need help wiring my amp amplifier front door speakers 6x9 rear parcel shelf two 2 sub woofers and my head unit?
i haven't bought anything yet because i need your help to inform me what would work.Now i want to run 2 powerful subwoofers rated at about 800watts each and, if its possible, run 2 parcel shelf 6x9s, that have an average Amp Amplifier power rating, off of the same amplifier.Also i want to run 2 front door speakers off of my head unit ( and possibly 2 tweeters).So what i need to know for this setup to work is:1. how many RCA output ports does my head unit need2. how to wire my front door speakers to my head unit3. what power does the amp need to be putting out4. how many RCA input ports does my amp need5. what i need to be able to add tweeters along with the door speakers, i.e crossover filters, secondary wiring.6. how to wire my 6x9s to the same amp but still have them working at the optimum level 7. how many channels my amp needsAnyone that can help is a legend. Cheers

It is possible but you need a hefty power supply.A 13.8 volt DC 25 ampere bench-top power supply will push a 350 watt RMS total system at the cost of about $100 just for the supply.
There is no need for a 200 amp cable. most of the time 75 to 100 amps is more than enough. Just go to the local car audio store and pick up a amp kit. (Depending on amp size depends on price) The local Wal-Mart sales them as well. You’ll spend between $25-$100 for a good amp kit.

a two channel amplifier will run in stereo, seperating the left and right channels so that you hear them reproduced correctly and accordingly(mostly noticed in a recording from a live performance). you will want to run your subwoofers in a mono configuration. you want both subs producing the same sound at the same time or you get wave cancellation. also, you won’t be able to hear the difference between lt & rt from where the subs are placed and being in the same box. most, if not all, stereo (2 ch) amplifiers have a mono or bridged option. this combines the output of lt & rt channels into a single channel, doubling (effectively) the output.
Not advisable. If you bypassed the “cheap” amp as you put it, you would have more power, but your speakers would probably not be able to handle it safely.Anything that is around a bunch of kids who are drunk will probably be destroyed by drinks spilling, by people falling into it, you know what I mean. Furthermore, if you want to invite the cops to your drunken party, then the easiest way to get them there is to make a lot of noise. They love coming to parties like this!I would rethink the whole idea. Somebody might end up to be very sorry for this party!
If the sub is 2000 W max then no… as RMS power is generally half of the max…If it is 2000 RMS, then yes it is being underpowered.. ALOT !!
Yes of course!The voltage drop at the input (diode) has to be greater than 0.7V to let the current flowing through it. For lower voltages there is no current going through the resistor, so its voltage drop is 0V and the output voltage is thus 0V
it might not damage anything immediately, but the lifespan of ur equipment might be reduced
U never go wrong with Fosgate bro
HelloFirst question do you have a 2 Power supply radio?Red Fused and switched,Yellow No Fuse and Permanent.With only 1 Earth?If so, and most are now (coded) then the best you will do is to insert a 4 pin Relay The relay pins are normally marked as 30 85 86 87.Red power wire between the fuse and radio connects to 30Earth connects to 87New power supply wire (Fused) connects to 86Wire from Amp connect to 87.Amp Earth connects to good groundIf you mount the Relay in the Dash remember to leave the In-Line Fuse where you can get to it.This will mean that your Amp will turn On/Off with your ignition .Before the 2nd Power supply became common you could have inserted the Relay pin 30 on the earth wire and left the Amp turned on and it would turn On/Off with the radio.Andy C
I would recommend using an electronic parts supplier warehouse because you can get a 2uF cap for $15 instead of paying the ridiculous amounts that “name brand” suppliers like Kenwood and MTX ask for. Those things can run over $100. And all they are is a sticker stuck on the same cap you can get direct.
The amp head is only a power and processing part of an amp. In order to get any sound you need an instrument grade speaker cabinet to plug into your amp head. Those can cost quite a bit too.
Only if the home stereo has a phono input. That will have a built in phono pre-amp.
Okay, your owners manual says maximum input current is 20 amps. There is the answer. The fuse should be 20 amps.Problem solved.The power ratings actually call for more, but those ratings are what they call peak power, not RMS power. So the 20 amp fuse sounds right to me. I would use a 20 amp 12 volt slow blow fuse.
Yes it canThe fuse is there to stop your amp drawing excess current and causing damage to its self. Excess current is usually caused by a short circuit in the system.So yes it can work, if you short across the fuse holder, but you will be removing the safety system and it could result in blowing up your amp.
The instrumentation amplifier is similar in some ways but instead of having a very high gain, it has a defined gain that is programmed by the user. If it was set to Av = 1000 or more it may appear to work, but would be inaccurate. The open loop gain of an op amp is more like 1,000,000 but not defined.An instrumentation amplifier can be used in a different way. It measures the voltage across a resistor used to load the photo-diode. The resistor is chosen so that with full scale illumination of the photo diode there will be 10 or 20mV across it. WIth less load (resistor too high) the voltage will be higher, but the photo-diode output will be more compressed (non linear as the illumination increases). This may be useful too. The resistor and the + and – inputs of the amplifier are connected across the photo diode. There must be a path to common for the bias current of the inputs. Ideally have two equal resistors in series for the load, and connect the center point to common through another resistor from 10K to 1M. An instrumentation amplifier usually has a reference connection, connect this to common too. These are more expensive, but have some advantages in that a balanced differential input can be used without loading the signal source. Common mode voltages are suppressed, it only measures the difference between the two inputs. A cable of a few meters length becomes practical.The resistor. Measure the short circuit current of the photo diode with maximum or full scale illumination.Calculate the resistor from ohms law. Use this current and 10mV. Thus for 1mA the resistor is 0.01V / 0.001A = 10 ohms. Use 2 x 4.7 ohms in series to provide a center tap. Now set the gain of the amplifier to give full scale voltage with 10mV input. You get the formula for calculating the gain from the data sheet.
