so it powers off? did you check the wiring?

 

Yeah, I checked the wireing and fuses. It's really strange that it powers off for about a second and then powers back up.

 

check the wiring. you could have crossed wires or something

 

When I was a 15, I put two 12's and a 800 watt amp in her ford focus, you know, cause I'd be driving soon. When I got my own car and pulled the subs and amps, she started bugging me about it sounding too hi pitched like she was listening to headphones . But she listens to a lil bit of everything from rap to rock to contemporary gospel. I tell ya, "no one" by Alicia Keys was the first song to knock my radar detector off the blazers windshield, lol.

Thogert, has it always done this or did it start out of no where? I know you have checked the wiring, do you have a voltage meter to see what power it's drawing? Is it grounded through the wiring harness? For some reason I've seen some units that wouldn't ground %100 through the harness.

My cousin had installed a old 1995 Pioneer cd player in the BMW I got off him and it would do that. Cleaned every connection, redid all the wiring connections in the dash, (he cut the factory harness out and hardwired everything, I F****** HATE THAT,) and I eventually grounded the headunit to the headunit itself and never had a problem agian. Just some things I've known to help problems like that. Shutting off for a split second sounds like a ground problem to me, or power supply problem, just my 2 cents though.

 

Im torn between 2 subs.

Alpine type R 15", or a Kicker solo baric L5 15".

Ive looked at the specs and they are the same im pretty sure. Are the square subs any better than the circles?

WHICH ONE SHOULD I GET?

 

squares are actually worse when it comes to recreating sound waves. i'd say go with the Rs but you're also going for 15s so you're not too worried about clean sound but rather loud i assume

 

Thanks guys I'll try rewireing it and see how it goes.

 

I am gonna guess you have your gains cranked up all the way on your amp(s) and when you turn up your head unit after your amps are running hot and drawing all the current possible and your deck powers off and on because it's not getting the required current. Your lights probably dim too, You would likely benefit by upgrading the big 3 wiring and setting your gains properly with an o-scope or the very least do some math and set your gains with a DMM.

 

No it turns out that the ground wire vibrated lose and was disconecting from the frame, I hadn't checked that. But thanks I appreciate the help.

 

Ok I just saw you had earlier said you checked the wiring so I didn't suggest checking the ground again as I figured that was checked.
