    PDX V9 sub output

    Due to space limitation I have to resort to a compact 5 channel amp, I have looked at both the alpine pdx v9 and the JL HD 900/5. Now the Jl is really out of my budget but if I had the money I would have consider the Zed leviathan 111 over the Jl.

    My question is for anyone who have experience with the pdx v9, does the sub output section do rated power? I want to run a 10w6 v2 600w rms @ 2 ohms and an active 2 way front stage.

    Any help is appreciated.

    yes, I actually put one of these in not to long ago, small good clean solid amp, bunch of neat features like power reduction so it can cool, etc....i wouldn't hesitate.

    I have one and will introduce it to a bottle of tannerite if it does not sell on DIYMA.

    1. It has the infamous HISSSS
    2. It has both a turn on and turn off pop

    Aside from that, it does rated, comes with a birth sheet, and sounds like an amplifier from the 80s...



    I used to swear by old school car audio gear, now I swear at it!

    I have read mixed reviews, some say no hiss no pop some say it does have them, now I am wondering if it has to do with the install or possibly the vehicles.

    Might be installation variables.. might be internal issues. If you're seeing quite a few reviews stating it exists.. then it sounds like a design flaw.

    Well, replacing it with a known working amplifier solved both the hiss and pop with no additional changes, so you decide whether it was my vehicle or install...

    Prior to changing out the amplifier, I changed amplifier ground points 3 times, exposing shiny metal each and every time. I changed HU grounds 5 times, ultimately grounding at the same point as the amplifier. Still had noise. Grounded the shields on the RCAs thinking it was a Pioneer pico fuse issue, still had noise. I swapped HUs to a Clarion DXZ785USB, bypassed all previously run wires by wiring directly to the amplifier (power/ground/remote + different RCAs), yep still have hiss and pop. Pulled the RCAs, put a switch between the +12v and remote turn on lead, flip the switch on, pop, flip the switch off, pop. I plugged an iPod directly into the V9, as soon as I applied the slightest of volume, HISSSSSSS. Flip the switch, pop.

    I should have just gone with another JL Audio HD900/5 because my last one didn't have problems and I have better faith in JL Audio's customer service department. I never needed it, but it beats the heck out of sending an amp in with noise issues then having it sent back saying that it operates within spec (*cough*, *choke*, PDX-5)...

    ETA: Oh well, I just ended up using two spare Lunar Amplifiers that I was thinking about selling. A L450 for the mid and tweet along with a L100x2 bridged to the sub. Sure, they are inefficient class ab amplifiers, but they have no associated noise issues. I feel sorry for my buddy who was going to buy them from me though, lol.

    As did I. The local Alpine rep better hope I don't run into him until I cool down because I want to string him up by his nads right now! He assured me that the noise issues were a thing of the past. Lying sack of ish...

    Re: PDX V9 sub output

    Well the PDX V9 is out, I would going with the JL HD 900/5 over the Zed, because the Zed when bridged can only be used with a minimum 4 ohm load and my sub would be either 2 or 8 ohm, hence the JL amp would fit the slot nicely, more money but am sure it's well worth it.

    Thanks to all who have contributed.
