Gadabout's Audio Build

Plans (Subject to change)
Amps: NVX JAD1200.1 & NVX JAD800.4
Sub: NVX VCW104
Speakers: Image Dynamics CTX-6.5cs (Fronts) & Alpine SPR-68 (Rears)
Wiring: NVX Power/Ground/RCAs/Speaker-Wire
Power Supply: XS Power D1200 (Main) & XS Power XP750 (Auxiliary)
Source: Sony XAV602BT

So far the Sub & Monoblock are in. Been in for a weeks, and I'm loving it. That is what is pictured below. The Big 3 Upgrade has been in for months. The XS Power D1200 will be in next week, which should do away with the very-minor dimming headlights. Following the Battery will be the Four Channel install, in a few weeks.

Running the NVX JAD1200.1 to the VCW104; 800w RMS @ 2ohms , dyno shows up to 1000w RMS @ 2ohms @ 14.3v

Fuse/Fuse-Holder from Alt straight to Batt. 0 Gauge, part of Big 3 Upgrade.


T-Spec Circuit Breaker, 4 Gauge OFC Power for amp.




Good ol' Bottle Caps for Spacers Trick.




.....to be continued.....

Thanx for the subs guys =]

Just a few more details, since I got inboxed with a question;

My '06 is an AutoTrans so I used the deadplate -where a clutch pedal Would go - to run the 4gauge through the firewall. The Amp Kit I used came with a small grommet, so no concerns about leaks and such.

My crossover settings are;
@the Headunit: LPF for the Sub at 120hz . HPF for the door speakers at 120hz . I forget what the 'curve' is.
@the monoblock*: The LPF at ~120hz. Subsonic at ~35hz .

I set my gain by using Ohms Law & A Multimeter**; So the square root of 800w*2ohms = 40 . I'm aware that this isn't ideal, and that the amp may be doing more than 800w and blah blah blah blah, but I didn't want to do it by ear.


*I don't have a Crossover Calibrator so these figures are just Eyeballed, until I get my hands on an SMD CC-1.
**Only temporary until I get an SMD DD-1

You can also drill a hole right above that as well. I did to run my power wire and my wide band in the SVT.


I don't blame your for not tuning by ear lol but it will definitely help with getting the most out of it. I seen some video's of the NVX's and most tend to be underrated.

How is the sound quality on the NVX's for high's and mid's?

As far as speakers go; Their "entry-level" stuff is nothing to get excited about. The next step up worth considering for most "upgrades". Their "Top of the line" "X-Series" is really impressive stuff, and its only one's I'd consider, but Expensive. Unfortunately they don't make a 6x8 X-Series , and although I obviously have no problem going with 6.5" for the fronts, there's very little to match them for the rears. AND Expensive.

Their full range amp is pretty awesome. I'm not going with it Just for the sake of uniformity, I am honestly impressed by its performance.

I only ask cause in the past I've had some amps that were muddy sounding and some that were very clear sounding.

Based on my experiences with the Full range stuff, it's top notch. Granted, I didn't hear it in a 2006 Ford Focus. Variables are everything. Needless to say, I'll give my review on the JAD800.4 - along with speakers i go with - once its in.

Speaking of which, if anyone wants to see a picture of a specific part of the install, feel free to ask. Ive got plenty, just didnt wana turn the thread into Instagram.

If you insist.

Here's the Plate I referred to. The NVX power wire comes pre-loomed & pre-wrapped.



Obviously ran the Power Wire along side factory wiring. I used Many Many zip ties, very freely.



The main Ground is underneath the Rear Passenger Side Seat. It is the bottom belt mount peg/bolt.



Paint is scrapped away down to bare metal. The peg is used as such, so there was no nut to screw down.



I removed the Spare Tire, due to the added weight. I'm riding on 1yr old Falken's, so I have no concern of needing it anytime soon. As most Focus owners know; The stupid spare is used as a Platform for the Trunk's Carpet/Floor. When you remove the spare, it allows the carpet/floor to fall in the middle. To fix that, I measured & cut up two 1/8" MDF Boards, to create my New floor. I kinda wish I would have used Birch, but meh.



The added benefit of doing this, is that I am now able to properly Hide my wiring. Especially since I've ran my 4 Channel RCAs ahead of time. Also, to keep the woofer from sliding everywhere, I was able to drill into the wood to mount a bracket, as opposed to drilling INTO the damn car.



I used Banana Plugs as "Quick Disconnects". Just in case I ever need my trunk space back, I can easily remove the sub. The double speaker wiring is due to my dumb self forgetting to get 12Gauge speaker wiring. So instead I doubled up on the 16 Gauge that came with the Amp Kit.



Here's a close up shot of the Pepsi-Sponsored Amp Spacer, the Stinger Gauge Adapters (0 to 4 Gauge), and the doubled up NVX 16 Gauge Speaker wiring.



And Yes, the Spacers DO actually keep the amp off the carpet.



Lastly, the mount location of the Bass Level Knob. I lost the Left screw .



Again, Let me know if there are any specific pictures you guys want to see.
