Jl Audio 300/4 Car Amp

This is one of the best modern 4-ch amps! It is extremely well built and produces very clean sound. Definitely recommend!

This is truely a quality amp very well designed & thought out. The designers really had us system enthusiests in mind when they made this JL 300/4 amp.

Every adjustment to fine tune our mids tweets, fronts & rears. The quality shows through in the amps case, design, switches, filters, combinations of options & all the way to the allen head wire snug downs is nothing but quality.

I use 1 of my JL 300/4 to power my Rockford fosgate T162S 6-1/2 mids & tweets front & rear. The clear tones are so life like its difficult to believe that much clarity can be heard while being pushed to its limits. The JL amps are bullet proof.
This amp is worth every penny paid & more!

The best amps for your money (true watts rating on the amp). Work great and stay cool not like cheap amps getting hot then shouting down. All that I buy when I do a sound system, because I know what I am buying is the best out there at this time. You get what you pay for. I know there not cheap but they will out do higher rating amps out there.

Thanks Jason

These amps are the bomb, especially since they are made by JL AUDIO. All of the JL AUDIO items are bad ass. I have the JL AUDIO 300/4 in my car that is powering up 2 6x9s and some components in the front and they sound awesome. These amps are so cool that you can make all the mids and highs very clean cut and crisp. I recommend this amp to anyone interested in getting one of these.

Ok so as a fully licensed and certified installer who has works with everything from this weeks chain store special to so pretty highend equipment i have to say If i ever had to pick just one brand it would be JL Audio. This amp is simply stunning. the RIPS system makes your music as full as it is suppose to be no matter what the voltage is and the sound quality is simply amazing. To keep this review rather short because i could ramble on for days about my opinions of JL Audio equipment. If you are ever trying to decide on what product to put in your car and JL is on your list... Go with JL Audio and you will not be disappointed.

The JL amps are the standard for car audio. There are amps that would be considered better, but at a much higher cost.
When connected correctly, these are just bullet proof. The manuals for these are are are clear on the operation and set-up, and can be found at the JL website.
For the average audio enthusiast these are the best power and features for the money.
My setup-all bought from ebay! (Alpine HU, Focal Polyglass 6" components, JL 300/4, JL 10"subs, JL 500/1)

Works as promised , no issues no hassle. Decent price compared to others on ebay.. thanks .....................................

Pro(s):
1) Very clean sounding
2) Crossover is great, with high pass (HP) and low pass (LP) that you can set up to 5,000 Hz which makes an active mid-bass and tweeter setup possible. The crossover is very flexible and one of the main reasons for going with this amp.
3) The amp is built like a tank, lots of heavy aluminum and nice speaker and power connections, no annoying covers to remove, everything is well thought out. 4) The black heatsink looks cool and that should count for something.
Con(s):
1) The amp gets a bit warm if not well ventilated.

It has be the best amp for the money hands down. Very flexible amp for sound quality and reliability. I have 6 of the these and they never had any issues.

i like the jl audio amps are exellent devices hi fi
and top end quality, an this seller have one and i pay just ammount

amp is awsome works great and condition was as stated. Amp was as clean as a new unit and functions the same. great deal great seller

It's is a good all round amp. Going to repair the amp and not shore if I'm selling it or keeping it. Thanks for the deal.

I have never been dissapointed in a JL product, may i tell you the slash series amps like this one are great. Because no matter if you have a crappy stock battery and old wiring or the best of the best. Your getting the rms power rating you paid for at any voltage from 11v-14.5v and from 1-4ohm which I have never seen any other amp capable of doing. Buy JL products and you know you've got what exactly what you paid for.
