Hey guys, have had quite a few people message me about my setup for the Q50.

Alpine 12" Type R's Link Alpine Electronics of America, Inc.

I suggest buying these off Amazon.

These two subs are being ran by a 1500 Watt Rockford Fosgate Amp. I chose this brand because they are local to Phoenix, and I got a smoking deal on them.

POWER Amplifiers - T1500-1bdCP - Rockford Fosgate®

The enclosure is a custom built box. You will not be able to open the rear opening in the seats as the amp is mounted on the back, and there are a ton of wires being ran back there. Anyways if you have questions let me know, here are the pics.

lots of cuts in the trunk

and more cuts

Very nice install. I really miss car audio. But, I don't think I going to modify mine anything soon

Nice set up - is it sealed or ported? Any issues on the stock electric running 1500W RMS?

Its a sealed enclosure. No problems whatsoever with any of the electric system thus far, and have had them running for about two months now.

You did the subwoofers only? I assume you also have it receiving signal from the speaker back there....?

Hows the sound quality from the whole setup? Any rattling?

To improve sound quality, you can always consider getting DynaMat and wrap the whole inside of the trunk with it.

Yes I did subs only, I will be installing an amp to run all the stock door speakers until they blow and then will replace the speakers themselves. Sound quality is top notch, obviously with two 12s you don't need to turn the bass knob up all the way.

I actually did have a major rattle problem, I found the source to be the rear window brake light was coming in contact with the window itself. So I put a thin layer of foam surrounding it. Now there is no rattle whatsoever

Are you getting the signal for the subs from the rear speaker?
Also, how are you going to power the stock speakers with your own amp? arent they already controlled by their own BOSE amps? not sure if you will be able to run speaker wires to them since its probably a different type of connector....

 

[Jason91]

To be honest I'm not sure how my guy installed it so I couldn't give you an answer on where the subs are receiving signal from, I will ask him when he installs my amp for the door speakers and let you know. As for the speakers, I don't have the Bose system or this upgrade probably wouldn't have been money well spent. The speakers are being ran off the headunit.

He hasn't posted here in over 6 years. You'll probably won't get a response from him.
