Project “Tomahawk”

Ordered up a Mechman alternator. My existing alternator was original to the engine and the regulator was staring to have issues. The mechman amperage at idle is excellent. The goal is to keep alternator voltage at idle vs dipping into battery reserve.

That'll be a nice addition.  

Only thing that worries me about a special part like this is the availability... I guess a stock one would work in a pinch.

That’s right. Since the case and connections are the same, a parts store alternator would work in a pinch. These mechmans are really nice units. High quality bearings and square copper windings.

Audio system under construction at the moment. I’ve long wanted to build enclosures for some compact subs in the b pillars. It’s really an ideal location for them if done right. Started by some careful measuring the other day. Plan is custom enclosures for (2) JL 6.5 W3 subs. Will feed them with either a 3 or 4 channel amp from a customized RX173 head unit with a DSP.

Here’s the beginning of this project. 1/2” birch for the shell which is appropriate for the JL 6.5 subs. Exact dimension tbd but I’m within a narrow range. QTC will be in the .75 range

Will be interested to see how the audio turns out. Assuming amazing as always.

Thanks! I’m also curious to see how it turns out

Some progress made

All the glue is dry now. Going to put in some seam sealer around the inside just for the xtra insurance. For reference, I used 1/2” birch, wood glue, 1.25” cabinet screws and polyfill. Will probably finish them with some black textured bedliner. Next, I’ll cutout the b pillars and measure out the cabinet/edge supports
