I'm getting 2 12" sounstream tarantula 1ohm DVC subs. I plan on running them off of the JBL 1200.1/1ohm stable amp. For some reason i can't find any diagrams showing how to wire 1 ohm DVC subs. Could someone please explain to me how to wire these subs to that particular amp. Also a diagram would be useful as well.

Thanks

To get one ohm net load, wire each sub's set of voice coils in series for 2-ohms per speaker, then wire the two speakers in parallel to the amp for one ohm total load. The JBL BP1200.1 is actually rated as 2-ohm stable to meet its listed noise and distortion specs, although a lot of people wire them at 1-ohms and they will handle the load. You sacrafice SQ by doing that.

I've really got my mind set on this amp. Especially for the price. Will it make the subs sound bad or significantly worse than they would be with a regular 1-ohm amp (which i can't seem to find any) ?

No other amp will sound better at 1 ohm than that one (at least, that you would be able to hear). It's the impedance, not the amp, that affects sound quality. Use this impedance for a SPL system. An SQ system would go at 4 ohms, and you would get a lot less power from the amp.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

the only amps with decent rating at 1 ohm would be soundstream, orion, and zapco...very very high end models and thats exactly why most amps in the $900-$2000+ range better have a low THD across the board

I listen to a lot of rap in my jeep and i read that rap requires more SPL than SQ so i think this amp should do me fine. I've also heard a lot of good things about the JBL 1200.1. Anyone wanting to comment or share experiences with that amp, please do. Thanks to everyone who replied.
