The best bang for your buck on the market

I owned this sub for over 2 years run off of a bridged RF 601s at 600rms 1800 peak and I must say it is the best sound money can buy. I have owned all different brands, JL, Kicker, Sony, Pioneer, you name it, there is no beating Rockford Fosgate in sound clarity and tone. This is the cleanest sounding sub i have ever heard in my life. I highly recommend, you buy this sub. If you think JL audio, MTX, or Memphis sound great, don't buy this, it doesn't deserve an owner that doesn't know what good sound is.

Great Sub

I had one of these in a q-logic box with a sony 1200 watt amp pushing is really loud but i did expect it 2 be louder but it did have the cleanest bass i have ever heard really nice sound if you want pretty good bass get this one or get 2 of them....i really recommend this sub...and if you ask me rockford is the only way to go for the best sounding bass....

kick a**

i had two of these hooked up to a rockford fosgate t2000 amp and they were absolutely insane, if i would have had them in a good box with correct tuning they would have destroyed my car, they took everything i threw at them and more, i then sold to my friend who had a small car and you couldn't hardly stay in his car they were so loud, well worth the money

Nice Subs

I have two of these hooked up to the Kenwood eXcelon X1200 mono D amp. These things destroy my car. The bass hits real low and crisp! It beats almost all of the systems in my town! I recommend this to anyone who wants a killer setup for a decent price !

Amazing Sub

Got this last week and dropped it in a custom box in the back of my 07 Ford Ranger and this thing destroys!

I have 4 of them with 2 Cadence amps pushing them. They are continuous and unrelentlous! They will leave you with a banging headache of clear and shear power and sound!
