Well actually it's fairly important that we know which Type Rs these are and how they are wired up inside the box.  They make the Type R in a 2-ohm voice coil DVC and a 4-ohm voice coil DVC, and what kind of amp you get depends heavily on what kind of speaker/sub load it will have on it.

If you have the 2-ohm DVCs these are your wiring options;  and if you have the 4-ohm DVCs then these are your wiring options.

With the 4-ohm DVCs you can use just about any 2-channel amp out there and bridge the amp to a single 4-ohm load to push both subs.  With the 2-ohm DVCs youwill need an amp that can handle a single 2-ohm, which will almost certainly only be a subwoofer amp cuz hardly any 2-channel amps can be bridged to a 2-ohm load.

Think about the JBL BP600.1--it will handle both the 2-ohm subs and the 4-ohm subs and will send 300 watts RMS to each sub.  Only probably is it might be hard to find as it's a discontinued model I think.

You'll need to know the stats, cause Type R's come in 2 Ohm and 4 Ohm Impedence. Take a look at the bottom of the speaker, it should say what it is or ask ur friend what it is.. If not, then take it to an installer somewhere and have them rig it up and test it.

Both speakers have the same general stats;

  • power range 100-300 watts RMS (150 watts RMS per coil)
  • peak power handling 1,000 watts
  • But the Amp you need all depends on your impedence, and how you wire them together.
    Check this if you're not sure how to wire them

    For amps, looking at your Sub Specs, the Boss Audio"Chaos" Avarev800 for the 4 Ohm or the POWER ACOUSTIK "Gothic" OV2-1200 for the 2 Ohms should be good. The Boss Chaos is a 4 channel Amp, that can be bridged(one speaker to 2 channels) to (1200Watts Max)300Watt RMS x 2 at 4 Ohms. The Gothic is a 2 channel Amp rated (1200Watts Max)300Watts RMS x 2 at 2 Ohms. Look for them on Ebay, or this place ( https://www.justamps.com/ )and you can get them pretty cheap.

    At JustAmps, the Chaos is $165 and the Gothic is $155 (w/o Shipping)

    Good luck with you subs.

    I would stay away from the amps listed above. I would suggest you look at more reputable manufactures. As soon as you post how many ohms they are I will give you some suggestions.

    Why, whats wrong with them??

    Mine works fine and I didn't pay $600+ for it.
