Do different power amps work together?
I am in the process of installing. What I was thinking of doing was using
the receiver (4x21 rms) to power front and rear (or maybe just front) 4" 2-ways. Then run the "Subwoofer pre-out" RCAs to an amp and a subwoofer. (The Subwoofer out has a left and right but I really only wanted one sub, so I am not sure about that). Anyway, my question is: if I get a 100+ watt amp for the sub, won't it be too loud compared to the speakers, which are only on 21 watts? If so, what are some solutions? Thanks in advance |

Basically, you will set the gain on the sub amp to match the volume on your front and rear speakers. So, it should blend in pretty well. Do you know how to set the gain on the amp? -- MaGurk |

no. Actually all I have is the head unit, which has: 4x21 rms, a left and
right RCA pre amp out, and a left and right RCA subwoofer out. I am open to anything not too complicated, though I do want a subwoofer (just one). "MaGurk" wrote in message ...

No, I have looked at some amps but don't remember seeing a gain control. Is
in in the head unit? Let me ask this, would I be wasting money to get a 200 watt amp and subwoofer if I am driving the main speakers with 4x21 watt head unit? If I just used two of the main speakers would I get 2 x 42, making it a little loudes, to match the sub? tom "MaGurk" wrote in message ...

there are so many variables to this. itd take me 300 words to explain
it. from different locations of the speakers to listening to different parts of the music being powered .to itll all blend together anyways. to most want bass louder too. somethings just dont over think it.lol When i open my refrigerator this little lights comes on. do i ask why? no. i just accept it.lol |

If I were to go with only one amp and that too having only 2 channels of
amplification then I would prefer to power the 4inch front speakers first. I may miss the bass but the overall sound of the music would be much better than powering the front from HU. What is the use of sub if there is no mid-bass!! Best would be to have a 4-channel amp and power all 4 speakers from the amp. Leave the sub for now.

Hey Puttster, welcome!
I had a setup much like you're describing for a long time, and was very happy with it! It's an inexpensive introduction to the wonderful world of car audio. As for only using two of the speakers and doubling the power off of the head unit: Not Going To Happen. I don't think ANY head units I've ever seen have bridgeable channels... I would recommend that along with your 4" speakers up front, you get (at the smallest) some 6.5" speakers for the rear of the car somewhere and power them off of the rear channel outputs from the deck. I agree with what Vivek said above, "What is the use of sub if there is no mid-bass!!" Once you have all four speakers inside the car hooked up, a Sub powered by 150 - 200 watts (rms) will be just fine. The gain is also called the 'input level' on some amplifiers. Whatever it's called, I've never seen an amplifier without it, and yes it's a knob on the amp itself. If you have a decent enough head unit, there should also be a subwoofer level control or volume that you can play with too... Hope that helps! ~Mister.Lull puttster wrote: No, I have looked at some amps but don't remember seeing a gain control. Is in in the head unit?

And it might be hiding in a hole or something. Let me ask this, would I be wasting money to get a 200 watt amp and subwoofer if I am driving the main speakers with 4x21 watt head unit? If you plan to upgrade to another amp later for the other speakers, then no. 200 watts is too much for your current setup though. If I just used two of the main speakers would I get 2 x 42, making it a little loudes, to match the sub? The amp in your deck is almost certainly not 2-ohm stable. I bet it works, but clips enough to be pointless. And you may break something. Just invest in another amp when you get a chance. brian |

One more thing... if your head unit has separate subwoofer RCAs, then there should be a way to attenuate the bass from the head unit. You should really set the gain on the amp correctly though. Ideally, you want to use the gain to prevent the sub amp and subs from clipping. brian |

Thanks for all the help folks! Lots of food for thought here, I am glad I
asked. Especially regarding amping. Let me ask another - my HU has four RCA jacks: L&R for speakers and L&R subwoofer. If I use these instead of the wires, does that mean I can only have one pair of speakers (besides the sub)? |

Or am I complicating things by emphasizing the term "Subwoofer out" Maybe
it is not specifically a subwoofer out, maybe it is just a standard rear out. Is this the case? "puttster" wrote in message ... Thanks for all the help folks!

Well it sounds like its a subwoofer output if thats what it says. There should only be one subwoofer channel. The lows on most music is basically mono. You could use either left or right and use it as the mono subwoofer output. It might be easy to measure the voltage betwee the two. There should be no AC voltage it they are subwoofers, but the question is, why would they do that?? greg "puttster" wrote in message .. . Thanks for all the help folks!

Some deck manufacturers make the rear channel pre-amped outputs
optional subwoofer outputs. This is, unfortunately, not the best setup but it works... What this means to you is that you have to choose between a subwoofer or a rear pre-amped channel - you don't have both. ~Mister.Lull GregS wrote: In article , "puttster" wrote: Or am I complicating things by emphasizing the term "Subwoofer out" Maybe it is not specifically a subwoofer out, maybe it is just a standard rear out.

Yes it seems smarter to make it a regular rear pre out and let the amp
perform the task of a low pass filter. Maybe that's what it is and the "subwoofer our" phrase makes better marketing. How would I go about performing an electrical test to see if it was a subwoofer only, before I bought my speakers? I have a multimeter. "Mister.Lull" wrote in message ups.com...

How would I go about performing an electrical test to see if it was a subwoofer only, before I bought my speakers? I have a multimeter. 5 to 1 volt or so AC will indicate a stereo signal. Zero if mono. If you had an auxillary amplifier or one of those little portable speaker adaptors, you could somehow feed the preout into it and listen. Even a home stereo could be used. greg "Mister.Lull" wrote in message oups.com... Some deck manufacturers make the rear channel pre-amped outputs optional subwoofer outputs.
