Easy

Just What I ordered and Just what I needed very happy

Rockford Fosgate Punch PPB1

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

One of the few places you can find it!

The remote that came with my amp, P325.1, broke and this was the picture perfect replacement. I couldn't even find the older 2 knob model anywhere else! Awesome find and great deal!

Works kinda

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

Night and day difference.

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!

bass knob

I made an inquiry about a dual knob that was out of stock. They were very prompt in informing me when it came back stock and shipped it very fast. Will buy from again thank you for the good business

RF PPB1

Works as advertised. Blue LED is too bright though. Good product overall and sonicelectronix is the cheapest ive found it.

Works great!

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.

Worth the Money

I purchased this device to accompany the amp I have and I am impressed with the sound range it gives my system

nice

this switch really helps out, instead of running back and forth to the drivers seat and the trunk. you can adjust the htz and boost in the drivers seat! should have came with the amp though

ok

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.

Rockford Remote

I would recommend this product, it works with both my Rockford Amps and it is easy to use and there to change the settings at your fingertips

Hard to find / obsolete

It’s specific to an old school T1000db.
I’m more impressed with sonic having it in stock and they shipped the same day!
Sonic is a good find!!
