    ok now im not so sure if this is really a good question to ask but i got to, which is better to have a single amp powering my whole system or have one for the speakers and one for the sub? and if two is better would it be good to have them both by the same brand or would it matter if they were different brands?

    People buy multiple amps mostly for ease of configuration. This doesn’t make them better or worse than having a single amp but that’s why most people run them.

    As for brands, it makes no difference if you use multiple brands of amps. In truth, as long as everything is optimally configured, you shouldn’t be able to tell the difference between them anyway.

    I use a 4 channel amp. The 1st and 2nd channel run the front components and the 3rd and 4th are bridged to a single sub.

    yeah im just starting to really read and try to do this, im building my system in stages, head and speakers are first then amp and subs are second ... so what is the bridged mean? is that like having both of the channels used for the amp so its like twice the rating or no?

    and to your questioin of having 1 or multiple amps it just depends on what you are running and how many watts your shooting for. the more wattage the louder but also have to spend the extra cash for things that can handle more wattage

    im not a big audio junkie or nothing jus know the basics lol i do know that when you say watts rating on speakers when it says the rating is usally around 200 for a decent set of speakers dont run them at 200 that usally means a peak power of watts lol i can ask my friend here later and get back to you he is the one that is helping me and he knows pretty much anything you wanna know about speakers or anything

    lemme think i could be wrong here but i think if you are running a 400.4 amp usually your rms rating will be around 50 per speaker which is plenty on a speaker on a 4 channel amp i could be wrong so if anyone know just jump in and correct me

    Bridging an amp is as you described. You take two channels and turn it into one. What you get out of that channel depends on the amp though. Theoretically it should quadruple but must amps limit their current in one way or another.

    You could buy a 4 channel amp and run your Clarus compnents of 1 and 2 and then bridge the last to channels for a sub. This would leave the head unit to power the rear. Or you could buy a 4 channel amp for the front and rear speakers and buy a separate subwoofer amp. It would mostly depend on how many subwoofers you buy or how loud you listen to your music.

    The RMS rating of a speaker is what the speaker can handle continuously and still be covered under the manufacturer’s warranty. It has little bearing on how the speaker sounds.

    If you are going to buy 2 amps, I don't think you want to go with the PDX-5. That one is a 5 channel amp which you would need only 1.

    The PDX line is very good. Lots of power in a very small space, and they're not outrageously priced for what they deliver. Check for a used one on ebay to save a few bucks.

    Amazon also has them on sale quite a bit and you can pick them up for the same price as you will see on ebay.

    Why was the PDX5 cast out of the voting pool? The PDX5 is all the amp you'd ever need and it's the size of a text book.
