Ok well my boyfriend installed my system in my car, I will ask him for any advice about it. It didnt take him that long and wasnt that hard to do. I will let you know later tonight what he tells me. Also...amp is decent...nice choice.

well there isnt too much to installing an amp but my first concern is the amp being used and what are its power ratings... can it be brought down to 2 ohm stable... and not just 2 ohm.. and your sub you chose is it a dual voice coil because knowing these things will say everything on how its gotta be wired... because that amp might not of been ideal for the setup unless its a 2 ohm stable or a 4 ohm only if that is the case you can only use half of its designed power

I did a little looking up and your sub you bought says its recomended for 500 watts rms and or 1000 watts peak if that is the case... you either need a bigger amp or a lower power sub
and if you wanna keep that sub.. you need an amp that puts out 500 watts rms a 4 ohm mono.. the one you got is only 250watts and having that much lower.. wont give it much punch or also it will damage the sub over time and also it wont do all the much..
Remember its always better to have more power from the amp than what the speakers are designed for .. but by maybe 5-10% is ideal... so just letting you know
if you wanna know more just IM me or email me.. i can help ya out

[MMaynard]

The amp max is 600watts, but I look forward to your recommendations and thank you in advance

[doobiess]

well max power isnt the rating your suposed to be looking at.. always compare the nominal or RMS watts.. and have them match or slightly have a little more RMS watts on the amp.. for optimal sound

[MMaynard]

What amp would you recommend to go with my ROCKFORD FOSGATE PUNCH STAGE 3 SUBWOOFER 12"

[HellishOne]

Stay away from Sony. You pay for a name not a quality product. Alot of there stuff come with 1200"w" or 1600"w" on the box but when you get down and read the fine print its like 350 watts max. No one says that they cant write a # with a W at the end on ther boxes.

I agree the amp is going to under power that sub big time, but I don't agree with your statments here. Just because it's half then rated max, it won't damage the sub. If anything it'll extend the life of the sub. As long as the amp is putting out clean power (not clipping or distorted) then it's not going to hurt the sub at all.

And as far as getting an amp rated for more than the sub can handle...what's the point? You're just going to have to back off the gain so it won't overheat the sub and damage, so you might as well buy a smaller amp and save your money. It is recommended by most all sub/amp manufacturers as well as installers to get an amp that has an RMS rating in the upper 25% of the rated wattage. e.i. if the sub is rated for 400W get an amp that's rated for 300-400W.

I'm not starting anything, I just don't agree with what you said :)

RMS is what your amp will put out constantly, MAX is just intermintant (sp). don't even pay attention to the max rating...it's there soley for marketing purposes :)
