moh.vze.com Posted May 2, 2012 Author Report Share Posted May 2, 2012 (edited) Here's an update: I just got my baffles today for the rear and I'm going to now install the rear speaker as well as swap my eD NiNe.2 for the PPI P900.4. It will be PPI P900.4 powering DLS MS6A (Rear) and HA Unity (Front Doors). Stay tuned for more pictures! I have a question for you all. I'm thinking about not screwing down the baffle to the rear but instead, I'm going to use my leftover Second Skin Audio Damplifier Pro to tape it down. I mean, the Damp Pro is pretty strong stuff, would I get away with this?

moh.vze.com Posted May 3, 2012 Author Report Share Posted May 3, 2012 Finally got my new Knu RCA runs and speaker wire runs back to the trunk for the 4 channel amp. I've never used a 4 channel amp before... I think I'm tuning it wrong because it's not as loud as my eD NiNe.2. What should my voltage reading be if I want 2x100W for the rear speakers? (20V*20V)/4Ohm = 100W? It doesn't seem right because my oscope doesn't show clipping even if I turn it over 40V.

Skullz Posted May 3, 2012 Report Share Posted May 3, 2012 I'm sure those speakers are quite capable of taking every bit of power from that amp and as long as your clip free you should be fine.

profundus-sanus Posted May 3, 2012 Report Share Posted May 3, 2012 100w @ 4 ohm = 20v what db test tone are you using? i really like that amp! 1/0 reducers and crossover section especially. Quote Link to comment Share on other sites More sharing options...
corey0928 Posted May 3, 2012 Report Share Posted May 3, 2012 I'm so mad i saw this amp right after i bought my 4channel. Keep the pics rolling through Quote Link to comment Share on other sites More sharing options...
moh.vze.com Posted May 3, 2012 Author Report Share Posted May 3, 2012 I used a 1k hz @ 0db tone. I will retune it again tonight to give my unity's 145w. I'm kinda liking having rear speakers in the back Quote DC Audio - Singer Alternators - Knukonceptz - XS Power - Hybrid Audio - Rockford Fosgate - Second Skin Audio - SMD - Sundown Audio - Elemental Designs Link to comment Share on other sites More sharing options...
profundus-sanus Posted May 4, 2012 Report Share Posted May 4, 2012 0db tone is a TON of headroom. on audacity i've never seen anything above 70hz be above -5db i've yet to venture into dubstep however... so who knows with that stuff.

moh.vze.com Posted May 4, 2012 Author Report Share Posted May 4, 2012 I found out why my speakers didn't sound as good off the PPI P900.4. I had my HPF turned the wrong direction on the amp. I use my headunit to tune everything (125hz HPF), but on the amp it was turned the other direction so everything was filtered out lol! Anyhow, I've retuned the front and rear speakers to all get ~150W and everything sounds a lot better and louder now. I still have to get more listening time before I decide on if the SQ of the PPI P900.4 is better than my eD NiNe.2. As of now, I think I'm getting a tiny noise, but I don't think that makes sense because I've upgraded new Knu RCA cables (more expensive ones) and only added 2 more runs of speaker wires for the rear. Here are the pictures! I know the wiring is a mess o_0.

moh.vze.com Posted May 4, 2012 Author Report Share Posted May 4, 2012 I haven't screw down those speakers yet or even applied any deadening. The rear speakers look clean because of the stock black cover thing haha.
