Noticed that my dealership connected my wetsounds double-up system to only two channels of my Alpine PDX-4.150. I bought the amp specifically to have 4 channels for the 4 tower speakers. I have some distortion at higher volume and wonder if it is due to the poor quality speaker wire and they way the system is wired. Is it worth re-wiring so that each speaker has its own channel? will allow me to adjust the frequency to the specific speaker as well.

Oh god yes, please rewire.
Now, there are two ways you can do this: (a) each speaker on its own chnl with each speaker having its own speaker wire pair running from the amp to the speaker. (b) you can wire each pair (Pro60's and MB8's) in series and the bridge each pair on half the amp. This is an 8 ohm load bridged and = the same 4 ohm p/chnl output as if you wired per (a). If you only have 2 speaker wire pairs running up the tower now, and they are 12ga, I would probably go with (b).Mikes Liquid Audio: Knowledge Experience Customer Service you can trust-KICKER WetSounds ACME props FlyHigh Custom Ballast Clarion LiquidLumens LEDs Roswell Wave Deflector And More -
For this set up you really need to have a tower harness of 8-conductors of no less than 14-gauge. With the dissimilar size of speakers you really want the ability to set the highpass crossovers and gains independently for the 60s and 8s. And, that requires that you operate in the 4-channel stereo mode. This will ensure you can tune the tower system for the optimum performance and take full advantage of the amplifier capabilities.

great. thank you!Comment

Do you guys have a ballpark recommendation on setting for AMP with these speakers? Crossover point? any HP, LP filters?
Thank you in advance for your helpComment

Both need to be on hi-pass. Set the 60's around 120Hz and the MB8's at 80HzMikes Liquid Audio: Knowledge Experience Customer Service you can trust-KICKER WetSounds ACME props FlyHigh Custom Ballast Clarion LiquidLumens LEDs Roswell Wave Deflector And MoreComment

Please help me understand I wants to be smart wit da steros too!LOL Just kidding!
Seriously help me understand how they had it..when I read the orignal post I thought he had like CHP suggested example B.. Wich is the way i would do it. But how did they have it? Thanx again.Last edited by kko; 06-11-2011, 03:04 PM.Comment

if i understood the OP's original post, they wired all 4 speakers to only half the amp.....basically only using 2 chnls of a 4 chnl amp. Normally, this is not really a bad thing, but with the above setup, it is on two fronts. One, you got two different speaker types being crossed over at the same point. This leaves one type compromised in some way. Next, I think the PDX has the same output at 4 ohm as it does at 2 ohm. So, two speaker on one chnl = the same watts as a single speaker. In the above set, this leaves the two under powered.Originally posted by kko View PostComment

Ok Ididnt read it like that but...why would they do that. Unless he told them he wanted room for expansion. When you run it like I want or CHP senerio B.. Your running the amp in 2 channel mode, Bridged-Half to the amp to the 60's and half to the 8's. right? Of course running like Dave suggested would be great but you would have to have alot more wire up there.I dont really know how they get that many speaker wires through the tower. Any tips on this you would care to share Dave? So I guess the big question is why in the world would they not use half the amp?Comment
