I have two SPS170-A 6.5' In. 40W RMS for my rear door speakers. After being hooked up to a Pioneer Premier amp (60W RMS x 4), i could only hear the midbass from one (no tweeter) and nothing from the other speaker. I have a pioneer DEH-3600P HU. I tried to **** with the EQ but it doesnt seem to be the issue. Any ideas? Wiring?

check the seting on the amp. make sure you set the amps crossover to (HPF) High-Pass-Filter

alright, well the problem is somewhat fixed.. now i have sound on each side but it is just bass...do i still need to set the crossover to HPS? also, would that affect the way my front speakers sound (they sound very nice right now)?

Hook Me Up

no it won't affect the way your front speakers sound. 4-Channels amps have 2 crossovers for the front & rear channels

What model is the amp? is it the GM-6150F?

if you hooked it up right, the front speakers channels are called Channel A and the rear speaker channels are called Channel B. On the other side are the setting. And each crossover are labeled Channel A & B.

Just set the rear speakers (crossover b) to HPF. I bet its set to LPF thats way they sound just bass

Hey i do have that 4ch Pioneer. I checked it out and it was set to OFF. the amp looks to be wired correctly however, when i fliked the switch to HPF, no difference ensued. It sounds the same whenever i flick from HPF LPF and OFF. Do i have to turn the stereo on and off to active the new setting? Any other ideas?
