Hi all, I drive a '94 Mitsubishi 3000GT. The stock 21 year old stereo system scks hard and can't handle any bass, even at low volume. As a result I've been doing a ton of research into building a new audio system, and that brought me here. So far these are the parts I have picked out.
Amazon.com : Alpine SPR-60C 6.5" Car Audio Component System (Pair) : Component Vehicle Speaker Systems : Car Electronics
Alpine SPR-60C Component (Front- Tweeters will go in a spot on the dash)
Amazon.com : ALPINE SPR-69 6X9" 2-WAY COAXIAL SPEAKERS 300W PEAK / 100W RMS : Vehicle Speakers : Car Electronics
Alpine SPR-69 Coaxial (Rear)
Amazon.com : Alpine Swr-843d 8-Inch 1000 Watt Dual 4 Ohm Type R Subwoofer : Vehicle Subwoofers : Car Electronics
Alpine SWR-843D 8" (Sub- building a custom enclosure out of wood using manufacturer's recommended specs, plan to secure it using Velcro)
Here are the power ratings.
Front Components- 110RMS/330Peak per speaker, 4Ohm, 88dB
Rears- 100RMS/300Peak per speaker, 4Ohm, 90dB
Sub- 350RMS/900Peak 4+4Ohm, 83.5dB
So I have heard that for the best results I need an amp that will provide around 75% peak power to each channel. Obviously I will need an amp that is 4Ohms. This would mean that I would need an amp that gives around 225W per channel, but then what about the sub? Would I be better off getting a single powerful, 5 channel amp to power all of these speakers? Or should I get a weaker 4 channel amp for the speakers and a mono amp for the sub? I believe the sub has dual voice coils, so would I need a two channel amp for that or can I run it off a mono? Lastly, what gauge wire should I use? I have a good amount of room between my car's rear seats and trunk area (not enough for a sub), so I should be able to comfortably fit two amps if need be. I heave heard good things about Alpine, so I would prefer to stick with them but if there is something much better for less money I will consider it.
I have not done any research into head units yet, I don't need anything fancy like Bluetooth. All I need is an audio in port (3.5mm) so any recommendations would be great. If anyone sees a problem with the parts I have selected this far please let me know.
Thank you for any help.
Forgot to add my music preferences and budget. I listen to hip hop, rock, occasionally metal and reggae once in a blue moon. Never radio, always Spotify via my phone. I can spend as much money as I need to, but I would prefer to keep it under $750 or so excluding the HU. I don't need a crazy loud system because my car's cabin is pretty small, and I value sound quality over volume.
After a bit more research, if I don't end up getting the parts listed above, then I'm going to go with the following:
Infinity 6030cs 90RMS/270Peak 2Ohm Components
Infinity 9632cf 100RMS/300Peak 2Ohm Coaxial
Rockford Fosgate P3D210 10" Sub, 400RMS/800Peak 2Ohm
I'm kind of leaning toward this setup as it's a bit less money and I have heard several times that Infinity speakers are unrivaled in quality. Any amp recommendations for this setup would be appreciated, thanks again.
Okay I know this is turning into a wall of text, if you've made it this far thanks for your patience. After a bit more looking around, would a Pioneer GM-D8604 amp work with the listed Infinity speakers? It claims 150Wx4 when on 2Ohms. I would need a separate amp for the sub but I'm sure that won't be a problem. http://www.pioneerelectronics.com/PUSA/Car/Amplifiers/GM+Digital+Series/GM-D8604
