    Didnt look at the pics,but rms watts is the continous power of the amp.Where peak wattage is the max wattage you will get for a short amount of time.IMHO rms is more important

    hey man!!
    don't pay attention to the peak wattage.what you need to look at is the rms wattage of the amp.thats what kinda power you can get out of it while you are jamming.the peak power is roughly what the amp can produce at a brief musical blast,granted you have the electrical system to supply enough power.and to answer your last question,no you or not utilizing your sub and amp to its full potential.you could with the amp bridged at 2ohms,but the amp won't stay on long because it will overheat and go into protect.
    that alpine sub is a dual 4ohm version.you won't be able to wire it correctly to get the 500 watts rms the amp puts out bridged,or supply the sub with the 500watts rms it calls for.only way to make the combo work,is gonna be for you to find a dual 2ohm version of the sub,or get an amp that is stable into 2ohms when bridged.

    My Setup

    Dont look at peak, peak is basically nothing. Its all about RMS wattage.

    +1 for peak wattage is a worthless spec, ignore it

    All amps will overheat over a period of time no matter how you run them. If you are truely worried about it then buy a fan for it. I have the MTX1501D amp wired to 2 infinity reference subs. I can't turn the amp up any higher than about 50% cuz the amp is to much power for the subs. I use to compete at comps a few years back. I had a 96 firebird with 6 infinity subs and 2 of those mtx1501D amps. 149db's!!! But my days of rediculous bass are over. I recommend you just wire that amp up with that sub. Good choice also, the Type R's are good subs. Anyways if you notice that amp is getting hot to quick and constantly shutting off just try adjusting the gain and crossover a little bit untill you get a good clean sound out of your sub and you aren't drawing as much power. Also your setup is only as good as its weekest link. Make sure you buy the proper wiring kit (power,ground,rca's etc...) for your amp. If you notice your lights are blinking when the subs hit you may want to consider a nice Capacitor also or turning that amp down a lil bit more. Have fun man!

    it looks like that sub is too small for the amp..thats if you bridge it at 2 ohms. p.s. that w7 looks banging..is that 13.5''? and you running both 1000/1 to the w7?
