Re: alpine 3523 no instructions or wiring

I know this is a little late but I have one and the hookup is very easy, On the right side of the amp there is a six pin plug. Above it it says BATT REMOTE GND. The two pins below BATT are the battery (V+). The pin below REMOTE is the (V+) switched turn on. The two pins below GND are the ground. The rest is simple. Two RCA inputs. The switch to select MONO(R), STEREO, or MONO(L) works as explained. If you want stereo, put the switch in the middle and supply two inputs and two speakers. The MONO(R) and MONO(L) are to select a single input that will supply a single (bridged) output. Connect two speakers and they will supply the same source or connect one speaker to the outer speaker terminals for higher power output. The variable or fixed switch just bypasses the GAIN CONTROL knobs(used for Alpine's 8 pin DIN plug on unit, for older EQ's and head units.

You definitely need a harness just to get the radio to play. Call alpine and see what kind of harness you need, then find one on ebay. You might be able to find a manual on their website in a PDF and download it.

Need help wiring two 10" alpine type E subs to a alpine 500 watt monoblock amp

Just connect both sets of wires from the subwoofers to the same speaker output terminals on the amplifier. Make sure you keep the positive and negative wires together. This is called parallel wiring. The Type E is a 4-ohm, single voice coil subwoofer, so wiring them like this will give the amplifier a 2-ohm load, and the power produced will be divided between the two subs.

Alpine pdx 1.000 keeps cutting out

You are going to want to make sure all your power wires and grounds are 4 gauge as well as the wire leads to and from the capacitor-4 gauge also. make sure you have a very good ground - the power wire from the battery should hit a distribution block-from the dist. block a 4 gauge should go to the capacitor another 4 gauge to the mono amp and another to the 4 channel amp -every component should have a good solid ground even if you have to bust out a grinder and a drill and some self tapping sheet metal screws and go nuts on it- see if that helps you

Power Protection Circuit (SORT) Engaged

Umm a ohm meter would help you here. Double check the wires from the sub to the amp...make sure its not shorting out. Try starting the amp without the wires on the terminals...if the protection shows up then there is a short inside the unit and it will need to be replaced/repaired.
