This compact multi-channel powerhouse employs our Single-Cycle Control switching design and R.I.P.S. technology to deliver 150 W x 4 or 300 W x 2. Tight power supply regulation keeps distortion down and maximizes sound quality. When using the HD750/1 or HD1200/1 to drive a subwoofer system, the HD600/4 is the ideal satellite amplifier, delivering huge dynamics with pristine resolution. From a pure sound quality perspective, we invite you to compare the real-world, in-car performance of this amplifier to any other amplifier on the market, of any type, at any price. It can also be deployed on its own as a very capable 3-channel system amplifier with 150 W x 2 to the satellites and 300 W x 1 to a subwoofer system. This amplifier features a brushed aluminum finish with black powder-coated cast alloy heat sinks and bottom panel. A black powder-coated, gasketed cover is also provided to protect the controls.

Rip off
I spent the last 2 years dealing with electrical problems in my car. I just found out that this amp is shorting out all my electronics, after replacing my stereo and alternator since then and several relays and blowing out my halos on my headlights. This place is a rip-off, do not buy from them they will sell you a load of crap and not think twice about.

This amp has issues.. Buyer beware.
This amp has defects that come form the manufacturer. The amp will all of a sudden go into a permanent protection mode (red/green light blinking). In my case I had the amp stored for awhile before installing. Since 30 days had passed the seller could not refund or exchange my purchase. The only way of fixing the amp is to send it directly to JL Audio for repair which has a price of $ 180.00. This seller is not an authorized dealer to JL Audio so you will not have the 2 year warranty that JL Audio provides. Learn form my mistake and either buy only from a JL Audio authorized dealer or buy another brand. A very expensive amp for what you get if there are problems.

Thoroughly satisfied with this amp!
I've ran an HD900/5 in the past and for some reason I feel like this amp is cleaner, warmer, and brighter than what the HD900/5 could produce. I am running JL C5's off of this and it is so loud and clear it actually exceeds my listening levels. Basically I can't handle how loud it gets and it never distorts my C5's. Take your time and tune this properly and it will amaze you!

JL Audio HD 600/4
This was purchased to compliment my 750/1 amp. If you are need of a well rounded system with plenty of ceiling, this amp is great for that application. I had the XD400/4 before and there is NO comparing the two. Get this, get this NOW lol...

Performed great until failure at 4 years old.
Amp worked awesome until 4 years old and failed. red/green fault code for 5min every cold start. hisses and pops until warm, then runs normally.Great amp while it worked, but should last at least 3x as long.
