JL Audio Slash 300/4v3

Verified employee purchase (What's this?)

I used this amp to power 2 sets of JL component speakers. It sounds great.

Pros: Clean solid power

Cons: A hair big for under a seat, but worth it once you work it out.

Verified employee purchase (What's this?)

Easy to adjust. Not that big. A little heavy. Has that sound I was looking for that class d amps can't match. Just wish it had more power, like 150 x4 and wasn't as expensive.

Pros: Sound. Ease of adjustment

Cons: Price. Power.

Tacoma Double Cab Ear Massage!

John from Fort Worth, TX on 3/8/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

I did as much research as I could before selecting this Class AB amp for my Tacoma. If there is anything at all that could have made me happier with the new sound in my truck, I have no clue what that would be! I matched this up with Kicker components in the front, Kicker coaxials in the rear, Kicker Hideaway powered sub, Audio Control LC7i processor, and keeping the factory premium head unit. It sound like a dream!!!

This amp puts out plenty of clean power and makes my Focal components sound their best. I particularly liked how easy it was to adjust the gain using a voltmeter since it took the guesswork out of the process.

Pros: Ease of setup, looks, sound & power!

Cons:

Jl audio makes great amps. My first one lasted 15 years. I hope this one will be just as good. I had a few questions about this amp and Crutchfield's customer service was great, they answered every question I had. Definitely recommend jl audio products and Crutchfield is the place to buy them.

Pros: Quality product, great prices,

Cons: None

Very clean sound at higher volume

I replaced an old Kenwood 4-channel amo with this one. WOW, the difference is amazing. The sound is so clean, I'm very happy I spent a little more money for the quality of this amp.

Pros: Clean, multiple configuration choices.

Cons: Can't think of any.

This amp is everything I hoped it would be. I push it hard and it barely gets warm to the touch. The sound is crystal clear.

Pros: Great sound.

I've been a fan of JL for quite some time. This was an upgrade from my V1 300/4. I have been no less than blown away with how clean and powerful these amps are.

Pros: Clean, quality workmanship, very versatile.

Cons: N/A

Excellent amp

Michael from PA on 5/29/2014

Verified employee purchase (What's this?)

This amp has unbelievable sound. I hear details in music my previous Eclipse amp simply did not reproduce. No distortion at all and truly reference grade sound. However, this amp seems to have unusually powerful midbass, I had to tweak down my PEQ settings accordingly and I highly recommend using dynamat liberally.

Pros: Great sound, no audible distortion

Cons: Expensive

Another awesome product from JL Audio!!!!

Mike from South Jersey on 3/13/2014

Verified customer (What's this?)
Verified employee purchase (What's this?)

I picked this amp up to upgrade my older JL Audio Slash 300/4 v1. I've been using JL Audio products in my Vehicle for about 10 years now. I'm using this amp to push a pair of Focal Integration speakers (temporary until I get the funds to get a pair of Focal K2's) and temporarily pushing a JL 10W7v2 with channels 3 and 4 bridged. This amp not only puts out amazing clear full range sound to the component speakers, but It is easily pushing that 10W7v2 without distortion or compromise despite the fact that it's only sending 150W to the sub!! Obviously this is temporary until I pick up the new 600/1v3 Slash which is gonna replace my 500/1v1 Slash which just gave out on me after 10 years! This amp is a beast and looks awsome with the powder black case. I couldn't be happier with this amp and I highly recommend this amp and any other JL product. You can't go wrong!!!

Pros: Awesome sound and top notch Circuitry JL amps output at least what they are rated at unlike most other brands Good price for what you get, Definitely worth every penny and more!!!

Cons: None

JL Amp rocks!

Great amp. Worth the price. You always get what you pay for with JL Audio. Building a competition system. This amp drives 4 Alpine door speakers in a 2010 Highlander. Mounted underneath front passenger seat.

Pros: Rocks. No issues thus far.

Cons: None at this time.
