Overpowering sub?

Hey, i was wondering how bad getting a new amp, (that will run around 500rms) and tuning it properly to run on a sub thats rated at 300 rms.... Would that be okay for the sub if i set it up properly? The reason i am wondering, is so that any future upgrades to the sub would be much easier, seeing as i woudlnt have to go get a new amp aswell. Also, im running an amp that only delivers 200 rms to that sub, so i wouldnt mind a little more for now.

Thanks,
steve

over powering is always a good idea!... its always good to have some head room with amps and this way you can reach the subs maximum potential with out getting a distorted signal from the amp

yeah, you shouldn't have a problem. Just keep in mind that the amp is capable of frying the voice coil if you give her everything for too long. Please keep you gains low as well, it's better to use the entire volume range on the deck to get to maximum output, than to get there by 1/4 volume...the last 3/4 is the clipping and blown subwoofer portion when the gains are set improperly.

Why do people always say "set gains low." ????
This makes no sense to me i suggest you set the gain PROPER not low.
You can power that sub with a 4000 watt amp if the gain is set PROPER.

sorry Hannibal, the idea i wanted to get across to him was to not over do it with the gains, as many do. I agree you can power any speaker with any amp if you set the gains "properly" and use your brain to control the volume.

Super. Any ideas on which would be more appropriate to buy... clas AB or class D, for my shallow mount sub?

Is it a svc 4ohm or dual 2 ohm or dual 4 ohm? It makes a huge difference.

You are not planning on running a lot of power, and can get away with a bridged 2-channel AB amp, as long as your sub's final wired load is 4 ohms, if th eload is 2 or 1 ohm, than you really have no choice but to run a D amp, which gives maximum power output at your sub's final impedance.

Also, if you're overpowering, the sub enclosure plays a big role. The bigger the box, the more efficient the sub becomes, therefore, hiking the chances of sub's overexcursion, but if the box is made to the sub's recommended enclosure specs, then you're good.
