When I bought my truck it had all stock speakers. I replaced the door speakers because I couldn't hear them unless I put my ear to the speakers, so I bought new speakers the same issue. The new speakers came with an amp but I haven't installed it yet. I am wondering if that will fix my issue or do I have to buy a new stereo deck (I would like to keep the factory one)?

Which radio do you have? Are all the speakers quiet?

It would be really unlikely for more than one speaker to (1.) go bad at the same time, and (2.) have exactly the same problem as the other bad one(s).

Your profile doesn't say which year or model you have, but here's the radio wiring diagram for 2011 and 2012 models:

Note that there isn't any single wire in the harness that could fail which would result in more than one speaker not working - which seems to indicate that the harness isn't your problem.

As Wet Dog implied, if some of your speakers still work (and you can also still faintly hear the "bad" ones), maybe you've just got the fader misadjusted.

I have a 2013 SV. The front tweeters are loud and work properly. The new speakers do the same as the old ones. I took it to a audio shop they looked at it and told me I just need to have a stereo with an amp built in, so I was thinking why couldn't I just put a amp in it instead of replacing the factory speakers.

I have messed with the fade, balance and all that stuff....its not getting louder. I'm going to take it to get looked at in a few weeks as soon as my 50"curved lightbar gets in ....so they can put everything in and fix the speakers all at once.

Because your factory head unit can't communicate with an amp. The amp gets its input via RCA cables, and your headunit doesn't have RCA preouts to plug them into to communicate the sound to the amp, which then sends power to the speakers. To use an amp you need an aftermarket headunit. You can get away with a headunit and no amp; your (aftermarket) speakers will be underpowered but you should get full sound.

My guess is that, assuming everything is set properly, your radio is crapping out.

You can if you get an amp with the right features (see my other comment below)... but if you pump more power into the factory speakers you'll most likely blow them, because the factory speakers are only rated to 3-watts.

Not entirely true... you can use an aftermarket amp along with the OEM head unit if the aftermarket amp has speaker-level inputs, or if you use a line-level converter between the amp and OEM head unit's speaker outputs.

I did go with a 4 channel amp to power the door speakers then the audio place told me they did something with the tweeters to they would not be powered by the amp. I am pretty happy I got what I was looking for without getting rid of the stock stereo.
