Sony Xplod 2-Channel 1000 Watt Amplifier trouble shooting
I have a sony Xplod amp and it doesn't seem to be working properly. The other sony speakers in the car seem to have more base than the ones running through the Xplod. I have checked the settings on my cd player and they are set to max for the Sub. Am I missing something?

You should definately bridge them. Firstly, lay the 2 speakers face down next to each other. Note the connections +- +-. The first + will go to the amplifier. The next terminal(-) will be connected to the next speaker(+). Take the last(-) and connect to amplifier. Please note that your amplifier has a bridge section which is normally the first + and the last- on the two channels. Connect your woofers on the bridge.
asuming the 8s are 4ohms each; wire two in series and that gives you 8ohms then two more in series then you put those together in parallel and it gives you a 4ohm load. repeat with other four for the other side. you should then be able to bridge the sub
series; posative of one speaker to negative of other speaker and that doubles your ohms
parallel; posative to posative negative to negative and that cuts the ohms in half
IF THE RMS IS 800 THEN THAT IS THE MINIMUM YOU SHOULD RUN TO THEM. IF THE MAX IS OVER 1000 WATT, YOU SHOULD BRIDGE ONE SPEAKER TO EACH CHANNEL. YOU WILL PUSH THE MOST POWER TO THEM THAT WAY. MORE POWER = MORE BASS
The head unit may be rated at 200 watts but it cannot produce more than ~20 watts of real power per channel. There's no way that it can drive the high end speakers to a level that will be needed to compete with the subs on a 1000 watt amplifier.
Almost all after market amps use 12v at very very low amperage to trigger the amp on. A temporary jumper from the battery plus terminal on the amp AFTER the battery and ground wires are attached should cause the amp to turn on. I would check to see if you have attached your speaker load correctly ESPECIALLY if you are bridging. Most of the blown amps that come into my shop are due to incorrect bridging loads from the speakers. Note that a 4ohm load bridged across both outputs of an amp will deliver a 2ohm load to each of the channels. When you parallel wire two 4ohm speakers together and then attached them to a bridged amp you will be putting a 1 (one) ohm load to each channel of the amp. Please don't make this mistake. It will fry your amp in about a month. Hope this helps. Good luck.
