I have 2 10" subs (Boston Acoustic G110PD) hooked up to an Alpine MRP500 amp and ran to a Pioneer DEH01300MP headunit.
My problem is that the bass is sloppy and sometimes hardly hits. It seems I either get crazy amounts of distortion or no bass at all, no matter what the amp is set at. I only seem to get bass when I set the headunit to the loud mode but I don't like doing this because it makes my door/rear speakers sound very poor. I have a few theories but wanted some advice before I take it into the local car audio shop.
My first theory is that my headunit is the problem- when it was installed we bypassed the new headunit amp and just tapped into the stock amp (2000 mustang-bad stereo) because we didn't get the right harness in the mail. I considered taking it into the shop to get it all hooked up correctly to see if maybe the stock amp head unit amp is the culprit. (New headunit or just getting everything rewired)
My next theory is that maybe I have a terrible set up. But I feel even a poor set up would have much better bass than what I'm getting. The subs are 400 rms at 2 ohms and the amp is 500 rms at 2 ohms so it couldn't be a lack of power. Is there a chance my amp just isn't going to 2 ohms and is sending 4 ohms instead (300 watts)?
I'd appreciate any help I can get!
