Which amp?
 

Looking at getting 2 infinity reference 1250W subs. Its 300W at 4ohms each sub. Anyone know what amp might be best for this but not looking at spending too much.

i wouldnt get those subs personally, would be better off getting 1 good sub, as opposed to two not so good ones

read the guide in my sig

alternatively, buy the subs, and search ebay for a JBL 7001 monoblock which produces enough power to run the subs
