Great for powering speakers

I own this amp, and there are a couple of things that are great about it and somethings that totally suck!
First off, This amp is great for powering components. makes 150w@4ohms perfect for most 5/1/4 comps. good for powering multiple speakers at 2ohms as long as their total RMS is equal to 230watts. It says 800 max and I doubt very much is would get half that high before blowing. You can bridge it for one sub@460watts at 4 ohms only, do not run bridged a 2 ohms or else severe heat, blown fuses and funky smell will result and of course damage to the amp. The amps features are so-so and so is its performance. This amp is not a very good choice for subwoofers. Like I said earlier its a great value for people looking to power some speakers or a sub!

Bang for the buck

If your looking for a decent amp thats not going to make you broke this is your amp. I had this amp 4 a year with with many subs hooked up to it and it could pound all of them. it blew the crap out of two stage one rockford subs after a month. I had the amp and was happy with it until I decided to upgrade to JL. I had the amp hooked up to two JL w3 for about 3 month and I powered them and they were pretty loud too. But the amp was turned up all of the way and it eventualy fried but its was onyl because I had it hooked up to two subs the demnded about 4 times the amout of wattage it could put out. Great product and best bang for your buck when it comes to amps

Good Amp

If your looking for really dependable amp here it is great power wont shut down has a built in fan and the best thing it's not that expensive like others, not to mention it's a kenwood, I have this one in my wifes car hooked up to 2 10'' audiobahns briged and they hit really nice, she dosent want to much bass so the bass boost controler included helps.

are u guys kidding me

***Edited for content / vulgarity***
are you guys joking on what u rate these amps at. i got the older style, which is diff, but it cant be that much different, and its so f---n' loud. i have it hooked to 2 crossfire BMFs with stinger 4 gauge wire and a 20 farad capacitor. it gets close to beating a blazer with 1/0 power cable, stinger cap,kx1200 amp and 2 L7s. i give this amp a good rating. although i am going to sell my amp and im gonna buy the kenwood7252. i need a lil more watts.

ok amp

this amp is far as looks and durability...power output is overrated though...had on 2 memphis subs and it barely moved them...for the money its ok but....spendin this money u'd be better off with boss riot or powerdrive series amps...this amp is ok but i would not purchase another one unless price dropped below that of the new boss amps
