Amp clipping question?

[RChillin]

Hey guys. I had a quick question on amp clipping. If you can't meet the electrical and amplifier wants to make its power , will it try to make that power with the less voltage and amperage ? And if so can this result in a clipped signal being sent out? My amp used to run fine with barely headlight dim. Now my lights , interior, and even amp leds dim on bass hits. I've turned the gain down scared to blow a woofer (already happened once) and I need to know if maybe getting a 2nd battery could solve this issue.

BTW my amp is fused at 140. I have a 145 amp alt and a crap Walmart batt. Thanks guys.

How much voltage drop do you have?

What's your voltage dropping to? Have you done the big 3?

I have not measured it yet , and no I do not.

Highly recommended and asap.

Can 4 gauge welding wire be used on big 3? Its what i have available at the moment. And should I just take a digital MM and connect it to my batt when playing like full tilt?

Yeah man throw it on there. Anything is better than stock. And yes.

I'd connect the DMM to the amp's + and - power inputs. The voltage drop will probably be worse at your amp, because of the wire's length.

Okay. Ill measure both while im doing it. Then ill PM you and stang the status. Thanks

Alright , sounds good. I can probably get it done this weekend. Ive seen some alt to batt lines fused and some not. Im gonna do that as I want to be safe, but what amperage should I fuse it at?

Fuse to the wire's rated amperage

Fuse to the wire's rated amperage

Thanks man. Would you happen to know 4 gauge welding wire rating? Surely its like 150

No problem. Depends on if its CCA or OFC. I believe most 4 gauge OFC is rated for 150 and CCA is 100.

150 for weld ofc. I fused mine at the alt rating....135. Just a preference.

0 gauge cca is in the same price range and you are getting at least 200-250 amps
