Impressed...

I bought this to run the new kicker LED speakers, 4 of them in our boat. it's not a marine amp but I installed it off the floor on some bushings and under our helm. I was amazed that an amp that cheap could sound that good. I was very skeptical! Plenty of power and it just so happened to light up with matching blue LED in my boat! Never felt warm to the touch during use.

Pro's: excellent price, provides plenty of power to run 4- 6.5" speakers.
Looks awesome lit up. I even got a price match!

Con's: little bigger than I thought

Amazing sound!

I have this amp running two infinity kappa 2ohm 6.5s in the front and 2 5.25 Rockford 4ohm speakers in the back, and they get loud! I am very pleased with this set up!

Great power supply!

People trash talk hifonics saying they're not as they used to be but i beg to differ.Every company except one or two make their products overseas and this is to make the product more affordable for us, unfortunately quality can suffer, but thankfully this amp doesn't fall into this category.
I have three amps currently in my car, one sub, 12 other speakers including tweeters. The zrx 600.4 replaced the 6/7 year old jbl gt75.4 i had because i wanted something smaller, more efficient with a new school, power efficient power supply for a reasonable price. Compared this amp to my rockford fosgate amps and i think those would win basically because the new rf amps are the best products they've made in a long long time. The sound quality is good, not great, but i know my speakers have way more clean power going to them now since they sound totally different.Mmids are louder, highsare cleaner and the amps mounted in my spare tire well, held down with velcro but ive read thats a good cool place to mount an amp. No problem except slight whining noise either from an old rca, the gain being too high or maybe crossed wires, im fairly certain it's not the amp tho unless gains just up too high. I use my zrx600 to power 6.5" infinity kappa coaxial 100w rms, 6.5" jbl p665 components also handlea nominal 100w (whch btw they bump some amazing mids now, infinitys do too).
I recommend this amp to hifonics loyalists in need of an efficient 4ch amp to power some mid/high end speakers that can handle atleast 80-85 watts,but i bet it could power a couple of 10" kicker comps easily. Ty sonic! As always best deal online, free shipping and good service is a bonus!

Great amp for mids and highs

This is the amp to buy for mids and highs. I have it on four 5x7's and it rocks them way better than I thought it would. The price of this amp is very low for what you get. I have had way more expensive amps that haven't preformed as well as this one. Great buy for sure.

Great product if it works

This will have been the second one I have purchased. I purchase one about a year and a half ago it worked great for about three months and the one channel started intermittantly going out it took about another three months to trouble shoot the problem. When finally everything pointed to the amplifier I replaced it with the same one to prevent changing connections so far prolem solved and working great as I said great product when it works
