Zapco ck9.0 4ohms version $850 OBO 2200w bridged at 4ohms Competition SQ amp. Condition 8/10 due to some scratches. Functions perfect. specs found link below. All specs are exact same with the exception that this amp is older 4ohms version and won't do 2ohms bridged or 1ohms per channel. Specs http://www.zapco.com/prod/comp_prods/c2k90Frame.htm

Box design is exactly what you need to gain some spl. But if you're looking for easy peak gain in spl for a competition make your sub wiring so you can easily wire amp at .5ohms not for music but for a "burp" of your peak frequency. If it protects when you unpause the radio full tilt then trying rolling volume. If you have an alpine radio there is a feature in the radio that does this for you automatically. If you don't have that option go buy a Soundgate LC-1 which is a in line volume nob and run that in line of your rca to the amp and you can manually roll volume. Going from 2ohm to .5ohms for speak spl on a 7k2d is probably over 2db gain. But if this is just for music then you need to build a louder box. Listen to nightshade.

We need different impedance and since it would be a shame to cut up like new subs I want to see if anyone wants two perfect condition 3 month old 9515G dual 4ohms with 8" carbon fiber dust caps. Killer subs and loud as hell. $450 EACH. Expect shipping to be about $35-50 each since they are 60lbs. And if anyone knows this is a killer price. Feel free to ask any questions.

Yes it's available. Let me know.

No Trades: All items are as seen in pictures. Sorry Dynaudio sold Four Polk Momo MM6 drivers with two x-overs. Drivers and x-overs work 100% $150 for all TWO BRAND NEW NEVER BEEN USED PIONEER Premier x-over $35 One Polk MOMO tweeter $10 One Diamond Hex tweeter $10

No trades need to upgrade to 6k2d. Used the past 2 months and in mint condition. 4200w @ 2ohms @ 12.6v and 2800w @ 4ohms @ 12.6v NOT 1 OHMS STABLE Highly recommend an 200+ amp alternator along with two good batteries to see rated power. $700 firm not including shipping or ppl fee.

Good condition Orion 8004 4 channel. 100wx4 $200 obo

Strong clean amp. I just installed mine recently and clamped power at 95w per channel at 6ohms on 4ohms speakers with voltage 13.3v. (my battery has a bad cell)

Stetsom made the amps for them.

I highly don't recommend them down to .25ohms especially with limited electrical. It puts a lot of stress on the amp and voids warranty. Not saying it can't do it for burps with proper electrical but like any amp puts stress on it. But .7 ohms no prob and sometimes even .5 with right impedance rise and electrical.
