the audiopipe is a decent amp for the price. not the cleanest power but if you set your gains right you will have no issues and also will have a warranty for 1 year. i hate to say this but the audiopipe is proly puttin out more rms than the power acoustik mentioned above but its up to you. i know somebody who is running the audiopipe 1500 at .7 ohms and is workin just fine. good amp for the price cant beat it
