Subwoofers clipping and popping (no music) after new amp install.

[Neal301]

Hey all,

I am currently trying to power two earthquake sws8xi subs (150w rms 300w max) in my 2011 3 series. I was running a jl 500/1d amp originally at 2 ohm and it sounded like **** so I bridged it to 4 ohm, the drivers side sub was getting crazy hot but sounded great.

I purchased a rockford p300x2 amp rated at 150w rms at 2 ohms, however it came in at 225w per channel rms. I hooked it up and my subs dont even play, they make this strange popping sound (im assuming this is what “clipping” is?) at volume above 1/4. They play when it is very low. Are they simply overpowered? The hell is going on?

You probably have it hooked up incorrectly. Completely disconnect everything from the amp and start over making sure everything's right.

If that doesn't change anything then take your subs out and check them with a dmm. They may be blown.

I'm curious how you "bridged" a monoblock in the 1st place?
and... no... a P300.2 shouldn't be "overpowering" pretty much ANY pair of subs Imo.

sum ting is wong... I agree

Btw... earthquake sws8xi is a 2ohm driver I think, earthquake sws8x is 4ohm... correct me if I'm mistaken
And that ^^^^ leads to more questions...
