Conclusion: Outstanding sound and power! I love this amp. Best one I've ever owned. It was so easy to install. When I'm out on the boat I always get comments that it sounds great. I run 6 X 9 coax JBL's , 100 w rms and this amp is all they can handle. So happy.
Conclusion: I had one of these 5 channels in a Saturn Aura. It only took up a very small space in the trunk. It is super handy that all the wire connections are on the same side of the amplifier. It keeps the install cleaner.
Summary: The top of the line. 4-channel + Mono = 5-channel. It's a 5-channel amp that has plenty of power for whatever system you're trying to run and it's small enough to mount to the back of a single sub box or under your seat like I did.
Summary: Plenty of power in a small package. Supplies distortion free sound. I am running Infinity's 6.5, Polks 4.5 and a Polk 10 inch sub. The Polk sub seems to have taken more power from the amp then a previous MTX sub, but still sounds great.
Summary: I bought the Alpine PDX-5 to power Alpine Type R componets in all 4 doors and a subwoofer in my Ford Explorer. This amp is exactly what I was hoping it would be. Small and lite so it was easy to conceal under a seat in the second row. I've had it a few months now and it's been completely reliable.
Summary: I am using this AMP to run my entire system. This amp works great. It is compact but powerful. I was running a Fosgate amp before and I have to say the sound quality completely changed for the better when I went with this Alpine amp.
