Damaged Subs/ Underpowered, Affect performance Options

[Flyinghumanoid]

I got two Audiobahn AW1251Q 12" Subs from a friend and they have some wear shown in the pics below. I was wondering if these little scrapes in the foam surround will effect how they sound. They dont go all the way through the foam, just a little off the exterior. And there are more of them than in the pics, I just showed the biggest one for example. Also, the amp that he gave me with the subs is a DB Drive pd300 platinum series. I found that this is only a 300 watt amp, but the subs are 400 watt rms. If the subs are 400 watt rms and those scrapes wont effect the sound then I guess I need a different amp. If anyone has some experience with scrapes and could give some amp recommendations that would be great. Thanks.
Here's the pics.

Daul 4ohm - Daul Voice Coil (or DVC.) As a single sub, the voice coils can be wired parallel for a 2ohm load, or in series for an 8ohm load on the amp.

Since you have two subs, it can be wired so it puts either a 1ohm load on the amp or a 4ohm load.
Since that amp probably does not support a 1ohm load, wire the subs as shown in this diagram -


You may have to take the subs out to see how they are wired inside the box.

Did a quick search and it looks like that amp puts out 150 watts rms at 4ohms, so set your gains accordingly.
