Mach 1
Just went thru your thread. Having did the audio in my Mach 1, I’m considering a Procharger like you have done.

I wanted to have my mid bass 6.5 inch woofer speakers exposed like yours but you said you weren’t satisfied with the way they turned out.

What do you think about removing grills on the Mid?

I’m also considering a Procharger after having come to a stopping point on my car audio. How has your setup holding up? How much power does it make?

We have similar taste. I even have Polk RTi A9’s and A7’s for my home theater with a Pioneer Elite SC-35 running separate amps.

Hey guys, I posted most of this in my build log already. But I figured I would make a separate thread in the audio section after getting inspired by a few other member's threads.

I've had several other systems ranging from 300 to 3000W, but this one takes the cake. Largest and craziest system I've ever done.
This thread/post will be very long and picture heavy, feel free to browse through, hopefully it gives someone the inspiration to tackle something similar :thumbsup:

Since this post I have downsized the system to 4500W.

Details on Page 3 and a refresh on page 4.


Specs/Components...

~8000W RMS
Subwoofers:
2 x 12" Fi Audio SP4v2
Front Speakers: Hertz Millie Legend Active 3 Ways (Woofer & Mid in door, Tweeter in pillar)
Rear Speakers: Hertz Millie Pro Coaxial
Subwoofer Amps: 2 x Rockford Fosgate T2500-1bdcp (Rated @ ~3500W each)
Speaker Amp 1: Rockford Fosgate T600-4 (Front & Rear woofers)
Speaker Amp 2: Rockford Fosgate P400X4 (Front mids and tweeters)
Sound Processor: Helix DSP Pro
Enclosure: Custom Built Ported Subwoofer Box (Tuned @ 32hz / 5.7cu.ft. Gross / 3.5cu.ft. Net / Birch Plywood)
Cooling: Four 70mm Fans mounted above amps
Vibration Damper: Sound Deadener Showdown CLD Tiles (used in doors, trunk, and trunk lid)

Electrical Upgrades:
370A Singer Alternator
XS Power D4700 AGM Front Battery
XS Power 500F Supercap Bank
KnuKonceptz 1/0 AWG OFC Power/Ground
Two 1/0 Power & Two 1/0 Ground from front to rear (ran under car in ENT electrical conduit)
One 1/0 Power run from alternator to battery
Custom made battery terminals


First thing first, the final product.

The box does look crooked in the photos so I believe there is a little room for it to move when the seats are down. However I made sure the back seat is above the box/board so that it cant go past it.

As pictured you can see I used several brackets to hold everything together. There are straight brackets holding the amp walls to the box in the rear, and brackets holding the front of the amp boards to the board in front of the box, which is then L bracketed to the box. Also L brackets on the top of the boards and to the box. Keeps everything nice and secure and holds everything together. Feels very sturdy and all one piece. The left back seat goes back, the right one does not since the two amps on that side are longer. I may try to make a notch in the seat for the amp corner to sit in so I have the ability to close the seat. I usually ride with it down anyway though.

The gap in the back of the trunk, and the cutouts are for my upcoming methanol injection tank. Left cutout is for the hose to run through and allows some access to the pump, right cutout is for the wires. I may have to move the box slightly forward to fit the tank and condense the wires to the right side. This is coming soon.

Fuse holders for the driver-side amps are mounted on the board in front of the box, the passenger side amps fuses are near the battery. I would have rathered put them all out of sight but there was not enough space to do it any other way. Same with the terminals on the front of the subwoofer box. Sound processor is mounted on the backside of the driver-side amp board.

Some photos of the amps before the box was put in...

These are pics I snapped while in the process of installing so things look a bit neater now.

Nice!

I put a foam ring around the speaker cutout to clean it up some, I'm not fully happy with it but it's ok. I'm not sure if the mid is perfectly lined up or not but not worth it IMO to find out lol.

I love the procharger. Making 840whp. Everything I've done with it is in my main build log.

Thanks! The bass is pretty intense especially since the interior is so small the woofer is real close to you. Have to spend some time retuning it now as I also removed the factory EQ with forscan, which I neglected to do before. Yep from Jersey (unfortunately lol)

What numbers did you have on yours that removed the factory eq and what section?
