as it is, will be altered by what subwoofer you use, the enclosure you're using, the vehicle you have it in, along with several other much more minuscule factors.  

Knowing very little about your system, you or your listening preferences, I'd suggest getting a mono block to power your sub and use your four channel amp to power your main speakers in the car.

like air forceyooper answered

what are you looking for?

If the bass in your sound is good for you dont put a mono block amp to push your sub harder... cuz the sub will be more stronger! you will hear it more!

if u are looking for more loudness then put the amp ;)

if it was my sound I put the amp to shout out the music!

Answer 4

u will be fine with the 4 channel amp...mono blocks r better for subs cause they can handle power beter in all areas but u will be fine..as long as ur amps rms matches up to ur subs at the right ohm

Answer 5

the mono will push the sub more and the sound should improve
