Great Little Amp!

The following review is for VADM1, which is a part of the bundle you are viewing.

I bought this to replace my JL 250/1 because I couldn't run a 1-ohm load on it. This amp doesn't sound as clean so I ended up hooking both up, one on each sub for a 2-ohm load. The sound quality got better and it puts out a great amount of power. It slams a kicker Comp VR 12 at 2 ohms.

Small Amp Tons of power

The following review is for VADM1, which is a part of the bundle you are viewing.

Was really skeptical about how much power this little guy put out but it powers my one kicker perfectly and its so small you can place it anywhere if youre wanting a clean unseen install!

Tiny but powerful

The following review is for VADM1, which is a part of the bundle you are viewing.

This amp is tiny, but packs a punch, similar to the other amps in the VAD line up. The only downside is the 8 gauge power terminals and the push-in style connector for the speaker wire. The speaker wires can pretty easily pop out of the connectors on the back of the amp, and I had to use a 4 gauge to 8 gauge reducer to run adequate power and get the 500 @ 1 ohm promised on the box. Overall it's impressive that such a tiny amp can produce such power and be 1 ohm stable. It's compact design means it can be mounted virtually anywhere or easily concealed depending on what your install calls for.

So far very impressed

The following review is for SMW12D4, which is a part of the bundle you are viewing.

So far very impressed, bought with the Atrend 12tk shallow truck enclosure bundle for Black Friday, at a total of only $120, it’s great so far. Installed it behind the rear seats in my 1995 f350 crew cab, paired with a Skar amp. So budget friendly was the goal. It sounds amazing, very clean and crisp, and hits way harder than I was expecting. Build quality seemed great, especially for the price. So far so good! Give it a shot if you’re in the market for a shallow mount subwoofer! Wont be disappointed.

Little Sub that could

The following review is for SMW12D4, which is a part of the bundle you are viewing.

Needed a sub for my Nissan Hardbody. Very limited on space in a single cab. Mated with Skar 350 mono in a sealed box & it’s like a concert inside. Bass drops & plays any genre with clarity. Would definitely recommend.
