To add to my last post.

Keep in mind that Alpine and JL market to the kids that don't really care about sound quality as much as just get loud and bragging rights. Class D amplifiers, because of their circuitry design, are able to be built in a small form factor. The sound quality isn't as good, but, that's OK because it's powerful and it's small - two things that sell to kids who just want to brag about how much power they have in their system.


The general circuitry of a Class D amplifier is not suitable for the frequency ranges seen by your components, even with a high switching freq. Tweeters are capable of reproducing sound in well over the 25k range that is considered the upper range of human ability to hear. A Class D amplifier might be switched at 30KHz. That doesn't mean it's inaudible to humans - maybe not distinguishable, but not necessarily inaudible. So, a Class D monoblock amp is acceptable because we're talking a range between 20Hz and (maybe) 500Hz vs a range of 20Hz to 25KHz. 500Hz vs 30KHz is not the same as 25KHz vs 30KHz.



You'll notice that Audison, Sinfoni, Brax, Tru Technology, Sundown, Zed, Genesis, and McIntosh do not offer a Class D multi-channel amplifier.

The Mag is a subtle subwoofer. You won't notice it till it's gone. There's neither a long booooooom nor a BOOM unless the music calls for it. If you want loud, boomy, distortion, go with something else. This subwoofer is for sound quality - pure and simple.

Yeah and every amp you named there is way above what would be in line with what Sliq should buy. The JL and Alpine amps are fine for him or he could go with an amp from ED. His is not trying to build a SQ competition car. He went to Best Buy to get some stereo components installed. I am not saying dont buy good components, but don't go overboard!

And why is that? All the good info? Or because I seem to have to repeat myself time and again?

There have been some really good pieces of information.

I think it is great how a couple of people have been able to address the OP's needs in mulitiple ways. I think he has some choices which is always good when you are plopping down as much as he is looking at for his system.

I also think it is interesting how some people have favorite brands and brands they don't care for. Just like I think Nokia makes the biggest pieces of shit of cell phones and the only thing I would do with one that was given to me is toss it in the trash.

Nokia does make POS cell phones.

I find that most people (esp when it comes to audio) are fans of the equipment they themselves have or have used in the past. Very few are willing to admit that there's better out there than what they have - much less that what they have is not as good as they wanted to believe it was.

you keep forgetting in mind that i basically got half off on my sub, speakers, and amp and 25% off my deck. i bought everything on discount thats the MAIN reason i purchased my system at best buy in the first place because i got a 1400 system for a lil over 700
