You are right about the scratching sound meaning the speaker is blown. The other one by it not playing it could mean the voice coils in it are blown or burnt.The safest way to check the speaker is to connect it to a standard 9 volt battery and listen for a popping noise when you make the connection and look the see if the cone stands up as long as the connection is made n returns to normal and no noises when disconnected from the 9 volt battery. To test this while the sub is plugged in to the amp but out of the box move the cone as far in and as far out as it will go. If it comes on while u hold it on either one of these positions but when released it goes back to not playing then the coils in it are blown or burnt and is no longer any good. As for selling the box its on you, aim anywhere from 2/3 to 1/2 the price you paid for it minus the speakers.

If the lights on your sub box aren't coming on it's either your ground of power wire came loose or the transformer blew. As for the subs, make sure all the connections are good, especially on your RCA wires. If your amp is getting power, then check your speaker connections. Also, make sure to turn the gain know up. The gain knob is located next to the RCA input on the amp. Let me know if this helps.

500w for the whole sub. Not per coil.

Do yourself a favor do not get anything Pyramid they are cheap for a reason and you will not get good bass response from them even in a optimal enclosure.If you want nice bass for little money go with lanzar opti 1535D sub you can pick one up for around $265 and will blow away Pyramid any day.

i actually have 2 12" type s's and i did the same thing just wanted a cheap amp... i went on ebay and bought a pyramid 1600 super blue series amp..... its 1600 watts and ive also hooked it up to type r's and it POUNDS!!! ill copy and paste the website where i got mine from on ebay... if you tune it right it'll make it so you cant breathe inside your car......http://cgi.ebay.com/NEW-1600-WATT-PYRAMID-PB559X-Car-Audio-Amp-Amplifier_W0QQitemZ350169009069QQcmdZViewItemQQptZCar_Amplifiers?hash=item5187b30bad

well if u bulid a box u need to leave air holes in it b/c if u dont they will blow

I would say any decent pair of 12" or 15" (single 4 ohm voice coil) subs that can handle at least 500W rms would work. The rest is going to be based on cost, type of box, type of music, etc.
