Hey guys, I recently ran into some subwoofer installation issues. I havent installed a car stereo in any of my vehicles since high school days, so im a bit rusty.
Either way, a few months ago i picked up a single din Kenwood deck, MRP m500 Alpine amp, TS-SWX251 10" pioneer subwoofer and wiring and all the bits and ends.
So yesterday i got around to installing it. I triple checked everything i could, powered it up, and it sounded alright for the first 20 seconds. Once i turned the master volume up slightly the subwoofer cut out, the amp was still receiving power (blue LED was glowing). I wasnt able to get any signal from the subwoofer until i restarted the head unit. The second time around it did the same thing.
Some of the troubleshooting ive done so far...
-Rewired everything
-checked the ground
-checked the resistance at the ground (indicated next to nothing)
-adjusted all the options i could in head unit's settings
-adjusted the settings on the amp (gain, frequency etc...)
-opened up alpine unit to see if anything is damaged (looked clean)
-Went out and bought a new amp.
After installing the new amp, i was able to generate sound out of the subwoofer and adjust the volume and settings on the headunit without having the subwoofer shut off permanently. But the sound wasnt deep or loud enough, so i adjusted the gain and frequency slightly. after doing so, the amp blew the fuse. I should mention that before and after adjusting the settings it was barely noticeable that there was a subwoofer installed in the vehicle. This amp was only 50 watt underpowered than the alpine.
As oddly as it sounds, im starting to think its the Kenwood deck thats causing all this. Ive read in the other forums that some decks just arent compatible with certain amps, and will force it to go into the protection mode, no matter what type of volume youre trying to pump it at.
On top of all this, ive noticed that my back speakers wont play anything when im using the Bluetooth feature however, AUX and CDs have no issues with my back speakers.
Anyways, im now losing my F***ing mind over this, as ive spent over 7 hours trying to figure this out and i still dont have a solution. Im really hoping someone can suggest something. I already narrowed it down to the fact that either the amp, or the head unit is faulty. i just cant figure out which one it is. Already thinking of going out and just purchasing a Brand New set up, but would like to figure out whats wrong with this one, as it wasnt the cheapest choice of hardware.
