i was wonderin if i could get more bass or make it louder without buying an thing like would bigger wires help?
Bigger wires won't help. If you can't increase bass within the receiver's settings, or if you have a subwoofer, and can't get more bass by turning up volume, with knob on the back, you'll just need a bigger and better subwoofer. You haven't given any info about your system. It's hard to say for sure, not knowing what you have. If you don't have a subwoofer, the speakers you're using must not have good enough woofers in them, to satisfy you. If you have a Dolby Digital surround system, go into your receiver's setup menus, and set your speakers to "Large", if you don't have a subwoofer. If you do have a subwoofer, set the speakers to "Small", so all the bass will go to the sub.
would a better reciever do any thing cus im using some 15$ sony it works nice with my antique 18's but i know they have more capability than what there doin
