Fairing/Lower Speaker Help
I finally got my SoundStream Nano520 amp and installed it this weekend. My old amp was a Rockford 4ch 4ohm amp. I have a Sony DSX-S310BX. I had a set of 6.5 inch Focal PC speaker in the faring that was connected to the front ch. and the lowers had a set of 6.5 inch Focal PC that were connected to the radio's amp. I had a set of 6x9 Pioneer TS-D6902R in the rear saddlebag lids connected to the rear ch of the RF amp. The front speakers sounded good when connected this way. Now I have the 2 sets of front speakers connected parallel to the front ch of the SoundStream amp and the rear 6x9 speaker to the rear ch. Now the front speakers do not sound as good when they weren't in parallel. It seems the fairing speakers had more bass. I have them packed with ployfil and the amp is set for AP for all pass middle position on the amp. Do you think I should connect the fairing and lower speakers as I had them with the RF amp or do I have something wrong with the wiring of the SS amp. I have the new style SS amp the one with the speaker block on the right side. I connected the fairing and lower speakers by taking the pos. of both speakers and connecting to the pos on the amp and the neg. of both speakers connecting to the neg. on the amp for the left and right front ch. What should I do to get the bass back as before? Overall every things sounds great except when I fade to the front speakers only. I forgot to mention I have a set of Hawg Wired tweeters with crossovers installed in the fairing replacing 2 gauges.

Not familiar with the ohm rates of your front speakers, but I'm willing to bet when you wire the tweeters in they are messing with your sound.
Also, have you set your gains with a digital multi meter like Ultanutz has posted in the sticky?
I just finished up a similar set up to your's. I have four Polk DXi650 speakers wired in parallel to the front left and right channels of the SS 4.520 amp and two DXi690 6X9 in the saddle bag lids wired to the amps rear left and right channels. The sound is AWESOME!!!!!
I used the procedure in the sticky to adjust the amps gains.

08, sounds like you got it hooked up right, S.S. in parallel should be pushing 260 rms to your front speakers. The way you had the R.F. wired you were pushing 75 rms per channel to the fairing speakers, now your pushing 65 rms per channel to the fairing speakers that might be the difference? Also I don't know what the tweeter pods are doing to the ohms being seen by the S.S. amp, are the tweeter pods wired to the HU or the amp?

Same procedure, just do it twice. fade all the way to the front and follow the procedure, then fade all the way to the rear and follow the procedure again. Make sure you're setting your bass/treble/eq to flat and not all the way down.

I would however disconnect the tweeters, set your gains, then when you're done setting your gains, hook the tweeters back up.

Ok... I will set the gains again. The front speakers are loud and no distortion now. They just don't have the lows as before. I will also check the wiring. Then I will try unhooking the 2 sets of front speakers and just connect the fairing speakers to the SS amp.

re-reading this and thinking... if you have more bass response by using just the fairing speakers than you do with the lowers and fairing speakers connected together, then something is wrong here. Might want to double check your wiring to make sure you're not running speakers out of phase (wiring backwards on one or more speakers)
