So if I understand this correctly, you can hook up one 4 ohm speaker and it would get 150 watts but if you hook up two 4 ohm speakers in parallel and each one should get 112 watts.

I'm over thinking this: If I want to wire (6) - 4 ohm speakers to a 4 channel amp to just the how do I wire it and what would the impedance end up at?
AMP - Massive Audio BLX4
Fairing - JL c2-650cx
Lowers - Hertz ECX-165.5
Bags - JL c2-690cx

looks like this amp is stable at 2 ohms so front speakers wire in parallel for each channel meaning both right + to the right front + out of the amp, both right - to the right front - of the amp and the same for the left side.
then just connect the rears up normally.

I am new so pardon me if this has been asked 100 times...... How much extra sound can I get from just adding 6.5" speakers over the stock 5.25?? Just looking to upgrade a little while I am trying to decide on a final (lmao) sound system .... and from experience is this a difficult install ?

Will a 50amp inline fuse in the 8gauge power wire from the battery be big enough? I know cerwin vega recemends using 4g wire but was told 8 gauge wire will be fine for my set up?
Its when I want to run sets of the 4ohm speakers with a 2ch amp thats when they would be wired parallel.I Learned something new.
Also learned that the small speaker terminal is + and large speaker terminal is - . Why did harley do that?
Thanks all

Just purchased a RF PBR300x4 amp; American bass SQ6.9 (one of the threads here said they were great for the price). I'm not really looking for anything fantastic, just adding speakers to the lids so my wife can enjoy music while riding.
I'm still deciding if I need to upgrade the fairing speakers...
The plan is to install the amp in the fairing. Then run the lid speakers on one channel and the fairing speakers on another channel. What say the experts?
