I need amp help.

[Pureride540]

I need some help with my amp. I just bought two 10' subs with a 1000W peak and 500W rms. I tried runnin my buddies 700W mono channel but its just not cutting it. When I look online i've been lookin for 2 channel amps. I need to know 2 things. First, when I look online at these amps, take this 900W amp by fosgate, it says something like 150W at 2 channel at 2 ohms. What does this mean exactly? Shouldnt it be 450W at 2 channel since its a 900W amp and 1/2 that is 450W? Could someone please help me out, I'm new at this but I want to learn. My second question is what kinda of amp should I use to run my subs? I'd really like some recommendations(cheaper the better but i dont want something thats going to run like crap) Someone please help

When you find an amp, on just about all but the very high end and the very low end, there are 2 power ratings you can find (not just 2ohm vs 4ohm or stereo vs bridged). These are the max and rms power, the max power is just a marketing gimmick used to fool the ignorant into thinking the amp is power powerful than it really is. The rms power is the actual power the amp is rated at, and it's the power you should ALWAYS look at when finding an amp or comparing amps.

Subs are the same way, many of them are rated in "peak" or "max", and rms. The peak or max power is useless just like with amps, the rms rating is what really matters.

So you have 2 10" subs that are rated at 500rms, is this each or for the pair? Any idea what impedence they are (sing 2ohm, single 4ohm, dual 2, dual 4, etc)? It's impossible to pick out a suitable amp without knowing how much power it needs to put out at what impedence.

My 2 subs are 10' Duals and i believe they are 4 ohms a piece, but im not entirely sure. The website says "impedence: 4 ohms" so i dont kno if that means a piece or together, I think it's 4 a piece because if I look at the same thing, just one sub instead of 2, it's impedence is 4 ohms.

What subs are they (some companies overrate their speakers, so you could quite possibly blow them if you actually sent them 500rms)?

If they aren't underrated, then you would want an amp that puts out 1000x1 @ 2ohm. I don't know any off hand that put out that power at that impedence, but I'm sure there are many.

I think he was saying they were DUALS as in the company called "DUAL" could be wrong.

[sr20de4evr]

ohh, you could be right
why do companies have to call themselves confusing names like that?

I don't know if that company overrates their speakers at all, maybe someone else here does.

My speaks are made by the company "DUAL"

I don't know much about Duals, but they look like they will be the next legacy company.
