Hey guys,

So my dog ate my 8" Monoprice subwoofer.
The amp and internal wiring is OK,but the woofer has been eaten.
(He ate a candy cane, or 5...off the xmas tree and went NUTS)

So anyway:

I have in my garage an 8" JBL GTO subwoofer that I used to have in my car:
This one: http://www.amazon.com/JBL-GTO804-Reduced-8-Inch-Subwoofer/dp/B000FHAXPA/ref=sr_1_1?ie=UTF8&qid=1358439639&sr=8-1&keywords=8%22+jbl+gto

Could it be a drop in replacement, or would I have issues with the stock monprice amplifier?

One must use speaker modeling software to determine the suitability of any driver/box combination.

I know the cu ft is OK.
Here are the specs:

Quote:

Audio Specifications
Nominal Impedance 4 ohms
Peak Power 800W
Frequency Response 30Hz–400Hz
Sensitivity (2.83V/1m) 91dB
Power Handling (Peak) 800W
Power Handling (RMS) 200W

I cannot find anything on the nominal impedance and sensitivity for the monoprice stock subwoofer.
I know its 60W RMS though so it should be OK.

So its not a simple yes/no?

I figured the only thing that I need to worry about is the ohms? Then again, I am no electrical engineer....

Just found this so I guess it won't work:

Quote:

car stereo systems run of 2 to 4 ohm impedance. home theater systems run on 8 ohms. if you connect a 4 ohm speaker to a 8 ohm home stereo you will overheat the amp and burn it out. to fix this problem, hook your two 4 ohm 12" subs in series mode. to do this, connect the positive on sub #1 to positive output on the amp. take the negative on sub #1 to the positive on sub #2, then connect the negative on sub #2 to the negative on the amp. by doing this, you have converted your two 4 ohm subwoofer speakers into one 8 ohm load which the home stereo amplifier can handle.
