I had a rockford 550 amp going to these and they were amazing. Given that I would blow them every year. I wanted to go P2's but skipped it and went to L7's. Great sub as long as you got the right power to it. I had too much, so that was my mistake. But compared to any other brands low wattage subs, these are by far the best. I could be wrong because I had to much watts rms going to them but still liked them. Remember when you purchase something and especially beat, you get what you pay for.

Even though this is only a 250 watt sub. If you hook up two of these, then you'll have a pretty good amount of bass. I defiantly wouldn't run these over 300 watts of constant power. Very good sound quality excellent. And my favorite part is that this sub isn't to particular with the size of the enclosure. As long as it's pretty close to what it's supposed to be. Unlike Alpine type r's where the box has to be perfect for the sub otherwise you wont get the best performance you can.

These things pound in a sealed enclosure with a little amp, with a big amp they pound with a ported enclosure. I used to own 2 p1s4-10. But then i decidedi needed to upgrade my system. i would highly recomend these if your looking for some hard hittin bass in the trunk.
(P.S.my friends are jealous of these)

These subs see definitely a crowd pleaser! I have two in my trunk and I love watching people's faces light up when they hear them!

This sub is great for the money, clean bass in a sealed enclosure, but if you were wanting a good thump with it, upgrade to a p2 or a p3.

Great sub if your looking for a good kick that doesnt drown out the music.

I have 2 of these and they sound amazing for only being P1's. They sound way better then most of my friends systems. They're great for the price too. Love them!

I have one of these in a ported box running off a p300-1, i have the 4ohm woofer. To start off with do not, i repeat do not over power this woofer it will fry it instantly. Hooked a t1000-1bd and it lasted 15 min. The woofer would get extremely hot just on the p300, and would distort after a good hard 20 min of playing, the woofer has great mid and low bass but the deep stuff is just out of its league. I know what your thinking well ya its going to fry on a t1000 but i put a sundown sa10 on it and it played for months.

I have 4 of the p1's wired down to 1 ohm on a kole 7000 class-d amp and all i can say is wow.

This was my first sub woofer I have ever got for my truck and I was very pleased with its performance. I paired it with a kenwood 350watt amp. The sub was way underpowered. It was only getting 150rms. The sub woofer had a fairly good sized magnet considering its only a P1. However it is time to upgrade so i just ordered a Rockford Fosgate T0 2 Ohm 12" sub for Christmas. This product is recommended for beginner system.

I owned 2 of these awhile back and man did these things surprise me! Wayyy better than the old punch line. And its a great price to! Great entry level sub.
