Fiat 500 Abarth (Hertz, Helix, alpine)

[bigaudiofanatic]

Today the build started for a customer and his Fiat Abarth. He contacted me talking about hearing the factory system in the BMW M6 and wanted something just as good if not better. Having a limited budget I tried my best to meet that goal. He wanted to limt the space taken as he uses the car daily. We talked over products for a good week, finally with the list in hand I was given the keys and cued the music. :D

How does she like the 10 in that size car? I will start glassing in the next few days, I have to build the false floor first.



Thanks :D

Today I got a late start simply because I was waiting for the set of focal's to get in.

Focal's

After drilling out the rivet holding the stock speaker in place and installing a small amount of dampening material I installed the speakers with no problem.

Believe it or not there is a small amount of space still there.

Been a busy few days. I didn't get a chance to work on the car yesterday however today I did get a few big items started. The head unit as well as the wiring harness came in. I am still waiting on the hertz speakers for the front! That is what's holding the front being completed. Tomorrow I will go ahead and make the spacers for the doors as well as install the laser jammer.

Wiring harness made.

Today I built the spacer rings. They will be bolted into the factory location. Luckily the windows don't even come into the area the speakers are located.

http://i483.photobucket.com/albums/rr199/bigaudiofanatic/IMG_1166.jpg

First I made the correct opening with my circle jig. Than placed the factory speaker in the hole and traced out the outside.

Another layer of fiberglass was done on the sub box. Tomorrow laser jammer.

Today the laser jammer was installed. Luckily I didn't have to fully remove the bumper just worked behind it. I used the included mounting brackets and installed them into the slit towards the middle of the fiat's bumper.

Installed the spacer rings after a coat of paint. They were mounted to the factory holes using bolts and locking nuts.

Great Work man

[Kingstroker]

Nice job, can't wait to see more. Was it just me or did anyone else notice the battery was almost as big as the motor.

[bigaudiofanatic]

Everything is starting to wind down. The speakers come in tomorrow and most of the car is already put back together.

Installed the double din dash kit. Sadly you have to cut your vents but a double din looks fantastic in this location.

[towtongebug]

hi,

I do not think that you can fiat 131 abarth rally in malaysia. It is
always and still high on my birthday list. You may have found few of fiat
131 abarth replica from 131r here. It is still possible to see fiat 130tc
ritmostradaabarth, which I had owned once last time. Please let me know
should by luck you have found the original worked-prepared 131 abarth.

[pickup1]

How is the dsp to tune?

[buset46]

neat build, definitely tuned in!:popcorn:

I'm looking to do an enclosure exactly like that in the near future...definitely tuned in. Looking awesome so far.

[bigaudiofanatic]

Sorry for the delay with updates. The owner had some things come up where the car has to go back to him. Today I finished up the install. Everything went under the false floor instead of having the processor behind the factory bose cover.

Came out very clean customer was very happy.

Thank you, I am not a big fan of crimp connectors, this way I get a clean connection that is also protected.

What do you mean, as far as size needed? Or tuning after installed?

Meant to write volume, not tuning. LOL

Ah you do measurements if it was a normal shape however with this kind, before fiberglassing after wrapping to give it the shape, using foam peanuts you can dump them into the box to give you the volume size, than measure them in a normal box later.
