I got the car back tonight and was really disappointed in the bass output of the system. This is my first real audio upgrade, so I wanted to get some more information before I talk to the shop. Setup: Kept the factory head unit (maybe the problem?) Installed Alpine Type R 6.5" component up-front, coax in back Installed Alpine amp Installed sound mat/deadening (maybe the problem?) No sub installed - obvious way to get more bass but I didn't want to go there unless no other options My previous car had some cheap 6.5" Alpines that I got on clearance at Best Buy and could really put out some bass. I also installed a new head unit. There was no amp or sound mat installed. I'd appreciate any input as to why I'm receiving so little bass from the current design. Thanks! |

I'm guessing Phases might be off but that's a rarity. I would though have to say if you crossover on the amp is tuned wrong that will be a huge reason. when I amp my speakers with a woofer I use the high pass filter to tune out bass notes to balance my frequencies out. If you get a over worked installer he could just be stuck in his routine and tune the bass out of it. a proper 4 way set of speakers tuned right should hit almost as hard as if you had 8 inch woofers in the car. From experience though, Alpine speakers suck on bass. their very bright. I have had pioneers be my best source of bass on coaxils. |
