Question about Alpine PDX-1.1000 1000W x 1 Car Amplifier Car Audio Amplifier
Posted by Anonymous on
using these subs will limit you to a 4 oh load to the amp witch will only let the amp produce half of it's power. the lowest ohm load that amp can handle is 2 ohm and the next lowest you can wire the subs is 1 ohm and that will over heat the amp and destroy it. so to answer your question first wire each sub like this diagram shows...
Wiring Option #1
then once both subs are wired this way you wire both positives from each sub to the positive side of the amps speakers terminals and wire each subs neg. to the amps neg speakers terminal. the wire is series parrelle and will present a 4 ohm load witch will be the safest to run with your amp.

SOURCE: I have the Alpine MRP-M1000
this amp is rated at 600w at 4 ohms and 1000w at 2 ohm so as long as you calculate your speakers to match the ohm specs of the amp you can hook up
parallel = pos to pos and neg to neg of the 2 speakres
2 - 8 ohm speakers in parallel = 4 omhs
2 - 4 ohm speakers in parallel = 2 ohms
series = pos to neg of the 2 speakers
2 - 1 ohm speakers in series = 2 ohms
2 - 2 ohm speakers in series = 4 ohms

Any time that there is a rattling sound from the subs, that indicates that they are probably blown. How were the subs tested ok? If the resistance of the subs is still close to OK, that is good, but it doesn't necessarily indicate that they are working properly.
Try using different subs at a lower volume, or turning down the gain slightly.

you can find your wiring diagram here
Select from the list shown which describes your amp and subs (ie 2 channel amp with 2 4ohm subs)
Hope this helps and please rate, thanks
