Powerful Amp for the size

I bought this amp to drive my JBL 6x9 on the rear shelf. The Amp is really powerful and although the nominal power of the speakers are about 20watts RMS more than the amp,The amp drives them with ease and actually I cannot push it nowhere near its capability, The whole interior of my car rattles to a point that I feel like my rear deck cover and roof liner would pop off. Anyways I didn't buy my setup for loud music, I just wanted crystal clear sound stage out of it and I got it! :)

The only problem that I had which I'm not sure why it happened and it might be a coincidence was that my battery died(being more than 3 yrs old) and went bad after about 10 days after I installed the amp. After I changed the battery I don't have any problems with my battery, but I should mention that after changing my battery, I manually turn off my head-unit before turning off the ignition in my car. It could be also my head unit's fault to leak out power while ignition is off, I haven't got to figure it out yet.

Love this little amp

I purchased this amp to run my rear Alpine SPR-60 speakers and I couldn't wish for better sound or power from an amp this size and this cheap. I have the gain turned up a quarter of the way up and it plays my Alpines LOUD and CLEAR and matches my NVX 800.4 for my front component perfectly. I can turn my Kenwood Excelon receiver up to mid 30's and there is no distortion at all. I'm assuming this amp is underrated by a decent amount given the sound quality it displays. It's a great size which is one reason I purchased it. It fits under my seat next to my NVX amp very well. If you need a small amp to run door speakers then buy this one. Also, if it goes into protection mode often it could be because your positive and neg speaker wires are touching. Even one strand of wire will cause the amp to go into protection which is a good thing if you ask me. Love the JBL.

Great amp for my pickup

I needed a new head unit and I decided at the time to buy a power amp (for the first time) and new speakers. I got the GX-A602 from Sonic, and I bought another one to use in our RV. I also got my JBL speakers (one set, the 4x6 GTO model) and a set of GX602s from another vendor. I hope to grab up the GTO 629s for another installation.

The amp was my first installation and the most difficult thing I encountered was what to do with the remote turn-on wire, and what to connect it to. I will never understand the tech writer's penchant for using 200 words when 50 or fewer (in this case, MANY fewer) will do. How about, "connect the remote control wire to the blue/white wire coming off the back of the head unit."?

All complaining aside, this is a KILLER little amp. I can turn the head unit to as loud as I can stand it and the sound is crystal clear. John Entwistle from L@L never sounded so good. Big band jazz sounds great, blues, country, rock and roll, classical (Stravinsky's "Firebird Suite") sound amazing. Like I was in the middle of the orchestra pit.

The installation of the amp was a bit of a struggle because I'd never done it before and some of it was daunting. I'd never done the power wire off the battery, never mounted anything like that, it was all first experience installing an amp. I ran my speakers in parallel, but instead of going to one speaker and then heading on to the next, I used a pair of wires for each speaker, wired in parallel coming straight off the speaker terminals.
But oh man, that JBL sound...nothing better. NOTHING. Buy this amp. You won't be sorry.

Powerful

Very strong amp more than enough power, clean and clear sound, buy it you won't be disappointed.

Great value

very good amp and cant go wrong with jbl on anything

JBL GX-A602

I recently purchased a set of JBL 6.5” component speakers for my Honda CRV. I just had them running off my Pioneer head unit and I thought they sounded really good...until I installed this little amp! It’s incredible the difference it made in clarity and distortion free, loud volume. It’s a great little amp to run a set of components and a perfect match for my JBL GTO629s. It’s also a nice looking unit and the small size makes it easy to mount anywhere. In my opinion this is a great choice if you are looking to add some power to your component or coaxial speakers and not break the bank. I did quite a bit of research on amps and you just can’t do any better than this for under $60!

JBL GX-A602

I purchased this amplifier to power a single 10 inch JBL sub that is in a ported tube. I used this setup to replace a defective factory sub in my BMW. It’s compact size mounded nicely I my trunk and has plenty of power to drive my single 10 with no problem. I’m Running it bridged at 4 ohms and it does not run hot nor have I had any issues. This amp is a great bang for the buck.

JBL GX-A602

Loud and cheap

Simple to hook up, works great, loud and proud to own. Driving my infinity 6x9s at full range.

Good value

Sounds good. I have it wired two ohms and seems to work well. Not enough power but well worth it for the price. Good value.
