Aftermarket Radio Opinions Wanted
@jbc426 can you recommend a DSP that works well? Preferably something that doesnt break the bank..haha
The old adage, "Speed cost money. How fast do you want to go?" applies here too. What is your budget? I can share which components I would use, given your budget if you like.
Take a look on Woofer's etc and Crutchfield's web-site, and then individually shop each item on the web for the best deal. It all depends on your budget, but remember you are eliminating the head-unit. I would then spend that saved money for that on better speakers and DSP.
A DSP with 6 channels can drive two small tweeters, a mid-base and a sub-woofer. The sub-woofer can use 2 of the channels in a "bridged" mode to essentially double the power to it. You can also run a nicer set of 2 channel 6x9's wired so you can adjust the tweeter and the main speaker. You don't have to buy speakers that use a passive crossover, which you would not need. Look at individual speakers i.e. tweeter's, mid-base's and sub-woofers.
You can always add a trunk mounted sub later as budget and needs allow. The 4 channel DSP's are is nice too, because you can can pass through the signal to a self-powered sub-woofer later.
A DSP allows you to electronically cross-over each speaker to it's optimum frequency response, adjust the listening position using the time-delay function (able to virtually positioning each speaker electronically) and have an equalizer to tailor the sound to you taste.
