This might become a huge debate on the matter, but i'll try to keep it short and simple. Basically I'm trying to get the max power out of my setup and having a hard time deciding how to wire my subs up to either 2 ohm load or 4 ohm load. I wont list the brand of subs/amps im using because that...

So I looked at a forum about using a Line out converter to get RCA to the amp for subs. Everything went good and the subs in my trunk sound okay but the underseat subwoofers don't work anymore on either side. What could have gone wrong? I didn't slice the wires I took off the insulation to...

Hey so I just got this 95' E38, the rear deck speakers sound horrible. My car came with the factory DPS and I've researched that the 4 rear deck speakers are subs or woofers when the DSP comes with the car ? I was on Crutch Field .com asking for help on the live chat there and they said they...

Yes I have searched, but I can't find any complete answers. So far, I haven't been able to find any working setup with all 8 channels still working with an aftermarket headunit. Also to add upon that, I want this to be powered by an amp(s) and have found subs the size of the rear deck speakers...

Can someone please tell me how to unplug just the drivers side sub under the seat? There are many wires under there... I've tried researching but can't get a definite answer. Thinking about going with the Earthquake's everyone is talking about.

How should I go about doing this. I have the stock system. My car came with a year of Sirius radio, so I might have premium sound. Can I just connect subs to the stock amplifier? What size and how many subs should I do. Two 12" subs would be good, but I'm thinking two 10" would be a safer bet...
