**** it if it works it works. Keep the amp and 8s, Add a mono amp and a 10-12 around 200rms and youll be happy. They have those truck boxes which are flat and are good for small areas.
I bought a speaker for 60 bucks with box not knowing if it worked, 3 years later my sub is still kicking by the way its was a rockford hx2. I like it so much I went looking for another untill I found it selling for $350 used.
That might be the best deal ever, I just wish I took his word and bought the bd amp to go with it. He wouldnt budge from $200, If I would have known I would have snatched it up. We all learn from are mistakes.
But anyways my first set up was that $60 sub, Alpine hu $60, 4 kenwoods 5 1/4 $45, And the bad ass pyramid amp $75...
You can see where I went wrong, I still have everything besides a pair of the kens I traded for a kicker 400. Kens and $50 for the kicker another sweet deal but it died a year later.
