Expected the Unexpected

I recommend someone this amp to power 1 12" subwoofer. Great sound, great power, very reliable, and no major cons after a month of purchase besides the design, it can be better. If you want a reliable brand for a reasonable price go for Precision power!

great little amp!

I ordered this amp to power my 12" kenwood performance series sub and it bumps! After a shipping error, the customer service department helped me out and rushed the correct thing. I got the correct product in a day and they told me to keep the cables they sent me originally as a sort of gift. I really enjoyed my experience with sonic electronix and this amp is exactly what i needed to power my sub. I've had it installed for over a month now and have had no problems.

Good bang for the buck!

I bought this little amp to replace an Orion Cobalt amp that died. I needed something with a very small footprint. This little amp does the trick. I Don't think it sounds as "smooth" as the Cobalt, but at least it hasn't died! The power and ground wire inputs are "straight in" which is better than the angled ones on the Cobalt. I bought some Stinger adapters anyway, for ease of installation and future de-installation. I would recommend this amp.

Nice amp for the price.

Nice little amp for the price. It's not a powerhouse, but powers a single 10 or 12 nicely.

Amazing little amp

I recently downsized my heavy 2400W system in my Charger but still wanted some punch for everyday. Price/watt was what attracted me to the i450 but I wasn't expecting much. I ended up going with the Precision Power i450.1 and a dual 4 ohm 12" Rockford P2 and this little amp pushes the P2 just fine, I was very impressed. The small footprint is a big plus, it's about as big as a game gear (for those who remember those) you can hold it one handed. Looking for something with decent wattage for cheap, pick this up.

Good Power in a small package

This amp was picked for its physical dimension ( because of the small space I had to install it in) and it was a little over power to help with any heat issues. Once installed and connected. This little amp put out good smooth power... Had all the adjustments needed for decent tuning ability. I would recommend this to anyone needing good power for the price with limited space to work.

Perfect little amp

I purchased this amp to power my Alpine SBR-S8-4 8" ported box sub. First off, that sub is amazing for how small it is -- but it's powered by this little precision power amp which matches it perfectly. It's 260w RMS and the Alpine calls for

Amazing

As you can expect from Precision, superb Quality. Powers my x3 c124 kickers with no problem. Speakers are in my trunk and my eyes vibrate, i can literally feel my organs vibrating. I have operated this amp for over an hour and it held up in 95f weather, North Carolina. Really cant ask for more. Provides the power and can take the heat.

Works very well.

What can i say, it works exactly how it should. It is powering my 3x 12inch kickers. I have been messing with the dials, and my stereos settings alot. Ive blown the fuses on the amp multiple times. Which is a good thing!, this bad boy has saved my speakers a few times. It protects my speakers and provides the power needed.

Really cant be any better.
