Selectable Smart Impedance Technology

Infinity’s latest Reference subwoofers offer incredible installation flexibility. Their low-profile design allows them to fit perfectly into even the most shallow of enclosure. Polypropylene woofer cones deliver exceptional bass response at frequencies as low as 27Hz. But what makes these subs really stand out is their Harman-proprietary SSITM (Selectable Smart Impedance), which allows the subwoofer to present the amplifier with either a 2 or 4 ohm load at the flip of a switch.

Awesome power for small foot print!

The following review is for VADM2, which is a part of the bundle you are viewing.

I needed to power up the 6 X 9's on my bike's batwing and with limited space, the NVX VADM2 fit the bill. I would absolutely recommend this product! Time will tell with durability.

Beyond Happy

The following review is for VADM2, which is a part of the bundle you are viewing.

I was hesitant to put the VADM2 in my pristine all original 550i (E60). After replacing the factory subs they clearly needed more power, but, BMW being BMW leaves no room for typical after-market accessories. Therefore, space is/was a driving requirement for a 300W amp.

The VADM2 is perfect. Small enough to mount over the Antenna decoder and leave plenty of room for the PnP Technic wringing kit. ABSOLUTELY NO ALTERNATOR WHINE. Now the Logic 7 sounds like a rolling studio. Beyond happy. The VADM2 stays relatively cool and provides more power than my ears can handle.

If you have space limitations, want high quality gear, and are borderline audiophile that wants to maintain OEM look don't hesitate.

Curtis was a huge help in making recommendations and providing options. Top shelf customer service. Thx

Big Power Small Footprint

The following review is for VADM2, which is a part of the bundle you are viewing.

Power is great, especially when it's small. What makes this a slight bit better than the B52, is the standard speaker wire outputs versus the four pin molex style connection. Make it much easier to double up connections and go 2 ohm.

The following review is for VADM2, which is a part of the bundle you are viewing.

This little amp rocks. I accidentally fried my old MVPA4 amp. I had already purchased another amp to replace it (Soundstream 4ch.). This little amp is going on a bicycle with a couple of PRV 6.5" speakers. It is beyond stoopid loud/clean/clear/etc. Gets just a little warm after extended use. Currently have it on a motorcycle powering (2) 6x9's. Super loud/clear/etc. It would be a great motorcycle amp for 2 fairing speakers! VERY happy with this amp. If you are looking for a great, little 2 ch. amp, definitely give this one a try! I've been very happy with the NVX amps I've had (the fried one mentioned above was from 'driver error'!)

Substantial for some, Subpar for one.

The following review is for Reference 1000S, which is a part of the bundle you are viewing.

Pairing this Sub with Infinity Kappa Perfect 500 3-way system, because I heard great reviews on this combo. Unfortunately, my taste for deep low end is a little more than what this subwoofer has to offer. If you are placing this speaker in say a regular cab truck right behind the seat. And say don’t want too much bass in your face, and you would like a little rumble, than this is a great choice. I do like the fact that you can change the ohms with a switch of a button. Unfortunately that switch is located on back of the sub, so you must remove the speaker completely to make that change. Would have been nice if it was somehow located outside the box. All things said, If you want plenty of bass and don’t have much room I would recommend checking out JL Audio’s 10” Shallow mount Sub: 10TW3-D4. Sonic Electronix has great pricing and wonderful staff. Nothing wrong there.

Powerhouse! Honest First Impression Install Review

The following review is for VADM2, which is a part of the bundle you are viewing.

I bought this amp to replace a broken Focal 2.350 2 channel amp installed in the fairing of my Harley Davidson Road King Classic. The amp powers two Focal 6x9s.

The first thing I noticed is the mounting holes on this amp are way too difficult to access for mounting onto a custom flat plate inside my fairing. There is just no way to mount the amp with that sized, tiny lock nuts and bolts. When I say small, I mean small. Then the other problem is limited access on the speaker wire side for inserting any bolt with lock nut because the speaker/power mounting is tight fitting where the holes are. So I drilled out the holes and used regular sized hardware, but even then it was difficult.

The instructions need to mention the speaker connection is removable for inserting the stripped wire with a tiny flat head screwdriver. It took me a little while, but I figured it out on my own. Remember to hold it upside down or use that tiny flat head to push the speaker wire tabs open.

I love that NVX included the RCA with molex adapter. I just plugged that in. Took 3 seconds.

When I finally got the whole thing installed and powered it up, I was absolutely flabbergasted on how crazy loud, crystal clear, and powerful this amp is with two high quality speakers rated at 150w RMS power handling @ 4 ohms. Ridiculous! Probably the best I've heard in a long long time. i even realized my Focal 6x9s are probably not good enough, if I want the bass to pound even better. Treble and Mid-range are spectacular loud and clear as a bell. I maxed out my Aquatic AV to volume level 40 and I could have kept going forever with this amplifier. I couldn't do that with my Focal amp, which cost more than double, is double the size, double less in quality, and isn't marine certified.

Now let's see this amp last on a motorcycle. Most can't and are vibrated into premature shorts on the 12v main power inputs. Time will tell.

Because of the mounting holes/tab situation, I subtract a star. If NVX makes little tabs with bigger holes for mounting and throw in the bolts with lock nuts/washers, this would rate a 10 out of 10.

Great work, NVX!

throttle out

The following review is for VADM2, which is a part of the bundle you are viewing.

Put this on my bike to power my handle bar speakers and it offers plenty of power to still sound good even with the throttle open

Smooth and crisp

The following review is for Reference 1000S, which is a part of the bundle you are viewing.

This is the same as the JBL club 10"shallow mount. I wanted the infinity name on it. You can't go wrong with this sub. It sounds amazing in a .51ci box. If you tight on space just get it. You know you want it.
