Hey guys, I want to upgrade my subwoofers the two 12's. Thing is, I'm not sure if I should upgrade my amp too. Here's the amp I have now:

The sub woofers I'd be getting :

The box I have

So should I upgrade right away to a new amp?

 

It'll do ok with that amp, you'll probably want more bass once you get used to it. I'd try to find a computer fan or two to stick on the amp because it'll be working hard with 2 12s.

 

Sicne they are SVC, if you wire them in parallel you will have 2 omhs at the amp. You need to do your research and see if your amp is stable at 2 ohms and what the RMS is. It shows 250rms @ 4ohms.

Each sub is 300rms. You need a mono amp capable of about 600rms.

You have a low end amp. It probably puts out less than 400rms at 2ohm (if it's even stable). The numbers they state are guaranteed to be over inflated.

I would look at a different amp. Class D, mono amp. Hifonics is a good brand (much better than the walmart equipment you have). These are made for woofers and have true RMS ratings.

Yes, it will run but not ideal.

 

Get a real amp. If you're buying pioneer subs, you might as well get a good amp to power it. Plus I would look into a capacitor, it'll help save your battery.

 

How about something like this?

 

Getting closer, especially compared to what you have. It's always better to over power a sub (obviously never use any "boost" on the amp) than it is to underpower.

I would go with this as it has a little extra power in case you upgrade down the road. And 1ohm stable. That is harder to find. But like I said, either of those amps you linked would be fine. I used to be a bit of an audiophile.

Dual Voice coil subs have more wiring options, if you haven't looked into them yet.

 

Sometimes... You can't blow a subwoofer up by underpowering it though. But you can blow them up by overpowering them. Which sucks as you can't really rebuild them.

It's best to just pick what you want now, and stick with subs/amps that match up nicely. And get this too. I even got a walmart one just for you. http://www.walmart.com/ip/Scosche-KP...ng-Cap/4694327

 

the size of the sub has nothing to do with how hard the amp will work

hifonics isnt too good of a brand either
for a good budget amp look into ct sounds/audio technix
a cap is a horrible idea unless your running a bank of super caps


a solid budget 2 12 setup would be 2 sundown e12's on a audiotechnix 800.1 in a custom box

 

Agreed. A single cap doesn't hold enough energy and is too slow. Waste of money for the OP's seutp.

Upgrade your alternator, battery and do the big 3 if you see the lights dimming.

 

Sort of, but you can back the gain down on an over powered amp. You can't get an amp to go higher than it's max gain, which is why under powered amps are discouraged. If you use the "bass boost" on the amp you will get clipping, distortion and possibly overheat the amp causing damage. This is at high volume levels.

Granted if the guy is a 16 year old and just wants to impress the ladies in the high school parking lot, any of the above mentioned suggestions would be fine if you have some idea of what you're doing.

I don't think he'll be entering any SQ or SPL competitions in the near future...
