Very nice man! I'm glad I shared this deal and am excited to get mine hooked up! If this thread is still active when you get the amp hooked up to your ID mids, let us know how they sound.

If its not 100° tomorrow I might do it then..

Yeah man, I here you there...when I drove home from work today the thermometer inside my car said 104 degrees. Freaking brutal!

My mids are screaming now!! Very powerful amp. Very hard to match gains to my tweets because I don't have a lot of gain to play with. I think I'm at 1/6 or so up. Might need another for my tweeters. But the impact and authority they now have is awesome. I don't think I could go back to how they sounded before

So it sounds good?

I'm buying one with the "$30 off" offered by the Amazon Visa card offer, but I'm not sure if I'm going with the 5002 or the 3502, as it will be powering a single 350w Infinity Kappa Perfect 10.

In either case, either $39 (5002) or $29 (3502) is one heck of a deal!

I would def go with the bigger 5002. Never hurts to have headroom. And yes it sounds excellent.

Can I reduce the gain enough on a 900+w amp to power 350-400w on the sub?

I actually have two Kappa 10's and boxes, but I still want some trunk space.

Should be able too. I actually had a 12 in perfect on 1200ish and be er had any problems. Is it a 10d? The good thing about amazon is that if you don't like it or is too much you can send it back and get the smaller one. But the bigger one would nice also if you ever want to upgraded

No, its the original 10.1 single 4ohm version.

I'll probably just get the 5002, and if I panic about the output just throw in the second 10 and run them in stereo.

Thanks!

Did you end up getting the 5002?

Not yet, still adding to the cart.

Ordered the 5002 along with 100 ft of ofc 14ga speaker wire, total of $72.

Not a bad deal.

Just tune the amp with a digital multimeter to ensure you aren't running too much power to the sub.

1. Typically you would find the square root of the ohm of your driver x the power you want to run to it, however, you are bridging the amplifier so things are a bit different. You'll want to cut the ohm of your driver in half, so it would be 2 x 350 = 700. Then find the square root of 700 and multiply that by 2. The sum is your benchmark number.

2. Set the gain all the way down on your amp and place the crossover setting on "full-pass." If you have any low-pass crossover settings on your head unit, make sure those are off as well.

3. Plug the DMM into the speaker output terminals (bridged of course) and set it to "AC Volts."

4. Turn the gain up to 3/4 volume on your head unit.

5. Play a 40Hz (-5 Db) test tone on repeat and turn the gain up until the multimeter reads the sum of the equation in step 1.

6. Unplug the DMM, plug your sub in and set your low-pass crossovers accordingly.

I'm not trying to insult your intelligence by any means, just thought you might not have known the process based on your previous comment. It's really pretty easy to do any provides some peace of mind.

#2 is confusing.

I understand about setting the amp xover to "full" if I'm using a external xover, but wouldnt I want the gain set with that xover on?

You said you were worried your sub would get to much power. He's explaining how to know how much power your sub is getting by setting the gains to your desired power level. In order to figure that out you have to run the amp full range first.

Hope that explains it a little bit better

Must've been late to the party, only one I found under 100 was the 3502
