Amp or Sub Problem?
Hi! I just install a sound system in my truck (2005 Dodge Ram Regular Cab) my friend and I put new speakers (Infinity kappa all around) my friend sold me his amp (Rockford Fosgate P500-2) and let me borrow his sub (10" kicker cvr with a bazooka box) when we set it up it sound great for a few days. Now i just bought my own subs (2 Infinity Kappa 100.9w subs) and now the bass sound crap. So, I decided put my friends sub back and it still sound like crap. The subs are good shape but some how the amp gets really hot (kinda burning my fingers). Does that mean is over heating and should I need a new amp?
I've been messing with the amp settings and I can't get it right. What should I do?

i think the amp is done! remmember you were using a bazooka bass tube and now you installed 2 woofers. i think the amp is trying to keep up with the woofers but is too much, that is why is over heating!!!!
Sounds like you might of fried the amp, but first check the ground. Where did you ground it to? If its not grounding very well then it can overheat like that.
(and btw, the amp puts out what it puts out, the amp wont try to "keep up" with the subs, its the other way round

How are the subs connected to the amp? Are you trying to bridge that amp? Those subs are selectable 2 or 4ohm. If you select 4ohm and bridge the subs, you will get a 2ohm load on the amp and it is only capable of a 4ohm bridged load. That may be why your are overheating it. Def not good to keep it like this. If you have the subs on 2ohm, you can wire them in series with each other and then parallel to the amp. You gotta make sure your wiring is 100% correct when doing this or you can fry the amp.
Best thing you can do is wire them up as normal on their own channels to get 250x2, but you'll need to put the selector switch at 2ohms to get that power, which is the same power as if you bridged the amp.
Another thing, make sure your wires are not reversed. If you have one sub's polarity swapped, your bass can almost sound non-existent.

Ok! I check all the wires and their all ok, the ground the power everything and their ok. Now I just bought a box for my subs and they sound great. Now every time I raise the volume to high the bass doesnt respond to the songs. So, I'm pretty sure the amp doesnt have enough power to handle my subs. What amp should I get to get good solid bass and sound for my subs? I'm not the kind of guy to have to much bass that rattles my car, I listen to metal and some old skool hip pop (Metallica, Slayer, Bonethugs,Biggie smalls etc.) but more into metal lol. Any suggestion!
What are you runing for a Headunit and what cables/connections are between the amp and radio? Do you have the OEM HU and are using line converters? Aftermarket HU and just RCA's straight to the amp??? lemme know what u got.
Here's the story. When i bought my truck it already came with an aftermarket headunit (Sony Xplode idk what model number#). The RCA and the HU cable was already there. From my headunit to under my seat. I install new power wire ( sorry idk what is called) and fuse to my amp. I just put the HU and RCA straight from my headunit to my amp (most likely I just plug and play). And for the coverters idk. So, what's the deal here? Is it the cables or is something else?
