Sub not working after installing the jensen vm9022 deck
We installed the vm9022 Jensen radio deck into a 2003 Tiburon. The original radio was an Infinity premium sound system with amp and sub-woofer. After installing the new radio deck we are not getting sound out of the sub. We have cheked and rechecked the wiring and all seems correct. I am guessing that the amp is not getting enough power to turn it on. With the amp buried in behind the rear side panels it is hard to verify that the amp is getting powered on. If we put the old radio back in the sub works again. What do I need to do or check to get the sub to work again?

Re: sub not working after installing the jensen vm9022...
Reinstall the factory radio use a digital volt meter to see witch wire supplies voltage when radio is turned on and off, note placement on harness then verify this wire is hooked up on the output side aftermarket harness you may have to jump it to get the maps to turn on. tip you can carefully pull unused wire from harness example (dimmer wire orange white) and move it to the position needed to keep it a clean install .

I have the exact same problem with the exact same stereo. I started by removing the in-line AM/FM/VHF Separator and connecting the antenna directly to the stereo. The static/popping/fade-out continued. Today I swapped to a new antenna, but it did not help. I swapped back to the original antenna and for a brief while, I had good reception. The I went to coil the excess antenna cable and the static/popping/fade-out resumed. I have narrowed it down to either the antenna connector coming out of the back of the stereo or an internal circuit. Either way, it does not look like a do-it-yourself fix.

order from jensen or go to a local audio store, ie sound creations,
or a store that installs car stereos, I have had pretty good luck with circut city, best buy is a bit cheaper, but then again you get what you pay for.
was the unit new or was it a demo? if it was new in a box I would take it back to where you purchased it from and exchange it. some decks the code can be reset such as the case you bought a used car ect., and others you need to replace the code IC in either case you will need to contact jensen custmer service or get the technical schmatic.
good luck stereo tech
