Default Stock Amp question

At first i thought that the 10 speaker bose system would kick pretty hard with bass but come to find out the "sub" above the spare tire is simply a 6 inch speaker. The amp, as i read from other threads, i found under the passenger seat all bolted in. Would it be possible to run that to another amp to power an after market sub. I started building a custom shallow mount sub box for the back corner of the hatch and just want to know if i can string off of that amp (seeing as it would be the least amount of wiring). Anyone done this or know if its possible.

If you are asking if it would be possible to hook up an amp using the speaker wires that was leading to the stock “sub”, the answer is yes. However, you will need to make sure you either have (1) a high-low input convertor or (2) an amp with high level inputs. Now the question really is, what type of signal is coming from those wires. Are they already crossed over to only produce the certain frequencies that can be handled by the stock sub?

For example, let’s say the stock sub is only able to handle frequencies between 100 and 250 Hz (fairly normal range for 6 inch speakers). The stock amp, knowing this, sets the cross over to only send that frequency through those wires to the stock sub so not to allow that sub to attempt to produce a sound that may damage it. You hook up an aftermarket amp for a new sub. Set the crossover to 100 and lower (which would be ideal for a real sub). You turn everything on and what do you hear? Crap.

That, of course, would be your worst case scenario. Your best case would be if the signal isn’t crossed over at all (full range) and you can do your cross over adjustments using your aftermarket amp. But since this is Bose, I can almost guarantee you that isn’t the case. The best you can hope for is the stock amp is set with no low frequency limit. Like if it is set to produce 250 Hz and lower.

Let me know how it this works out for you.
