So I built the subwoofer box that is all over this site to replace the existing weak subs.... Used the Pioneer Sub TS-SW251 and the Alpine Amp MRP-M350

I have the amp all stuffed in the left side next to the exsisting amp etc. everything was working fine for 2 days, then one night about 1 am I was driving home and the sub stopped playing music....

This morning I look at all the fuses, connections, power light on amp, subwoofer connections etc. All check out ok

When I start up the car or give the amp power initially, the sub makes a pop noise (likes its about to hit for a song/note etc) then thats it, nothing else....

ANY IDEAS.... Is the amp dead or do you think it's the sub....

On the amp, I have the gain at half, been at half the whole time.

Thanks

Michael
