My friend wants to upgrade his sound system. He wants at least 1000 watts for low end. The amp he is looking at is the MTX 1501d. The subs will be two Alpine Type-R 12's with dual 2 ohm voicecoils. Total load on system will be 2 ohms. I know that these subs are rated for 300w rms, but I have read that you can put around 900w to them just fine. Anyway, do you think that 1000w would be okay for these subs?
