Question about Lanzar Car Audio & Video
I have two subwoofers and on the amp for the speaker conection there is only one positive and one negetive. How do I hook up both of my subwoofers? Do I twist the two positive wires from both of the subs together and the same for the negetive?
Thanks Paul. I'm getting the speakers next week. the ones I had I sold because they where only 550 watss rms ( vibe cbr 12 ) I did'nt want to fry them. I'll find out the name of the speakers maybe tonight and write back. The place where i purchased the amp also have the speakers that where designed for that amp I ordered them and they will not be in till next week but I'll ring them back and get all the specs.

Firstly, sorry to to tell you, but their is no such thing as a 4000 watt car amp. Google Ohm's law and RMS .
Check the owners manual or website to find the amps minimum impedance. Usually 4 or 2 Ohms. Next,
check the woofers impedance , If unsure check with a Ohmmeter,
It's actually the resistance,but close enough.
If they are 8 Ohm and you twist those wires together (parallel circuit) your amp will see 4 Ohms.
If they are 4 Ohms (paralleled) your amp will see 2 Ohms.
Do not connect in a series circuit (+ amp terminal to a + speaker terminal and that speaker - terminal to the other speakers + terminal and that speakers - terminal to the - amp terminal) .
It creates phase problems, and sounds like ****.
Most mono amps are really internally bridged stereo amps ,it's cheaper that way, but it limits how low of a impedance they will handle. Read the specs. Use the correct size connectors, scrape off paint for a good ground connection.Use the right gauge wire and above all. Fuse that power lead at the Battery!!!!!!!!
ps . if you have dual voice coils thats another chapter.
Good luck, Sumthin
