Is this a pic of the amp? Can this be done along with the amp under the TP and with those rear speakers as well (6 in all)?
Your bike looks fantastic!!
Thanks to all for your kind comments, I appreciate them.
Robmay, The red boxes are the Hawg Wired amps. The center one is 150 watts and the other two tye in at 75 watts a piece for a total of 300 watts. The two small amps are called satelite amps....no, not to amplify satelite reception, but to act as alternately located amps. This system all plugs into each other. It is a very clean plug in system that has excellent instructions and is easy to install if you like wrenching on bikes.
I doubt that the factory amp could tye in and add another 75 watts (I think thats what they are?). Personally I don't think you need more.....lets see from 75 to 300 watts. HUGE DIFFERANCE!!!. If anyone is running the 2 channel H-W system, its time to expand that system baby. The speakers in the lowers make it. IMHO, they supply the best sound. I fade the wing speakers down to make the lowers stand out more.
hd-dood supplied me with my goodies and would be better able to answer your factory amp system question.
My suggestion would be to anyone thinking of going with H-W goods and don't want to do it all at once, MAKE SURE YOU ARE ABLE TO EXPAND......cuz yur gunna wanna.

.....BTW Jim, when do I start getting commission checks?
