Current setup JBL MS-8
running Volvo mw162gt from a
JL jx360/4 which is approx 70w with minimal gain.
Would I benefit giving them more power?
I have a PPI black ice 800.4
130x4 @4ohm.
How much power can the mw162gt take?
Doors have been treated and sealed but it was years ago, I’ll probably go through and recheck everything again.

If it doesn't sound good at 1 watt its not going to sound good at any watt.
70 watts is plenty.
What is it you're trying to achieve??

More mid bass,
The ms-8 is finicky and I’m happy with its current tune. Just seems like it needs more power.

Power may not be the problem. Proper integration from sub bass to mid bass plays a big part in making the mid bass have presents. Have you RTA'ed the vehicle from the listing position? You may have a null in the mid bass frequency range. Power will not help that... very rarely is lack of wattage the problem.

I haven’t recently RTA’d , and when I did it was with a Dayton imm-6 and iPad.

Unfortunately the MS8 Eq’s and TA automatically, you only have adjustments to the 31 band eq after the tune.

I’ve kicked around the idea of replacing the ms8 with something like a helix or other dsp.

I can take another RTA later today and screen shot it.

What does your sub bass look like? What crossovers settings are you running on the sub stage and midbass?
Good midbass is all about crossover settings and phasing.

I would take reading of left midbass, right midbass, the them combined. Then again with midbass and sub stage together.

Ms8 crossovers are
Subsonic 30hz (subs are ib in trunk )
Mid/sub frequency is 80 [email protected] db.
All crossovers are defeated at amps.

Ok here’s are some quick measurements. This is me sitting in the driver’s seat.
All measurements are 30 sec averages using pink noise.

Here are the ms8 eq settings
They are not individual output or L/R adjustable.

The ms8 does an autotune, you wear binaural headphones and the unit completes a series of sweeps.
This is where it does time alignment, frequency response and level.
How does auto tune differ from "time alignment, frequency response and level"?
What else is added?

It doesn’t differ. I was just pointing out I don’t have individual control of the speakers.
I wasn’t quite sure what MichaelEvanchuk was asking.

The only thing I can think of that’s added is phase
