4smartcar under dash sub - anyone???

[Smart990]

Has anyone here purchased and installed the 4smartcar.com under dash box and sub? If so tell us how it sounds and what amp and head unit your using.

I purchased one, there is a delay in shipment due to an enhancement/modification needed. I will let you know when I get it. I prepaid it 2 weeks ago.

It looks like a good deal, let us know when yours arrives. I already have an amp and I am ready to go.

Just received it, very nice enclosure, very heavy. The connectors are very high quality and the internals are wired with Monster cables to the JL Audio subwoofer. It's supported at 2 points, the bracket attaches to an existing nut on the firewall and the otherside attaches to an existing bracket at the front right corner (pretty obvious). I will install it this weekend and let you know.

Please excuse my somewhat dumb question. Can this under dash sub be connected to a factory system as to complement it. If so what would be needed as far as an amp and how would it be wired or connected into the factory system/radio. I am assuming it would need to be adjustable in some why.?! Any help or support in this effort will be greatly appreciated.

1st Attempt, the box is a very tight and does not allow the firewall bracket to attach and the pressed on pronged T-Nut came loose (flimsy) from the other side (which attaches to the dash frame).

2nd attempt, this is like figuring what comes first the chicken or the egg. I had to remove the subwoofer from the enclosure. Then remove the pressed on T-Nut. I replaced the T-Nut with a 6mm (10mm head) bolt about 1 1/2" long, pushed it through the existing hole and tightened a nut on the other side with a washer (see picture). This made it much more solid and stronger. I then trimmed the existing bracket 1/2" and drilled 2 new holes. I positioned the enclosure and tightened another nut and washer to the dash frame. Then trim some of the plastic from the right side of where the bracket bolts up to (see picture), then install the firewall bracket with the existing nut. Holding firmly up on the enclosure, I screwed in 2 new self tapping wood screws. All that was left was to run the wires to the amp and DONE ! I have the Diamond D3 500-4channel Amp with 400 watts, I used 100 watts each of the front Pioneer Premier Speakers and bridged 200 watts for the Subwoofer. The enclosure and JLAudio 8W3v3-4 subwoofer (8 lbs) make a huge difference in the sound, this car really KICKS, especially when I play my Taiko Drum CD I bought from Japantown in San Francisco!

Would it be possible to get the dimensions of this box from anyone?

[tigerwong58]

Sorry, I'm against giving out information like that. Since someone else designed and made all that effort for the enclosure.

tigerwong58, car is looking great. do you have sub-enclsoure installation pictures? thanks in advance.

I was more concerned with the volume of the box than recreating it. Nowhere on the 4smartcar site does it say it. The sub I have needs .35 cubic feet and that box looks too big. Just looking for conformation.
