[QUOTE="gud, post: 8553947, member: 672522"] hey I'm fairly new to car audio. I understand the basics mostly but still need some help getting this all right. any help upgrading my current system would be awesome. I chose the parts before I knew anything and had a shop install it so I really don't have a whole lot of hands on experience, just from what I've read online. so this is my understanding of what's going on, but I may be wrong. please point out my flaws Current setup [LIST] [*]Right now I've got an amplifier that is rated at [I]1,200W RMS[/I] at [B]1-Ohm[/B]. That allows it to give out [I]800W RMS[/I] at [B]2-Ohm[/B], and [I]400W RMS[/I] at [B]4-Ohm[/B]. [*]I have a [B]Dual 4-Ohm[/B] 10 inch subwoofer that is rated at [I]275W RMS[/I]. Since my sub is a [B]Dual 4-Ohm[/B], when wired to the amp, the final impedance is [B]2-Ohm[/B]. (Info taken from [URL="https://www.sonicelectronix.com/product/img/subwoofer_wiring/1_sub_DVC_4_ohm_mono.jpg"]this photo[/URL]) [*]Since my amplifier is rated at [I]800W RMS[/I] at [B]2-Ohm[/B], and my [B]Dual 4-Ohm[/B] subwoofer is wired at [B]2-Ohm[/B] with [I]275W RMS[/I], I am overpowering the subwoofer by [I]525W RMS[/I]. [/LIST] My ideal choice is to upgrade my subwoofer, rather than my amp to save money. So here are my options. Option 1 [LIST] [*]Remove my current subwoofer and subwoofer enclosure, replace it with a dual subwoofer enclosure. [*]Purchase two [B]Dual 4-Ohm[/B] [I]200W RMS[/I] subwoofers. [*]When the two [B]Dual 4-Ohm[/B] [I]200W RMS[/I] subwoofers are wired to my amplifier, they will be wired at a [B]4-Ohm[/B] impedance with a combined total of [I]400W RMS[/I]. (Info from [URL="http://www.sonicelectronix.com/product/img/subwoofer_wiring/2_subs_DVC_4_ohm_mono_variation1.jpg"]this picture[/URL]) [*]Since my amplifier is rated at [I]400W RMS[/I] for [B]4-Ohm[/B], this is a perfect match and my subwoofers and amplifier will be at an equal RMS rating. (That's good, right?) [/LIST] Option 2 [LIST] [*]Remove my current subwoofer, purchase a [B]Dual 4-Ohm[/B] [I]750W RMS[/I] subwoofer and replace my current with that [*]Since the new subwoofer is a [B]Dual 4-Ohm[/B], when wired to the amp, it will give off [B]2-Ohm[/B] of impedance. [*]Since my amplifier is rated at [I]800W RMS[/I] for [B]2-Ohm[/B] setups, I would be overpowering my subwoofer by approximately [I]50W RMS[/I]. (This is much better than overpowering it as much as I currently am, correct?) [/LIST] Again I am a complete beginner when it comes to this stuff and am not sure if what I wrote is all correct. I would greatly appreciate any help fixing mistakes I made in my reasoning and help pick which the best option would be for an upgrade. Thanks guys [/QUOTE]
