Using overpowered amp for car subs?

post #1 of 13
Thread Starter 
Can I use a VERY overpowered amp for two subs in my car?

Theres a deal on Craigslist for a 1200W RMS mono channel amp. JBL GTO1201.1ii to be exact. And I was going to wire two subs rated at 200W (RMS) each, totaling 400W. So the amp would be 3x more powerful then the subs.

Because to get 1200W worth of subs would alone go over my budget, not including the amp. And I have a very small 2-seater car, I dont need all that power. This amp was just $100 and is a great deal. And would be nice if I upgraded to a larger car and subs later.

You will not blow your subs, you need to correctly set your gain and headunit settings (not to mention have some common sense when playing music). Believe it or not it is actually good to have a more powerful amplifier to avoid clipping with a weak and cheap amp.

The amount of power going to the subs will vary based on the gain in the signal. The amp doesn't always send 2kw to the subs also is wattage ratting based off the same impedance as the subs cause some companies will base there wattage ratting off the impedance that nets them the highest wattage. If your smart and know the limit of the subs and not a dumb ass you can use the amp without blowing them but most people can't limit themselves and would blow them with this setup.

lol yes i know this.

i worked installing car audio in HS.

I work part-time as a live sound engineer and interned for years at record studios.

obviously you can use the gain to make it work, but it would be a complete waste.

it's like getting a hx1000 to run a amd socket a cpu and a fx5500.

sure get the amp if you have plans to get better subs later, but if you're going to keep that setup, it's a waste.

I would say if theres a deal on it and its cheaper or a little more to get the biger amp then he should go for it just be smart. It would leave some head room for later. I personally think most car audio is a waste i dont spend much time in my car so i would rather stay in my well tuned studio or be running my PA for an event.baaasmiley.gif

The truth in this thread. Spend thousands for a substandard sound stage and imaging ... no thanks.

@ OP: If you can get the amp for a great deal go for it. Just be careful with the gain (and hopefully you know what distortion sounds like).
