REwired speakers back to Headunit/ Speakers dont work.

[Nugg32 10+ year member]

So about 4 months ago i bought Two Pioneer TS-d1720c Speakers and i had them wired directly to my headunit, They worked great but everyone told me to buy an aftermarket amp and they will sound a lot better. So about a month later i decided to buy the Alpine MRV-F300 amp to wire my speakers too. I got everything hooked up to the new amp but for some reason i felt like my speakers sound better when they were wired to the headunite instead of the new amp

( //Example// I felt like my bass coming from my speakers(No ****).. sounded a lot fuller when they were wired to my headunite. When i had them wired to my aftermarket amp, The bass was kinda flat)

. I asked 100 questions on a few other audio forums on what could be the problem and even posted exactly how i had everything wired including my placement of the ground wire and how everything was connected to the headunite and battery. Everyone told me it was wired correctly from what they could see and read on the manuals for both the headunite and amp. No one could help me anymore after that. Here we are about 4 months later and i just got a weird feeling and decided to check my wiring again to my amp. I noticed at the bottom of my Amp, there was a lot of corrosion. I decided to just say hell with it and rewire my speakers back to the headunite. My problem now is my Headunite turns on and plays my CD but nothing comes out of the speakers now. I remembered to wire the remote back to the stock amp to my car as well. Any ideas? I just don't really understand why my stock amp in my car worked fine before and now that i rewired it back, It doesn't work.

Check your fuse in fuse panel.

im willing to bet your crossover/s on the alpine amp were not set correctly,... unless of course the added power kicked up the upper frequency response to make it seem as if the mid/bass couldnt keep up with the highs.

those pioneers have a power requirement closer to what the alpine can supply and only a handfull of head units even barely scratch that surface.

Check your fuse in fuse panel.

I've checked them all. Under my steering wheel, under my hood and even the one behind my headunite itself

Did the area you had the amp at get wet or was in a moisture area?

Check your speakers with a ohm reader/DMM to make sure your speakers arent blown.

Other test you can do is get a small drill battery and connect each wire to the positive and negative to see if the speaker moves as this will also test stuck/blown speakers.
