I am running a pair of Clif Designs 6.5" components up front. A pair of Clif Designs 5x7" in the rear. These get great, clean, and clear power from the JL 300. All the flexibility with the amp makes the crossovers almost unnecessary. I have 2 12w6 running off a JL 1000 and the overall sound is amazing. That is a true head rattling, breath taking 1300 watts.JL is every bit worth the money.

Perfect Power

I have this amp running two sets of JL Audio C5 component speakers. I don't have the amp turned up that high and I can not believe how good this set up sounds. Even with the amp not turned up very high, when I turn up the volume it goes so loud it is almost ridiculous and still sounds perfect and crisp every time. I highly recommend this amp and all JL products.

Amazing sound quality

I just purchased one of these amps from my local audio store along with jl audio xr components. This amp is amazing. I was running all alpine type s with and alpine mrp-220. I put this amp on my alpines before I pulled them to see the sound difference and it was amazing. Cleaned up the bass a lot. This is definitely the sq amp for speakers. I would suggest it for anyone.

The best for it's size

I own this amp and it is the best. It sounds great, never over heated on me and gets very loud. The only down side is the cost.

Precise

As far as interior amps goes, this is one of the better ones out there. This was the first JL Audio amp I purchased, and it is still alive today.

I can attest to the durability from the above statement. The value is you get what you paid for. Mid-range to higher end audio equipment will always cost more than the lower end stuff.

I had this amp power my interior components hifonics zeus 6.5" comps in a jetta. They were clearer hit harder than I had imagined.

Awesome Amp

I recently installed this amp in my car to power a pair of Polk MOMO MMC6500 components. I went from an Alpine V12 with the same power rating to the JL 300/4. The improvement in sound quality was amazing. The music was so much brighter and clearer. The improvement in detail was so great that I could hear sounds that I couldn't with the Alpine. The amp is a bit pricey, but worth every penny. Highly recommended for the true car audio enthuasist.

Amazing

I have been running of the deck for my speakers for a while ever since my old school v12 amp died. And this is just amazing. It blows the v12 out of the water. So clear and defined it's just crazy. Got to love JL and their great products. Never dissapointed.

This Amp Is Friggin Good

I just bought this amp from Sonicelectronix, I can't stress out enough how much of a difference in sound there is now compared to having my speakers straight from the deck. Sound is so much clearer, crisp, and every little detail is heard. It also pounds pretty good and keeps up well to my JL500.1 amp which powers an Alpine type R 12" sub. I am very happy with this purchase and I would recomend this amp to anyone! Worth every penny.
