Orion 250 hcca rated 50 w. per channel, 2 channels. Stable to .5 ohm load. bridged. Woofers, Kicker cvr 15 in. all coils 8 ohm in parallel. Giving me a load resistance of 2 ohms. since the amp is running bridged, the load would be @ 1 ohm. c thats a calculated wattage of 200 w. per coil. total of 800. give or take.

Heres my delema ported or sealed. i have no exp. with th kicker cvr's. my calcs. are not accurate or any suggestions/ comments would be helpful. the vehical is an 71 VW Bus. this is what i have to play with.

Any q's or comments please drop a line.

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

if your looking for a lot of boomy bass you should go ported. if your looking for more sound quality, you should go sealed.

While I do not recommend it, I have PERSONALLY run that amp (and the little brother 225HCCA) at .25 ohms (bridged into .5 ohm) with forced cooling. Additionally, the manufacturer specified it to safely handle a maximum load of .5 ohms per channel (bridged into 1 ohm).

Without allowing for losses, which become SIGNIFICANT at that kind of load (around 10 to 25 ADDITIONAL percentage points), your amp, bridged, will provide approximately this much power:

400W @ 4ohm (realistically, 350W)
800W @ 2ohm (realistically, 700W)
1600W @ 1ohm (realistically, 1250W)
3200W @ .5ohm (realistically, 2200W)

These are bridged load numbers, but even bridged into a one ohm load, that is still an EXTREMELY capable amplifier. Bridge the amp into your 2 ohm load, sealed enclosure, and all will be happy. MAKE SURE you do not cover the amp with anything, as they weren't known as "Fryin' Orion" for nothing! posted_image

At that kind of load, they will run quite warm!

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."
