I couldnt find any reviews on sites that sell this so i figured i would ask on here. I plan on getting this to power a 12 Type R or a 12 L7. I found it for just around 80 dollars. It would be 400 watts at 1 ohm, i think. I talked to my brother who hooked up my last system and said it would work that way. Thanks

That amp is NOT stable at 1 ohm! Now if you get a dual 2 ohm Type R then you can wire it series to a 4 ohm load which would give you 400 watts with the amp bridged. Also, it's a class a/b amp so it's not very efficient, it's going to put out a lot of heat. In any case this amp will work as long as you get the dual 2 ohm model Type R or L7. In all reality SAVE up some money and get a quality class d mono block amplifier that puts out at least 500 watts rms @ 1 ohm! You will be so much happier than rushing into buying a crappy amp!

Sorry i meant to put the 4 ohm bridged you mentioned. Thanks for the reply. The only reason im looking into buying this amp is i had a 250 watt hifonics son of thor amp that was great. That amp is discontinued and i cant find it anymore.I talked to my brother who hooked up my last system and he said i would need the dual 4 ohm sub to hook up to that amp bridged. Do you reccomend an amp that is faily cheap. Im a very cheap person and this was about all i wanted to spend, lol. As you can probably tell, im not the smartest person on this stuff. Thanks

Well like I said, that amp will work. That amp is by no means the greatest but since your on a budget it'll be okay. Your brother is wrong though about the sub, you would need a dual 2 ohm sub. Dual 2 ohm woofers can go to either 4 ohm or 1 ohm and since you would have to bridge that amp into a 4 ohm load you would need the dual 2 model. Dual 4 ohm woofers can only go to 8 ohm or 2 ohm.

This is for a dual 2 ohm woofer:

This is for a dual 4 ohm woofer:

I have a similar question; i was looking at the same hifonics amp to go with a kicker 07CVR124 sub. If i bridged this amp would it be able to handle the 8 ohm load the sub would put on it, or would i need to get the kicker 07CVR122 (which is the same sub but with 2 ohms per voice coil instead of 4)?

Yes, the amp will do the 8 ohm load. The power output on the other hand would be pitiful. Pretty much take the power output @ 4 ohm bridged and divide that in half to get what the amp will probably put out @ 8 ohm. I would recommend getting the dual 2 ohm model so you can wire the sub to 4 ohm and get the most out of the amp.
