Rockford Fosgate Punch PPB1

This bass knob came with my rockford power 1000 5 channel and operated good. I didn't know much about car audio at the time, so gains and bass boost was off. I ordered this knob seperatly when i sold my amp ( only because i diddnt feel like taking out the seats and console to fish the wire out) and recieved it very quick. I will recommend Sonic Electronix in the future.

I bought this to tone down the bass if needed in some songs
It only changes volume a little I don't thing it changes the Hz at all and the blue light is too bright I had to put tape over it

I am using this with an RF P2002 2 channel amp and it works great. For some reason, the P2002 is the only amp in that lineup that didn't come with the bass boost knob. I was originally using the amp for mids and highs, but now I'm using it bridged to power a single 10" sub. The bass was there but a little weak until I hooked this bad boy up.

Sounds like a different amp now! Highly recommend this if you have a P2002 amp. It makes a huge difference!

would definitely recommenced this knob if used correctly helps out a lot at peak frequencies.

I would recommend this to anyone who wants a little more bass from their system. I bought this for my RF P1200.2, it's powering 2 Fi SSD 12's and i cant turn the bassbost more than 1/2 way before my ears start hurting, of course i don't recommend you leave it there for a long time, i just use it to show off my system to my friends.
