Hey all, Question for you guys:
I have a subwoofer and amp setup that i have had in 3 different cars now. In my past two vehicles the woofers slammed, and sounded great. On my current vehicle however I have run into problems.
Issue: The output of the amplifier is very low. The gain has to be maxed out in order to obtain even a low level of bass, but nowhere near what they should be. The Rear/Sub output is set to Subwoofer, the sub level is set at 80hz +4 (out of 6). The phase is set to Normal.
I have an old MTX Thunder 6500D amplifier hooked to two 12" MTX Thunder series woofers (newer woofers). This setup was in my old car and worked great, the only difference between my old car and new one is I bought a new head unit.
I have tried, different woofers, a new RCA cable, and all the possible settings on the HU. I have even opened the amp and inspected both sides of the PCB for any heat damage, or missing components. I have found nothing wrong.
I installed everything perfect, Nice big ground thats bolted to a bare metal area of the chassis. Upgraded the car's chassis and engine grounds, and used 4 gauge wiring to the amp. The RCA's are brand new, and the headunit is also brand new (pioneer DEHX5500HD). I have been doing installs since i started driving (10 years now), and have never had this much trouble with an amp setup.
The only thing I have not tried is a different amplifier. I dont have one handy so im trying to cover all my bases here before i go out and spend money on a new one. Any ideas or tips would be appreciated!
