Also, get a real ground distribution block rather than stacking all those lugs on a single post. I recommend limiting three lugs per post maximum even with a large battery 5/16" post or a 5/16" or...

The visual reference could be deceiving but I see several concerns.
Is that really 4-gauge cable feeding all amplifiers individually?
Is that the 'funny' cooper-clad aluminum alloy wire or all...

Your 800.4 should be in the highpass mode.
Temporarily remove the turn-on lead from the sub amp (rendering it inoperative) and check to see if the 800.4 behavior changes when driven hard with the...

I'm very interested in knowing EXACTLY how members of the 12volt community have used a resistor in this particular application?

You can't run just one of two voice coils because it changes the parameters....changes how the woofer operates, especially related to a given enclosure.

You can run the voice coils in series,...

The two 10-inch option should be out because you do not want to split sub locations unless they are perfectly symmetrical in all aspects....same loading, same depth, same orientation, etc. Terrible...

Small 6.5" and 8" usually need to have slightly larger motors to be relevant in sensitivity. But large motors and larger motor force generally means a higher Q and a higher resonance. The narrow...

Certainly three of four tightly collected and beefy 6.5" with that motor to mass ratio would be incredibly responsive with some amazing attack. I would think this would be even more impressive in a...

Because Wetsounds says their BT receiving antenna is located in the face panel I would think high and tight under the dash is the best location.

Actually, this same Exile BT subject has come up in threads on at least two other wake forums in the past few days. I haven't made a comment on those.

We've heard this song and dance so many times. Marketing hype. So I don't know what I can and cannot trust. I do know this from the past.

Past a certain point the voltage output on a BT module shouldn't make any SQ difference what so ever. That seems like a smoke screen just to get the appearance of an advantage over the competition. ...
