Hello diana_soto55,

The MRD-M301 is a discontinued model but originally sold for around $250-300. A more powerful current model is the MRP-M500 that sells for around $200 and under at discounted online stores.

Hope this helps.

Correct settings

I am not familiar with your amp, but any amplifier performs best when the output stage effective resistance exactly matches the load resistance. So, read your 15" subs and find out number of ohms, then set the amp to that number. according to your amp's specs: if you have 2 ohm speakers, you can draw 350 watts from your amp. so purchase 2 ohm speakers
