I need Help on 2 things

[smggolfer]

OK, I have 2 pioneer 10" subs and a prioneer 200 watt amp. They were working fine and then one of them blew and is now getting fixed. In the mean time i am using a Jenson 400 watt amp and 1 sub and 2 6x9's. Since using this amp and changing the fuse on the battery i have noticed that my lights dim when the bass hits. I put in my 200 watt amp and it did it again even with just the 6x9's and it also did that. I had my battery checked and my alternator. They are both fine. When i changed the fuse on the battery for the amp kit, i think it had a 40 amp fuse and i went to radio shack and got one they said to put in a 60 amp fuse. Would that make a difference?

Now my second problem is that i hear my Rpm's in my 6x9's... i read that its an interference but im not sure how to fix it.

Thanks in advance.

Either way you describe it , sounds like your auto's electrical system is lacking power. You can install a capacitor for a quick fix but I would suggest upgrading you alt.

As for RPM's in your 6 X 9's, motor noise can come from many things, ex. Bad grounds, signal cables run with power cables, to many possible causes to list. Are your 69's run with amplified power?
