Best SPL amps.. Stetsom, Soundigital

Best high power amps. MMATS, Sundown, DD, DC, IA, AQ, Nendo.

Im sure I missed something

 
How do you like that little Alpine KTP-445 booster? Personally, I would not recommend anything less than the MRX line of Alpine products...
I got it so my speakers could keep up my sub haha. It was put in at the same time my sub was. The Focals I have are rated to 70wrms, so they could take more and it would definitely add more to the music. But for the time being and with the kind of money I can come across it sounds just fine to me. Plus the only thing my friends ever care about is the bass. haha. But that power pack will be upgraded some time when I can. But for now, it's perfectly fine and I dont feel like I'm missing too much.

lol...well, it is good to see you have a sense of humor. And as long as what you have sounds good to you, then that is ALL that matters.

 
lol...at least, if you didn't like it because it put out too much power or some shit, you could sell it for almost what it cost new. I am just pointing out that it is very hard to say what brand is best...especially by cost.

Care to guess which amp this is? ...would you buy it based on Specs?

Peak Power Handling:

2 ohms: 600 watts x 4 channels

Bridged @ 4 ohm: 1200 watts x 2 channels

RMS Power Handling, 4 ohm: 300 watts x 4 channels

Variable Low-Pass Filter: 35-160 Hz

Fixed High-Pass Filter: 200 Hz

Frequency Response: 9-50,000 Hz

Signal-to-Noise Ratio: > 102 dB

Channel Separation: 90 dB

Damping Factor: 125+

THD (Total Harmonic Distortion): 0.01%

External Fuse Rating: 100A

Dimensions(L x W x H): 23-7/8" x 11-7/8" x 2-3/4"

haha well I have no idea. I havent been around this stuff long enough. But from the dimensions it looks like it's pretty large.

Seeing that it is an amp, and the it says "peak power handling" and " RMS power handling", I would not buy it. Specs alone are misleading anyways.
