ok i have a 2000 mitsubishi eclipse gt witht the upgraded infinity sound system. it comes with an amp, but my stock 6x9 were blown so i bought polk momos. those speakers are the only after market mods i have done. now the speakers work but hardly any sound comes out of them. the bass on the momo seem less then my stock speakers and i just dont understand why.... please does ne one hav any suggestions to what the problem cud be.

im not familiar with the stock amp that comes with the infinity system but it sounds like the settings may be off. did you do anything other than change out the speakers when you installed?

no all i did was change them. should there be more work done

would you happen to know the impedence(what ohm?) of the infinity speakers and the impedence of the new speakers?

The stock infinity system is a 4 ohm system, if you bought aftermarket speakers that arnt 4 ohm, well they arnt going to work well and hardly any sound will come out. Your polks you bought are probably 8 ohm

thats what i was thinking^^^

well damn i thought u guys figured it all out until i looked at the box.

its 4ohms
100 watts rms
300 watts peak
91db
33hz-25khz
with these stats ud think they wud hit hard

now wat :(

go through and check the speaker wire and make sure everything is connected properly then check the speaker wire going into the amp make sure its also properly connected.

sometimes when you replace speakers you accidently pull a wire and it comes loose from the amp or isnt fully connected

i just checked all the wires n everything is fine so maybe it is the amp. but its under my passenger seat n i dont know how to get to it

if everything is connected properly between the amp and speakers then it is probably the voltage. Im not familiar with how to take out the infinity amp but next you should look to see where the amp is grounded and make sure that there is maximum surface area between the car chassis and the ground wire. do the same for the power wire also.

You guys are making it alot harder than it is.

Its because the speakers that come stock are easier to drive, they are a paper cone and take a different amount of power to get them moving fully than an aftermarket speaker.

think of it this way, if you buy a 1000w RMS sub and power it with a 250w RMS amp, it will sound weak. But if you get a 300w RMS sub and power it with 250w RMS, it will sound explosive. It is because it only takes 300w of power to move that sub, whereas it takes 1000w to get the other sub moving to its full potential.

well if that is the case then that infinity amp must be a POS. I just figured it could at least do 75x2 but i guess not. in that case you will need a better amp

now guys i just wanna say thanks for all the help, but one question with wat ur saying bob, that sounds very possible almost common sense. but wudnt it do that to both the speakers. one sounds great the other however sounds like ur saying not being put to its full potential......

holy sh*t guys im so sorry for sum stupid reason i didnt say its only one speaker that doesnt sound as loud as the other, cud it just be a bad speaker

are you sure the old speakers are blown? sounds more like an amp problem. but that still doesnt explain why one channel works and the other doesn't

U know i dont want yall to think im an **** n you guys have been lots of help. but now its coming together... i thought the right 6x9 speaker was blown so i replaced them, now the right side speaker still doesnt work as well as the left. so it has to be the amp connection right? as u can easily tell im new at this, but im sick of paying someone to do the job, cuz in the past i have paid for bad installations. but now i gues the question is how do i get to the amp its under the passenger seat.... i cannot figure it out, n cannot find ne info on how to either

if your going to get a new amp(don't know if you should before you know what the problem is) you don't have to take out the amp. just take out the wires and put them into a new amp.

this place is really good for helping on installation. click on the videos on how to install speakers and make sure you did all that was inculded in the video. also have videos on how to install amps/subs etc... http://www.crutchfield.com/S-MZmLsaduTY2/app/car/mycar.aspx

before you do anyting, take out a 6x9, and run like 2 ft of cable from the amp, test the speaker there, maybe you just have a bad wire.

On my 95 eclipse there is just 4 bolts that hold the seat on and the amp is right under it, i dont know if it is the same on yours.

But when you do get to it and if its a 2 channel amp you can always run wires from the left 6x9(the good one) to the 2nd channel for the right speaker and if it sounds weak then you know that the 2nd channel is blown or not working properly.

I had the same problem with one of my aftermarket amps and thats how i tested it.
