I bought A brand new IDA-x001 Alpine head unit and 2 pairs of Alpine sps-600 speakers and the sound quality is not very good. I get barely any bass, if there is any at all and the sound can get pitchy sometimes. I have a 12" type-E woofer that does a pretty good job with bass. But with just the speakers on, it sounds pretty bad. I dont understand it at all. There are pretty decent speakers with 240 watts max. The 15 watt stock speakers had way more bass then these do. WHYYY?
What do you guys suggest?
