Your speaker are hooked up wrong.or there may be dust in or on the terminals.i used a q-tip with rubbing alcohol and wiped them down.hook up the speaker cords properly and try this again.if this does not work then unplug the stereo and let it sit overnight and try again.

Ok i just got the sub from a sony sswg450 i want to know is there some way to hook it up to my Pioneer home Receiver


Did you get a manual with it? According to the Sony site this speaker originates in Sony MHC-GX450.

"This product bundle includes the following models:
HCD-GX450 - STEREO MINI SYSTEM
RM-SC3 - REMOTE CONTROL for Shelf Mini Systems
SSRG444 - FRONT SPEAKER FOR MHCGX450
SS-WG450 - SUBWOOFER FOR MHCGX450"


Find the manual here and learn a bit about your seprated sub...

http://esupport.sony.com/US/perl/model-documents.pl?mdl=MHCGX450

See page 7.

As can be seen, the subwoofer has two connections to the mothership, very unlike the standard speaker level (+/-) speaker wire or RCA-Line-Level subwoofer out that 'normal passive or active subwoofers use, respectively.

Not knowing which of those your unspecified Pioneer receiver supports, it is impossible to say. Does your Pioneer have that control jack?

Mini-systems are generally not designed to be pieced out and used with grown-up gear. The absence of standardized connections is the clue.

Why do my sony mhc-gx450 cd shelf system power lights keep blinking


This usually indicates faulty wiring, or miswiring. Disconnect the wires, one set and turn the unit off and on to see if that elimates your problem. If it does, the wiring or component is at fault. If you disconnect everything and have the same problem, it's an internal fault with the unit and will have to be troubleshot. Get and estimate first, to evaluate whether or not it's economical to keep, or replace with a new one. Good luck, hope this helps.

My left speaker to my Sony HCD-GX450 stereo is


Make sure that Loudness switch is turned off & bass is not boasted up. Most cars have small cheap speakers that can't handle the bass. also its better to cut the low frequency from the woofer using a passive or active crossover. Most nowadays head units have got some sort of built in crossover. Refer to your head unit manual.
