Soon im doing a blowthrough in my 97' single cab s10. I need an opinion on an amp to go with the 18" Fi car audio btl. I was thinking of the rockford fosgate t20001bd. I have no idea what amp and how to wire it right to get the right power to the sub. With that amp i would wire it at 1 ohm. is that the best way to go. I know if i wire it up at 4ohm i need alot bigger amp... any suggustions.

grab the dual 2 btl, and wire it pos-pos, neg-neg,

Would that amp be a good one then?

The amp i mean?

Also with running that amp how many batteries and what alternator should i use? I plan on 1/0 gauge wire. I want no problems lol...

RF T20001bd will be a good match

yes that rockford t2000bd would be perfect for it

why the 2ohm over the 1ohm ?

why the 2ohm over the 1ohm ?

Because you can only wire a DVC1 ohm to .5 ohms or 2 ohms. And since most amplifiers make the most power at 1 ohm... those final impedance figures don't help you much.
