New head unit issues
 

I had an alpine ___ installed less than 12 hours ago in stock Bose system. I have lost ALL bass (stock subs) and I do mean all. Stock HU with cassette was better than this bull $hit. The alpine (will give exact # I'm the morning) is not working with the back USB as well. Recommendations? I will be taking the car back tomorrow, as it is rediculous I had better sound with the stock unit

Am I the only one or any recommendations on what to tell the installers to do (it was his first Infiniti)

after I installed my DD, I had a very poor sound quality. After some research, I was told that the bose system is not compatible with my Eclipse DD and so I ended up changing all the speakers, added two alpine pdx amps (one for the speakers and one for the JL sub), added a 12' JL audio sub and rewired everything. Then I noticed the difference between a bose and my current set up. No matter how loud, the sound stay clear. BUT it will cost you big $

I used to be a car audio installer and my initial guess is they did not hook up the amp turn on wire. this would be the blue/white wire that needs to go to the blue wire on the nissan harness. I have never run across a nissan with bose that needed an amp bypass which is what your alternative is!

I do not want to spen more money on the car that I'm going to be selling. I'll take it back tomorrow and have them find out if they connected it.

It also is not nearly as loud as stock. Idk the guy installing it told me he's never done an infiniti before :/

You ever find out what was wrong? Same issue I have and same reason the installer gave me too.

You have an stock amp in trunk for speakers may have blown

the short answer is you need PAC ROEM-NIS2 if your reusing the stock bose amp and speakers
