is there any other way to remove the head unit without the removal tool?
and do you know where i can get instructions on how to hardwire my rear speakers?

 

What radio is it?

I have a concert radio and i fashioned a flat piece of hard plastic into a key. Simply put; it was thin enough and narrow enough to fit into the slot in the front of the radio then i just chopped of one corner at about a 60* angle and pushed it in. I only made one and pushed it in which released the one side, pulled the radio out slightly then pushed it in the other side and it slid out. Took me 5 mins to make the "key" and 1 minute to remove the radio.

As far as hard wiring the rear speakers, mine had a built in amp which had to be powered. As far as i know the rear speakers are 2 ohms (normal speakers are 4 ohms) which will either damage your H/Unit or your H/Unit will damage the speakers. Just check that out first. Alternately, if you also have a built in amp, and it is the same setup, the plug for the rear speakers has a pin for power - this can be hard wired to the power that is on when the key is in accessory/on position.

I hope i made some sense.

 

it is the concert
and the guy at best buy was telling me how it does have a built in amp

 

go to walmart... yes walmart and to the car audio section and buy the radio removal tools.. you will need to buy 2 boxes.. b/c 4 tools are needed and trust me u will need four to do it easily...

as far as hardwiring ur rear speakers.. give more details hardwire to?? ur new radio? putting in new speakers??

 

do i really need four? the radio only has a slot for 2.
and i wanna hard wire my rear speakers to the headunit (im guessing...since theyre amped they wont play unless i do. or so ive been told)

 

o might be different than what i had.. i had four slots.. if you only have two then nvm.. i feel stupid haha

 

If you have not yet removed the Head Unit, or are still trying to avoid buying the keys... If you happen to have collar stays from a button up shirt. Just the plastic thing that goes in the end of the collar. Use those. You already have them, plus they work fantastic. just my 2 cents.

 

Just go to Walmart and buy the keys. They're about $4. A concert stereo has two thin slots along the bottom. The newer ones have four small square holes. Those are the ones that use the Ford style keys. For a concert headunit, get the flat-blade removal keys listed for Audi. Use them to remove the head unit.

The concert has an amp like any other head unit, but only for the front speakers. The rears are powered by a separate amp mounted on the driver's rear magnet assembly. The head unit puts an amplified signal out to the front speakers, and a line-level signal out to the rear amp, which pumps it up to speaker level for the rear speakers.

 

depending on the radio it may need 4 keys one above the track slect button one above the ff rr button and two on the bottom staright down just get the keys from ebay or something walmart sucks and sucks a lot BE CAREFUL when sliding them in cuz if you jamm them in ur screwed and u jammed the locking mechanism so take the time and do it right and just get the nright tools

 

oh and dont hardwire the rear speakers i work at best buy and im an autotech please listen
