Interesting amp. I don't see any advantage over the 520.D with this amp with the exception that it's smaller. Same radio issues will exist and the 520.D has more power. That said it's a good amp for guys looking to save space and run 2 ohm speakers. Interesting because this amp cost more than the 520.D? Strange.

Yes Sir!!! It's a powerful little amp for what it cost. It's got the same internals as the sound stream 520.D but for what ever reason the dam thing puts out more power. My testing was strictly speaker to speaker. In other words using the titan II speaker as a reference I wired the soundstream to four speakers up front and it sounded pretty good. Switched out to the power acoustik and those speakers woke up big time!! and for the life of me I can't figure out why? My friend AAWAV has tested this thing on his scope and he can't find the difference either. But if you listen to the dam thing you can HEAR the difference. The PA brought the bass out of the Titan II's like I had never heard it before. So yes I'm still lovin' it. But anyone who follows this forum knows I'll switch it out this winter to test other amps. I'm looking at testing 3 amps this winter. The 4180, the Rockford T400X4AD and the Cerwin Vega B2/B4. Then I'm going to send them to AAWAV and let him test for real world power. We will post the results on this forum when we get it done.

I read the thread. Very interesting. Got me contemplating getting that amp over buying two PBR300x2. The BT 7P1's are on there way along with the Kappa 62.11i. Any opinions on what would be best?

My reply as always is this: You buy the RZ4 for the advertised price of $110.00 install it and don't like it. I'll buy it back from you no questions asked. I have not been able to find an amp to beat the power and value of this thing and trust me I've been looking and testing. . . lol. I can sell the amp in a day here in my area. These guys love it. But on the other hand all they care about is their music. They could care less about FM around here. . . too many Bluetooth radio apps.
The two PBR's are going to be a little more labor intensive to install but if you are an FM guy go with the two PBR's. But if you want to hear the 7.1's like they should be heard go with the PA. My .02.

Well $109.95 the RZ4 will be here on the 8th. I have 2 pairs brand new MM651 and new PN4.520D still in the box heading back to Amazon in the morning. Waiting on the BT 7P1's and pair of the Kappa's 62.11i should be here by the 8th also.

Dam Poolboy . . . That's a nice little amp as well. I'll have to put that on my list! Where do you find these nice amps? I'm looking at amps everyday and I had not ran across this one!
