i have two 10'" Sony Xplod subs XSL101P5; 4 ohms, 330 RMS, and 1200 watts max each. i want suggestions for an amp that would work for these subs and cost around $100. im looking at a Sony Xplod 4-channel 600W amp; RMS 60Wx4, max power of 110Wx4. i understand that you are supposed to use a mono amp for 2 subs but im wondering if this will work??i know this doesn't matter but i have stock components and an aftermarket Sony Xplod 50Wx4 reciever.

im very new to the whole aftermarket audio stuff so anything will help. also you dont multiply the 60Wx4 RMS do you? also if i get a mono amp should it be 660W RMS cause i have 2 subs or what?

Mono amps are great for subs because they are so efficient.  Class-D amps make upwards of 80% of the power they consume into sound, allowing them to be smaller because they're not going to get as hot as a traditional full-range amp.  Since you have 2 4ohm subs, a mono amp is perfect for you.  you would just hook them both up parallel, and you're good to go.  For $100, you're options are limited.  Maybe a friend has an old amp he's not using.  You don't have to get a 660W RMS amp, that's just the max they can safely handle.

That Sony 4-channel could be all you need for those subs, depending of course on how loud you want it to be.  I'm sure you can bridge it to put out around 180 watts RMS x 2.  That's a good amount of power for an efficient subwoofer.  Plus with a 4-channel amp, you'll have greater flexibility in the future.  Perhaps use it for your other speakers when you have enough saved for a dedicated sub amp. Maybe this one.

Just be careful about under powering the speakers.  Don't turn them up too high if you do because the distortion could damage the sub.

 

And be careful about what you buy.  I had a Sony Xplode amp.  It wasn't worth the money I paid for it.  The Subs are pretty good though (I know a guy who has two).

No, you don't multiple the 60Wx4,

You will need to find the amp specs or post the model, but if it is 60Wx4@4-ohms, it is probably 90Wx4@2-ohms, which means it is probably 180Wx2@4-ohms bridged, which will work and is how J Ro came up with that number.

Hope This Helps!!!
