Christopher A. Johns
I have been pleased to include this amp with my stereo system and would recommend this amp to anyone looking for entry level to mid-level equipment.

This amp stays cool, gets only warm to the touch even when cranked to the max.

This amp when bench tested at a 2 ohm configuration puts out about 600 real watts. If you know anything about car stereos, this REAL wattage is the only thing that matters, not what the amp manufacturers claim wattage to be. This amp doesnt get hot, and is a serious performer for the money. Class D means it is extremely efficient, and its a mono subwoofer amplifier. For those of you with small 4 cylinder engines and small alternators, yes your headlights will dim no matter what amp you put in there. Get a capacitor if you have a 4 cylinder motor. I have an S10 with a 4.3L V6, stock alternator rated at 110 Amps, and my headlights do not dim. I dont have a capacitor. This amp slams whatever is connected to it. For the money, you can not beat this amp.

Intro: This review is long, I am sorry for the length. I bought this amp through a different web site. Purchasing this amp was to upgrade my KAC-9102d amp, I wanted to move to an amp that would handle 1ohm impedance. I have been working with stereo systems for 11 years now as a hobby, I build mid-range systems that compete with high end systems. My old system included the KAC-9102d powering four (4) Power Acoustic FUBAR 12w subwoofers wired in 2ohm on a single channel. The amp and subs were 5 years old and ran as good as the day they were purchased.

First Impression: When I got this amp I was a little disappointed, to be honest. This amp doesn't weight very much compared to my old Kenwood. I thought the fan was a cheap add on, the fan was the first thing I replaced in the amp. I modified the intake and output holes adding high flow Sunon Vapo Bearing fans. With some soldering, drilling and modification the positive and ground of the amp now use lock connectors and accept 2-0 gauge wire without any issues. Other than that I didn't think much of the amp, wouldn't know until hooking it up. The modifications took less than 2 hours.

Setup: As stated before, this amp was purchased to replace my KAC-9102d. The bar was set high, so it had a lot to live up too. Setup includes 2008 Honda Civic with sealed trunk and speakers removed from the back deck, Sony Xplod MEX-BT3800U, 2 gauge power wire, Yellow Top Optima, 20 farad capacitor, Clarion equalizer, two Power Acoustic FUBAR 12w subwoofers and the KAC-9104d. The head unit sub db is set to 0. My EQ is turned up 2/3 of full volume, RMS output is around 4.5 volts currently. The amp is receiving 4.5 volt pre-amp input tuned to specific frequency ranges.

I have this amp paired with an Alpine R12 (4 ohm), and it is amazing. With the gain over 3/4, it is TOO POWERFUL for any kind of conversation in my 08 Civic.
I also bought a 1 Farad capacitor, because my headlights were dimming.
This amp has not cut out once, even in near 100 degree heat and bumpin'.
I recommend this amp because of it's flawless performance, light price, active cooling, and heavy hitting power.
I am very impressed with this amp.

Amazing product, bought this amp to use it with two 12" Jack Hammer MTX 500 RMS each one, and the sound is awesome, the only think it doesnt come with is the remote woofer level, but is ok you can live without it. It doesnt overheats or anything good system of cooling with two internal fans, easy to install and to customize the sound... good product...

Got this amp pushing two rockord fosgate P3's and if hooked up right they mate perfectly, been pushing them hard all summer and I haven't had any problems, they were meant for each other, I paid about close to six hundred for the whole hook up, Cap, woofers, amp, but it is a match made in heaven, well wirth the money, you get what you pay for, if you have the money I say go for it

i have this amp on a 10' Solo Baric L7 at 2 Ohms and the amp can provide all the juice that my L7 needs and then some. the amp does not overheat and it also dims my lights with the stereo turned all the way up but thats what happens when you got a strong amp like this one. its great for the price and its performance is also great.

I have this amp connected to two alpine type Rs in a sealed box wired to 1 Ohm and MAN IT MOVES AIR! The amp has not cutout once. I have 45 min commutes and has not caused any problems. It gets alittle warm but does a fine job of cooling its self. Great amp,sounds good and the price is right. I would buy another one again.
