As I said earlier this project went in steps, last night I ran my new speakers only thru my stock system Bose no nav. So dynaudio tweeters, mids and 9" mid base ( not cheap ) hi bandwidth gear in stock location in the front doors. Th sq had issues still no highs or lows the signal must have been eq,ed or some crossovers in the car somewhere but clearly the new drivers weren't getting a full signal. And perhaps due to impedance miss match the center channel was over powering the rest. For the record to get to this point was a lot of work and the results were poor. Today I completed the full install with the JBl MS8 and the Zapco 6/150 and ran the Ms8 it is amazing. The amp an ms8 fit in the spare tire well and live under the carpet. I'll leave the spare cinched down above the carpet. I'll take some pics when I Finnish the clean up work. Finding speakers that match their eq will be finding a needle in a haystack.

 

I just bought the MS-8. Although I haven't had the time to install it, I'm hoping that it will solve my stereo woes.

I'm running Focal 2 ways front and rear, with a boxology box filled with a JL 10W6. Powered by a JL 900/5.

I've had this setup in another vehicle, behind a AVIC Z110BT and it sounded great. I was very disappointed with the sound when this was installed.

Hopefully the MS-8 with make my ears happy.
