[QUOTE="blablablabla, post: 8115489, member: 655269"] Hello. First of all I'm new here... Second, sorry for my bad English, I'm not a native English speaker. I am very noob and don't have much knowledge on car audio systems so I need your help. I have the following speakers installation in my car: [LIST] [*]Front door speakers: Infinity Kappa 62.9i, 6.5" 2-Way, 2.0 ohms, 75 Watt RMS. [*]Rear Speaker: Infinity 9633i, 6"x9" 3-Way, 2.0 ohms, 100 Watt RMS. [*]Subwoofer: Sony Xplod XSGTX121LS, 12", 4.0 ohms, 300 Watt RMS. [/LIST] All this is powered through Premier PA854 4 Channels 3200 Max power Amplifier. (Very low quality amp...) Front & Rear speakers connected to channels 1&2 and the sub is bridged to channels 3&4. My problem is that the amp heats so much when listening to music loudly, that you can cook on it. So I decided to buy a new AMP and that where my questions begin: [LIST=1] [*]My speakers are 2ohm and the sub is 4ohm . Does it matter and what info should I look when buying an amp? For example there are 5 channel amps that say 4x80w+1x300w at 4ohm, or 4x160w+1x600w at 2ohm. But there aren't any combinations between 2ohms for speakers and 4ohms for the sub. How do I connect the sub at 4ohms and speakers at 2ohms ? [*]What amp is better? 5 channels or 6 channels ? The speakers are no problem - they are connected to 4 different channels. But the sub can be connected to 1 channel or 2 bridged together channels. What is better? [*]Please enlighten me if I forgot something important when choosing an amp. [/LIST] Oh, and my Head Unit that will operate all this is Pioneer AVH-X8500BT (has 3 Hi-volt RCA's). That's about it. P.S. Please advice me some choices where to start for good & not so expensive amps, what recommended manufacturers etc. Thanks in advance & have a good day.. Edited: Forgot to ask. Do I Need some power supply for this combination to work or 12v DC will be enough? [/QUOTE]
