This weekend I installed a sub, Denison, ms8 and arc audio amp.

 

Can you be more specific?
What is a MS8?
Did your car have the OEM Sub box?

The 997TT has been the best OEM Radio I have had to date. What did this improve?

 

wow i tried to upload the pics from my phone i guess only 1 pic uploaded. The JBL MS8 is a sound processor. The car did have the stock Bose sub in the back. What we did is amplified all the speakers then put in the 8" subwoofer in a ported box. EVERYTHING about the system improved. Soundstage, loudness, bass extension. It is much better. The Denison allowed the car to have bluetooth for my phone and bluetooth music streaming.

 

Where did you install the jbl control panel in the car? Did you put it in the glove box? Can you run the jbl without the amp?

 

Yes you can use the amp on the ms8. I don't have the display plugged in. But adding the amp gave me more output and impact.

 

What does the factory amp produce? THe JBL is 18 x 8, - where did you find the greatest improvement in your setup? Did you do yourself?
Thanks
