I will only use Alpine or Premier. Nothing else. But Alpine is the best option imo.

It's probably internally wired to make it look as if its a 2 channel amp. That just makes wiring subs easier. Does the amp have fuses? True mono block amps have no fuses.

I have an alpine CDA-9853. I'm not sure what would be the best way to set it up. The crossover has front/rear/sub, I'm not sure about the slope and what Hz to tune them to for best sound. I have the front / rear set to 100hz and the slope to 24. It goes flat/6/12/18/24. I would like some advice on how to tune these. The subwoofer setting is what I'm most concerned about. I have a FI BL 12 and blew it. Now in the process of re coning it =( I'm also not sure what to set my amps LPF to.... I was told 80hz but I want to be sure. Many people also mentioned bass boost being bad, is this true? And one more question, should I keep my subwoofer level on 0 at all times. Is it safe to set it around 8-12 before setting my gain? Clipping caused my sub to kick the bucket..... And I don't want that to happen again. Any advice would be greatly appreciated! I also need a skilled woodworker to create me a optimal box for this BL sub. =D

You interested in the amp for $110.00? It has low hours for it's age. And like i said it always pushed jl w3's (250 rms each) never abused with a higher powered subs. I dont need this thing let me know.

Oh yea, I almost forgot. I have a RF punch 500a2 old school amp I don't need. I was told these are pretty good amps. What would be a good price to ask for this amp? It is older but in great shape. And the original owner (my friend) used it for under a year on 2 jl w3 12's (oldest version) and then unhooked it. I need cash to recone my BL =(

One last question. You guys said 50 - 63 hz would be ok for my BL 12. Sould I set the LPF on the amp the the same as the Alpine deck frequency? Sorry I'm a noob when it comes to fine tuning everything. =D Just trying to get this set up the best I can.

Thanks for the info guys! Does anyone have suggestions on what to set the front / rear to for the highs. I'm just running the speakers off the deck for now, (low money) down the road I will get an amp for the highs.

If you want a decent amp for a great price check out Audiopipe. They are much better than Lanzar, Legacy, Pyramid, Boss, and all those insanely overrated amps. NEW!
