3.5" dash Speaker installed!


The blown Stock speaker was bugging me so i disconnected it. But the system just didnt sound right after that so i installed this

It sounds pretty good it has a little more quality all around

it is a Polk audio DXI 350 marine speaker 35W rms 105W peak 4ohms (yes i know the stock speaker is 2 ohms but this speaker is so beefy that it should be able to handling a 2 ohm load no prob)

Thats a good speaker to handle the mids that speaker is going to get. good election.

I believe it would be correct to say that a 4 ohm speaker seeing the same signal (volts) is going to only see 1/2 the watts that a 2 ohm speaker would see - i.e., will last longer but won't be as loud? (P=V^2/R)

It actually wont honestly matter that much on the ohm load.

The only time that matters is when you take an amp into account and how you wire that amp up.
Since its the stock amp and no extra wiring is required, I wouldnt worry about it

...but it is a fact that that speaker operating on the same wires/signal levels will be seeing only 1/2 the power. Not going to hurt anything and may not be that noticeable, but it is less audio power out of that speaker. One thing for sure is that it won't be *more* stressful on the higher ohm speaker as Alex was implying - it will be less stress (assuming signal level is not adjusted). That was my main point.

I'm pretty sure that the speaker would be a little bit quieter, but I do agree that the power difference wouldn't be AS noticeable. Reason for my thought is that the amperage difference would be most noticeable when your trying to power a large speaker or sub operating at low frequencies where as the 3 1/2" speaker would be working at the mid - high frequencies.

It doesnt matter what ohm the speaker takes.

If its getting a 2ohm load from the amp, then it is still getting the same amount of power as a 2ohm speaker would.

How is it getting a 2 ohm "load" if the speaker is 4 ohm? I believe the speaker in this case is the load! Please explain.

B/c you wire the 4ohm speaker (I know you can on that particular model) to a 2ohm load. Not hard to do.

Exactly the same way you wire two 4ohm subs down to a 2ohm load to pull the most power from an amp.

If you don wire it down to a 2ohm load, then

Ronbo is correct. The speaker IS the load. The amplifier is made to work most efficiently when operating with 2 ohm loads (speakers). When using 4 ohm speakers, it would take twice as much voltage to push the same amount of current through the speakers compared to the 2 ohm speakers.

I don't know the exact voltage or current the amplifiers are running at, but for example, if an amplifier operated at 12 volts with a 2 ohm speaker, it would put out 6 ampheres (or 72 watts).

Using the same amplifier, operating at 12 volts with a 4 ohm speaker, it would put out 3 ampheres (or 36 watts).

Ben...you need to brush up on your electronics.

The example you're referring to above regarding 2x 4 ohm subs is putting them in Parallel which presents a 2 ohm load to the amplifier.

In this case it's a single 4 ohm speaker by itself. It presents a 4 ohm load to the amp. If there were 2x 4 ohm dash speakers wired in parallel..then yes it would present a 2 ohm load to the amp.

That's why I included the formula at the end of the earlier post:

The output of the amp is essentially a certain voltage amplitude proportional to the demodulated audio signal. If the amp was designed to put out *current* proportional to the audio signal, then a different formula would apply: (P=I^2xR) *Then* the 4 ohm speaker would actually be sucking up *more* power than the 2 ohmer. Kind of a brain teaser, but it's da twoof.

True.

But refer back to my post. You dont wire it up as one speaker.
If you want a 2 ohm load (which is what I thought the OP was asking about so as to get more power) then you can do that by wiring it up with either one of your front midwoofers.
I dont understand the argument. I said earlier that if you left it alone, no big deal, you get half power.
But you CAN get the full 2ohm power going to that speaker if you wanted to. Isnt that what the OP asked? IDK, maybe I misunderstood.

Now how exactly you would tie that in with the stock amp, I really dont know off the top of my head. Ive never studied the stock amps to know exactly which wire goes to which speakers and exactly how many watts are on each independent channel. But I dont see why you couldnt do it with the stock amp, since I know (from personal experience) that you can with aftermarket amps.

Since I have an aftermarket 4-chan, I just wired it in with my midwoofers since I dont have a true "center" channel. Did the same on the back two 3" I put in the doors (300M Interior) by tying them into my rear deck speakers.
