Awesome Sub

Crutchfield customer from Atlanta, GA on 10/13/2019

2008 Smart fortwo

The installation went just as the directions suggested. It requires the removal of the sub from the box but I'm perplexed why. Other than reduce weight during the install, I'm not sure why this step was necessary. Plus reinstalling the screws are difficult especially at the footwell arch. Otherwise, the unit is amazing in quality and sound. I highly recommend this company and product.

Pros: Quality Good instructions

Cons: Removal of the sub speaker

Great improvement for Smart car.

Very well constructed, sounds great! It takes some time to get it in, but I ended up modifying the heater duct and removing and reinstalling diverter motor for a much easier install. These two steps made it MUCh easier. Also dont take the sub out of the box, too hard to reinstall after the box is mounted. Thats the reason I cut the duct and fiddled with the motor. Only put 3 screws back on diverter motor but it does not create an issue.

Pros: Quality all the way, hidden, great improvement to sound.

Cons: Should have the simple mod of the duct cut and diverter motor removal instead of removing sub.

AMAZING!!!

Incredible! The install is super easy up until actually fitting the sub in the space. My recommendation, take the speaker out of the box and reinstall the speaker after everything is mounted. Incredible sound, I had a 12" sub in the back of my Smart, and am now selling it, cause this 8" hits cleaner, more efficiently and I am in LOVE with it! You can hear it everywhere, top down or not. I have a 2008 Cabrio ForTwo

Pros: Incredible sound, invisible to the outside world.

Cons: Putting the sub in place is a little tough, but not impossible.

big bass in small car

There's a comparable underdash setup for The Smart's at half the price- with a 1/4 of the bass performance- still an improvement even over the Smart's that have the underseat sub (as mine did), but neither compares to this JL Smart car sub. I truly believe JL Audio did their homework to give you no holds barred clean and powerfull bass is a stealth setup. I've been a loyal fan of their subs for years, so I had high expectations of this setup- and it delivers. Nice punchy bass with well defined notes in a sealed enclosure- not the crappy bandpass peaky sound. Wanting to keep the whole thing stealth, I also purchased the XD400/4 channel JL Audio amp and bridged two of the channels to run the Stealthbox. Amp fits under the seat with room. It's insane! - For those that are looking for the ultimate setup for a Smart- this it it- and it's stealth to boot. For those that want it- the Smart Car becomes a giant boom box. My vehicle is the Smart Cabrio- a droptop is the worst car to get a stereo to work nice in, however this one has gorgeous clean sound in even with the top down (much in part to Smart's well thought out component speaker placement). I'm still using the Smart's OEM premium sound front stage speakers on the remaining two channels- when those go, I'll be looking at a JL component set.

Pros: For those who know JL Audio, it's everything you would expect from JL Audio. Stealth setup. Very high quality fit and finish, high quality components- lots of pride in manufacturing detail.

Cons: Cheaper stealth setups exist- and come with cheaper performance.
