Ruh Roh!!! Just got the 4th Brutus in!!

Had to re-wire everything. Pulled 6 of the 12 subs to get access to the inside of the box. Then rewired them all. I didn't get photos of that... not like it is interesting anyway. So- 3 subs per amp. Makes @1.33 ohm load (reads more like 1.4 / 1.5 ohms). That part was bad enough. Then Pulled the Amp Board for the mids and processors, pulled the sub amps, then added some wood to the box so all 4 amps could be mounted. Wired that up, tidied up wires (though it may not look it from the pictures), then cleaned up the back of the Amp Board for the mids and processors. Put that back in and wired all 10 channels back (I think it is 10... it is a lot. Everything is dedicated active xover'd- other than the 2" A-Pillar pods that are Active + Bandpass Passive).

But bla, bla, bla!!! You guys want pictures!! :D

This happened while re-wiring the subs. Aren't magnets cool? hehe

What a mess...

All together.

Wood fabbed in for the amps.

Three & Four.

More wires going in.

Even more wires & the EQ for the sub (sorry for the blurry pic)

This is how I do cheap RCA junction boxes. It was a 5 channel splitter that the buttons broke on. So- I cut it up, soldered up all the Lefts and all the Rights, then the input goes in the middle. The outputs are equidistant from there. I checked it with the multimeter. Like no drop- cleaner than Y-Splitters. And why not use the output on the amps and daisy chain them? Meh... Just didn't like that idea.

Yeah, I know what it looks like.... you can't see from this photo, but now there are like a million zip ties and miles of wire loom on top of this.

And everything actually came on just like it was supposed to! Thank Goodness for Multimeters and the Continuity selection.

Pay absolutely no attention to 11.4 volts. It means nothing- except that I continually wreck my battery. LOL

Some night photos perhaps?

Now, I know I have some tuning to do, but.... HOLY CRAP. Yeah, so I added one amp. But since I went from 1 ohm on each of the 3 to 1.33 (or so) on each of the 4, I really thought that it would pretty much wash out. Nope. I was wrong. It is louder. Much Louder. And way punchier too. I don't know if that comes from more control from the amps being at a higher impedance or what, but there is a big difference.

I couldn't get too crazy with it, as it was dark by the time I got done and back home from dinner (today was wife and my 10th Anniversary!!). So- tomorrow- hopefully some fun will ensue. It is amazing what level of bass someone can get used to. I've gotten used to a certain amount of bass at certain volume levels. So much for that. Before where 28 was getting it pretty good... it seems that loud at, um... 16. :D

Now... if within 2 weeks I can get my second 220 amp alternator in, I think I will be doing pretty good. Gotta' be respectable at Scrapin' the Coast in Biloxi, MS! :D

Thanks man! I appreciate it.

Yeah- wire overload for sure. But I keep adding one more thing and one more thing- until I am out of time, money, or room.

Yeah- I just let this crap get waaaay out of hand. I will be the first to admit it. I swear, next time- I'm starting out with a small vehicle. That way I can't get this crazy with it. :D

SQ! I wanna' do SQ on the next ride (hoping there is one, of course). :D

Maybe that is it.... Matt, you are going to have to help my feeble mind understand that one. So, though my impedance went up, because I use fewer subs per amp- impedance rise goes down? Cool- I will take it! haha.

Where have you been bruh?!?! You gonna' make it to Scrapin' in 2 weeks? Seems like a butt load of SMD folks are going this year.
