And you have to encompass the next portion into the plan as well:
Goals are a different story all together. They are limited by the budget (hard to win the world SPL championship on a 200 dollar budget.
One also has to be realistic about their goals.Yoiu can try to achieve anything but you have to be happy with what you have which was inherently limited by your budget and abilities.
You can do anything if you have the time and money to put into it.
Between TundrSQ and myself, we have outlined a reasonable cost effective plan using what you already have with upgrade potential.
Use current headunit's single set of RCA outputs with Y adapters to get the signal to the amp
Use current Rockford 4 channel amp to either power one or both sets of door and 6X9 speakers off the front channels. If you only power one set, then the second set is powered by the head unit
Use current Rockford 4 channel amp to power a subwoofer of bridged rear channels
Purchase sub and enclosure
Mono sub amp to free up rear channels of rockford amp to drive interior speakers
A better head unit
I think with your budget, you buy a decent subwoofer and stick it in the cheapest sealed box you can. Make sure the sub is either a single voice coil 4 ohm sub or a dual voice coil 2 ohm per coil sub.
This will let you get a second sub and more easily let you add in a mono sub amp that only has to drive a 2 ohm load. THEN you get a custom enclosure design.
Dealing with the 20-30 young guys that have all come through my garage (friends of my son and nephew), some have been wanting nothing but Bass, others were claiming to want sq with a little bass. All were wanting to do it on a highschoolers budget and were willing to skimp on the really important things. Like adequate wire, a plan, safety, subwoofers etc..
Thankfully you have a pretty good start.
